Overview

The Thermo Scientific Heraguard ECO 1.8 creates a clean work environment by supplying HEPA-filtered air horizontally across the work surface. This unidirectional airflow helps continually sweep airborne particles away from samples and materials, reducing the potential for particulate contamination during sensitive laboratory and manufacturing procedures.

The ECO 1.8 is the 6-foot configuration in Thermo Scientific's Heraguard ECO family. Its interior work area measures approximately 71.6 inches wide by 23 inches deep by 25.4 inches high, providing ample space for multiple samples, instruments, trays, components, and other materials that need to remain within the clean zone.

A notable feature of the Heraguard ECO design is its use of energy-efficient DC motor technology. In addition to reducing energy consumption compared with traditional AC motor designs, lower motor energy use can reduce the amount of heat released into the laboratory. This can be especially beneficial in facilities operating multiple airflow devices continuously.

The Heraguard ECO also operates at less than 55 dBA, helping reduce background noise in laboratories where clean benches may operate for extended periods.

Common Applications

The Thermo Heraguard ECO 1.8 is designed for nonhazardous applications in which protecting samples or products from airborne particulate contamination is the primary objective. Typical applications include sterile media preparation, plant tissue culture, nonhazardous sample preparation, appropriate pharmaceutical preparation procedures, medical device assembly, electronics assembly and inspection, optical component handling, and other contamination-sensitive procedures.

Its six-foot workspace provides additional room for applications involving multiple containers or pieces of equipment and for workflows that require a larger clean work zone than a conventional 3-foot or 4-foot clean bench can provide.

Because horizontal airflow ultimately travels toward the operator, the Heraguard ECO 1.8 should only be used with materials that do not require personnel or environmental containment.

Ideal Laboratory Environments

The Thermo Scientific Heraguard ECO 1.8 is well suited for biotechnology laboratories, pharmaceutical facilities, medical device manufacturers, electronics facilities, cleanroom environments, university research laboratories, hospital laboratories, quality-control departments, and industrial production environments.

The combination of a six-foot work area, quiet operation, and energy-efficient DC motor technology can be particularly advantageous in laboratories that operate clean benches for long periods or maintain several airflow devices within the same room.

Refurbishment & Testing

Used laminar flow clean benches should be thoroughly evaluated before being returned to laboratory service. American Instrument Exchange inspects and tests refurbished Thermo Scientific clean benches before shipment, including evaluation of blower operation, controls, lighting, work area condition, and overall cabinet functionality.

HEPA filter condition is also an important consideration when purchasing a used clean bench. Filter condition and the specific configuration of individual units can vary, so customers should contact AIE regarding the filter status, work surface, accessories, and other equipment included with the particular Heraguard ECO 1.8 being offered.

Each refurbished Thermo Scientific Heraguard ECO 1.8 from American Instrument Exchange includes a 90-day warranty.

Certification Readiness & Service

Proper airflow velocity and HEPA filter integrity are essential to maintaining the controlled environment expected from a laminar flow clean bench. Following transportation and installation, clean benches should be evaluated according to applicable laboratory procedures before being placed into critical service.

American Instrument Exchange works with AIE Laboratory Services to provide field support for laboratory airflow equipment throughout Greater Boston and New England. Services can include airflow testing, HEPA filter evaluation and replacement, troubleshooting, preventative maintenance, and related laboratory equipment service.

Final testing after relocation is especially valuable because transportation, installation conditions, room airflow, and filter condition can influence clean bench performance.

Shipping & Installation

The Thermo Scientific Heraguard ECO 1.8 measures approximately 74.8 inches wide by 31.9 inches deep by 46.1 inches high and weighs approximately 355 pounds.

A supporting stand is not included with this particular unit. Customers should therefore plan for an appropriate laboratory bench, work surface, or compatible supporting stand capable of safely supporting the clean bench and positioning the work surface at a suitable operating height.

Laboratories should also confirm doorway dimensions, corridors, elevators, loading areas, and the final installation location before delivery. Adequate clearance around the clean bench should be maintained according to manufacturer installation requirements to avoid interfering with airflow or equipment operation.

American Instrument Exchange can assist customers with freight coordination and provide additional dimensional or configuration information for planning delivery and installation.

Related Equipment

Laboratories considering the Thermo Scientific Heraguard ECO 1.8 can explore additional clean benches and laminar flow hoods available from American Instrument Exchange, including different widths and configurations as well as units supplied with supporting stands.

For applications involving biological hazards or other materials requiring personnel and environmental containment, AIE also carries refurbished biosafety cabinets from Thermo Scientific, Baker, Labconco, Nuaire, and other major manufacturers.

American Instrument Exchange also stocks complementary laboratory equipment including CO2 incubators, laboratory refrigerators, laboratory freezers, and centrifuges.

Clean Bench vs. Biosafety Cabinet

The Thermo Scientific Heraguard ECO 1.8 is a horizontal laminar flow clean bench, not a biosafety cabinet. Its primary purpose is product protection. HEPA-filtered air flows horizontally through the clean work area and ultimately toward the operator.

A Class II biosafety cabinet uses a different airflow design to help protect personnel, products, and the surrounding environment when appropriate biological materials are handled.

For this reason, the Heraguard ECO 1.8 should not be used for infectious agents, biohazardous samples, toxins, radionuclides, hazardous chemicals, or other materials requiring personnel or environmental containment.

Laboratories working with biological hazards should instead consider an appropriate Class II biosafety cabinet. For nonhazardous procedures where sample cleanliness and particulate control are the primary objectives, a clean bench or laminar flow hood may be the appropriate choice.

Testing Procedures for Used and Refurbished Biosafety Cabinets

Ensure Containment, Airflow Integrity, and Operator Safety

Used and refurbished biosafety cabinets (BSCs) from American Instrument Exchange are thoroughly tested to ensure they meet NSF/ANSI 49 performance standards for containment, airflow uniformity, and HEPA filtration. Each Class I, II, or III unit is evaluated through a series of specialized inspections and certifications, ensuring the cabinet performs reliably in research, clinical, and pharmaceutical lab environments.

Why Testing Used Biosafety Cabinets Is Essential

Before any biosafety cabinet is deployed in a working lab, it must be tested for:

• HEPA filter integrity and leak-free performance
• Inflow and downflow air velocity balance
• Containment efficiency and personnel protection
• Electrical system function and safety compliance
• Cleanliness and readiness for sterile applications

Proper testing of refurbished biosafety cabinets helps prevent cross-contamination, exposure to hazardous materials, and airflow disruption—critical for maintaining laboratory protocols. Our structured multi-point BSC testing protocol ensures dependable protection for operators, products, and the lab environment.

Key Testing Procedures for Refurbished and Used Biosafety Cabinets
