Refurbished Thermo Scientific 1345 Biosafety Cabinet for Sale

The Thermo Scientific 1345 is a 4-foot Class II Type A2 biosafety cabinet designed to provide personnel, product, and environmental protection for cell culture, microbiology, pharmaceutical research, biotechnology, clinical research, and other contamination-sensitive biological applications. Part of Thermo Scientific's proven 1300 Series A2 platform, the 1345 combines a space-efficient 4-foot footprint with a one-piece 304 stainless steel interior, 10-inch working sash opening, intelligent airflow management, and energy-efficient brushless DC motor technology.

With approximately 47.2 inches of interior width, the Thermo 1345 provides substantial working space while requiring considerably less laboratory floor space than a 6-foot biosafety cabinet. This balance makes the 1345 particularly well suited for laboratories where available space is limited but researchers still need enough room for culture vessels, pipettes, media bottles, sample racks, and other materials used during routine biological procedures.

The 10-inch work aperture provides generous access to the interior chamber and distinguishes the 1345 from Thermo 1300 Series configurations built around an 8-inch operating opening. For laboratories replacing an existing 10-inch-opening cabinet or researchers who prefer greater vertical access to the work area, the 1345 provides a particularly practical configuration.

The cabinet's one-piece 304 stainless steel interior is another important advantage. Stainless steel provides a smooth, durable surface well suited to frequent cleaning and disinfection, making the 1345 an attractive choice for cell culture laboratories and other environments where contamination control is a daily priority.

At American Instrument Exchange, every Thermo Scientific 1345 biosafety cabinet is inspected and tested by our technicians prior to shipment. Unless otherwise specified, new HEPA filters are installed at our facility before delivery. This unit includes a stand and a 90-day warranty from American Instrument Exchange.

Overview

The Thermo Scientific 1345 combines the proven biological containment technology of the 1300 Series A2 platform with a compact 4-foot footprint, stainless steel chamber, and comfortable 10-inch operating opening. This combination makes it particularly useful for laboratories that need a full-featured Class II Type A2 cabinet but cannot dedicate the additional floor space required by a 6-foot model.

As a Class II Type A2 biosafety cabinet, the 1345 is designed to provide personnel, product, and environmental protection. Inward airflow through the front opening helps protect the operator from aerosols generated within the cabinet. HEPA-filtered vertical downflow helps protect samples and materials from airborne contamination, while exhaust air passes through HEPA filtration before leaving the cabinet.

Thermo's 1300 Series airflow system uses independent supply and exhaust blowers to help maintain the appropriate relationship between downflow and inflow/exhaust velocities. Electronic airflow monitoring provides users with operating information and alerts them when conditions move outside acceptable parameters.

The 1345's one-piece stainless steel interior provides a durable environment for everyday biological research. The smooth chamber surfaces and removable stainless steel work tray facilitate routine cleaning and disinfection, an important consideration in cell culture, microbiology, pharmaceutical, and biotechnology laboratories.

Unlike larger 6-foot models, the 1345 provides these capabilities in a cabinet measuring approximately 51.2 inches wide externally. This makes it easier to incorporate into smaller laboratories, individual cell culture rooms, equipment-dense research facilities, and laboratory expansions where available floor space is at a premium.

Why Choose the Thermo Scientific 1345?

The Thermo Scientific 1345 is particularly well suited for laboratories prioritizing efficient use of space, stainless steel construction, operator access, and energy-efficient operation.

Its 4-foot format provides enough room for most routine cell culture and biological research procedures without consuming the floor space required by a larger cabinet. For laboratories where a single researcher typically works at the cabinet, the 1345 can provide an excellent balance between usable workspace and overall footprint.

The 10-inch sash opening is another important consideration. Compared with an 8-inch-opening configuration, the 1345 provides additional vertical access to the chamber. This can make it easier to introduce culture vessels, equipment, and other materials into the cabinet while maintaining the operating aperture specified for the unit.

The stainless steel interior adds long-term durability and simplifies routine cleaning. For laboratories that disinfect their BSC frequently or simply prefer stainless steel chamber construction, the 1345 provides this feature without requiring a larger cabinet.

Energy efficiency also distinguishes the 1300 Series from many earlier biosafety cabinet designs. Thermo specifies approximately 200 watts during normal operation and 70 watts during reduced-flow operation for the 4-foot, 10-inch configuration. Reduced energy use can lower both direct electrical consumption and the amount of heat released into the laboratory.

For biotechnology companies, pharmaceutical laboratories, universities, hospitals, startups, and other life-science organizations, a professionally refurbished Thermo 1345 provides an attractive combination of containment performance, manageable footprint, durable construction, and acquisition value.

A Space-Efficient BSC for Cell Culture Laboratories

Not every laboratory benefits from installing the largest biosafety cabinet that will physically fit in the room. In many cell culture facilities, the ability to place multiple workstations, incubators, centrifuges, refrigerators, and other equipment efficiently can be more valuable than maximizing the width of a single BSC.

The Thermo 1345's 4-foot format makes it particularly useful for these environments. Its approximately 47.2-inch-wide interior provides enough room for common cell culture procedures while the 51.2-inch exterior width helps conserve valuable laboratory floor and wall space.

For startup laboratories and expanding biotechnology companies, this can also make it practical to install multiple 4-foot cabinets rather than relying on a smaller number of larger shared workstations. Dedicated cabinets can help laboratories organize separate research groups, cell lines, or workflows according to their own contamination-control procedures.

The 10-inch operating opening further improves access to the work chamber, while the stainless steel interior provides the durability required for routine cleaning and repeated daily use.

Thermo Scientific 1345 vs. Thermo Scientific 1305

The Thermo Scientific 1345 and 1305 are both 4-foot, 120V Class II Type A2 biosafety cabinets from the 1300 Series, making them natural alternatives for laboratories comparing refurbished Thermo BSCs.

The most important difference is the operating sash height. The Thermo 1345 uses a 10-inch working opening, while the Thermo 1305 uses an 8-inch working opening.

Laboratories that prefer greater vertical access to the work chamber may therefore favor the 1345. An existing facility replacing a 1305 or standardizing multiple cabinets around an 8-inch operating aperture may prefer that configuration instead.

Both provide the space efficiency associated with a 4-foot BSC, so the choice between them can often come down to sash-height preference, chamber configuration, available inventory, and the requirements of the laboratory's existing workflow.

Compatible Laboratory Equipment

The Thermo Scientific 1345 fits naturally into cell culture, biotechnology, pharmaceutical, microbiology, and clinical research workflows where samples routinely move between several pieces of laboratory equipment.

For cell culture applications, the 1345 is frequently paired with CO₂ incubators for maintaining cultures, refrigerated centrifuges for harvesting and processing samples, laboratory refrigerators for storing media and reagents, and ultra-low temperature freezers for long-term preservation of biological materials.

Inverted microscopes, laboratory autoclaves, water baths, cryogenic storage systems, and additional biosafety cabinets can further support complete biological research workflows.

American Instrument Exchange maintains a broad inventory of professionally refurbished laboratory equipment, allowing laboratories to source multiple compatible instruments from a single supplier while simplifying procurement and reducing equipment lead times.

The Thermo 1345 is a 4-foot biosafety cabinet. The cabinet itself measures approximately 51.2 inches wide externally and provides approximately 47.2 inches of interior working width.

This distinction is important when planning laboratory layouts or replacing an existing cabinet. American Instrument Exchange recommends checking both the cabinet dimensions and the complete delivery route before ordering.

Does the Thermo 1345 have a stainless steel interior?

Yes. The Thermo Scientific 1345 features a one-piece 304 stainless steel interior and stainless steel work surface. This distinguishes it from certain other Thermo 1300 Series configurations that use a SmartCoat interior.

Stainless steel provides a durable, smooth chamber well suited to frequent cleaning and disinfection, making the 1345 particularly attractive for cell culture and other contamination-sensitive laboratory applications.

Why would I choose the Thermo 1345 instead of the Thermo 1305?

Both models are 4-foot Class II Type A2 cabinets with stainless steel interiors. The major difference is the operating aperture.

The Thermo 1345 has a 10-inch working opening, while the Thermo 1305 has an 8-inch working opening. Laboratories that prefer additional vertical access to the work chamber may favor the 1345, while facilities replacing an existing 1305 or standardizing around an 8-inch opening may prefer that configuration.

Should I choose a 4-foot or 6-foot biosafety cabinet?

A 4-foot cabinet such as the Thermo 1345 is an excellent choice for many routine cell culture, microbiology, pharmaceutical, and biotechnology procedures. It provides substantial workspace while conserving laboratory floor space.

A 6-foot cabinet may be preferable when procedures require larger instruments, unusually high sample volumes, numerous culture vessels, or multiple pieces of equipment inside the work area.

For laboratories outfitting multiple workstations, several 4-foot cabinets may sometimes provide greater workflow flexibility than a smaller number of 6-foot units. American Instrument Exchange can help customers compare available configurations when planning a laboratory expansion.

Is the 10-inch sash opening useful when working with equipment inside the cabinet?

The 10-inch operating aperture provides additional vertical access compared with an 8-inch-opening cabinet. This can make it easier to introduce culture vessels, racks, containers, and appropriately sized equipment into the work area.

Equipment placement must still be planned carefully. Objects should not obstruct the front or rear airflow grilles, and equipment used inside the cabinet should be appropriate for the available workspace and the laboratory's containment procedures.

What do SmartFlow and Digital Airflow Verification do on the Thermo 1345?

Thermo Scientific's SmartFlow system helps compensate for changes in airflow resistance as the HEPA filters load over time. Digital Airflow Verification monitors cabinet operating conditions, while the SmartFlow indicator provides a visual indication of the system's remaining airflow compensation capability.

These systems provide useful monitoring between certification visits, but they do not replace routine field certification of the biosafety cabinet.

What does a CAL message or airflow alarm on a Thermo 1345 mean?

A CAL message or persistent airflow alarm indicates that the cabinet's airflow or monitoring system requires attention. Potential causes can include calibration status, HEPA filter loading, blower performance, sash position, or another condition affecting airflow.

A cabinet displaying a persistent airflow warning should be evaluated rather than assumed to be operating correctly.

For customers throughout New England, AIE Laboratory Services can troubleshoot Thermo 1300 Series biosafety cabinets, evaluate airflow performance, perform necessary repairs, replace filters when required, and recertify the cabinet following service.

Are new HEPA filters installed in this refurbished Thermo 1345?

Unless otherwise specified, American Instrument Exchange installs new HEPA filters prior to shipment. The cabinet is inspected, cleaned, tested, and prepared for field certification following installation at the customer's laboratory.

Installing new filters during refurbishment provides customers with a known starting point for one of the most important consumable components in the cabinet.

Yes. American Instrument Exchange sells individual refurbished laboratory instruments, and customers can contact us with questions about the condition, configuration, included accessories, or other details of the specific unit being offered.

Additional photographs or information about the actual cabinet may be available upon request. This can be particularly useful when laboratories need to verify cosmetic condition, stand configuration, utility fixtures, or other details before purchasing refurbished equipment.

Can American Instrument Exchange arrange inside or white-glove delivery for the Thermo 1345?

Depending on the destination and project requirements, American Instrument Exchange can assist with freight, inside delivery, and equipment-placement planning.

A 4-foot cabinet such as the 1345 is generally easier to maneuver than a 6-foot BSC, but it remains a large precision laboratory instrument. Customers requiring liftgate service, inside delivery, placement, or other special handling should discuss these requirements with American Instrument Exchange when requesting a quote.

Does the Thermo Scientific 1345 need to be certified after delivery?

Yes. The cabinet should be field certified after installation and before being placed into biological service. Certification confirms airflow performance, HEPA filter integrity, and other containment parameters in the actual laboratory environment.

Regular recertification should also be incorporated into the laboratory's biosafety cabinet maintenance program, particularly after relocation, HEPA filter replacement, or service that could affect containment performance.

Do you sell replacement parts or HEPA filters for the Thermo 1345?

American Instrument Exchange generally retains available used components to support the refurbishment and repair of additional Thermo 1300 Series cabinets rather than routinely selling used parts individually. Depending on the component and current availability, however, we may be able to help customers identify or source an appropriate replacement.

Replacement HEPA filters can be sourced through manufacturers and qualified filter suppliers. Because HEPA filter replacement can involve exposure to the contaminated side of the filtration system, appropriate biosafety procedures must be followed.

For customers in New England, AIE Laboratory Services can provide cabinet decontamination, HEPA filter replacement, testing, and subsequent certification.

I purchased my Thermo 1345 somewhere else. Can AIE Laboratory Services still service it?

Yes. The cabinet does not need to have been purchased from American Instrument Exchange for AIE Laboratory Services to certify, maintain, troubleshoot, or repair it.

Customers who cancel orders after refurbishing has begun will be subject to a cancellation and restocking fee of between 20% and 40%.

Are discounts available for educational or non-profit institutions, or for bulk purchases?

Yes – call or email us today with a list of equipment you're looking for and we can potentially put together a quote that includes a discount.

How does your price matching policy work?

We strive to keep our pricing competitive and reasonable. If you find comparable items for sale at a lower price from other vendors please send us a link and or quote for the item and we'll do our best to match or beat the price.

Can I see the equipment in person before committing to a purchase?

Customers are welcome to make an appointment to view equipment in our warehouse. Given our workload we may not be able to test or clean the equipment prior to your arrival if you have not committed to an order.

1023 Western Avenue is a working warehouse, not a showroom, and customers should dress appropriately and wear closed toe shoes.

Can I ship products that I purchased elsewhere to American Instrument for repair?

Yes – please see our repair services page for more information.
