Overview

The VWR GTVWG30CPGA provides laboratories with a combination of substantial refrigerated storage capacity and convenient visual access to stored materials. Unlike household or commercial refrigerators, laboratory refrigerators are designed around the requirements of scientific environments, where temperature monitoring, organized storage, and reliable operation are important considerations.

The unit's glass door allows researchers to locate materials before opening the refrigerator. This can be particularly valuable in shared laboratories, where frequent access by multiple users can otherwise result in extended door openings while samples or reagents are located.

Adjustable shelving provides flexibility for storing bottles, reagent containers, media, sample racks, boxes, and other laboratory materials of different sizes. The upright configuration also makes efficient use of laboratory floor space while providing substantially greater storage capacity than undercounter refrigerators.

For laboratories replacing an aging refrigerator or expanding available cold-storage capacity, a refurbished VWR GTVWG30CPGA can provide a cost-effective alternative to purchasing a comparable new laboratory refrigerator.

Common Applications

The VWR GTVWG30CPGA can be used for refrigerated storage of laboratory reagents, prepared media, buffers, biological samples, research materials, analytical standards, diagnostic materials, and other products requiring controlled refrigerated conditions.

Typical applications include molecular biology, biotechnology research, pharmaceutical development, biomedical research, microbiology, chemistry, clinical research, quality control, analytical testing, and general laboratory cold storage.

Because storage requirements vary considerably among laboratory materials, users should always verify that the refrigerator's operating conditions are appropriate for the specific samples, reagents, or products being stored.

Ideal Laboratory Types

The VWR GTVWG30CPGA is well suited for biotechnology companies, pharmaceutical laboratories, academic research institutions, universities, hospitals, biomedical research facilities, molecular biology laboratories, microbiology laboratories, analytical laboratories, clinical research facilities, and industrial quality-control laboratories.

Its glass-door design is especially useful in shared research environments and laboratories maintaining a large working inventory of frequently accessed reagents and supplies. Being able to visually locate materials before opening the refrigerator can improve workflow while helping reduce unnecessary temperature disturbances.

Temperature Recovery & Uniformity

Reliable temperature performance is an important consideration for any laboratory refrigerator. The VWR GTVWG30CPGA uses forced-air refrigeration to circulate cooled air through the chamber, helping maintain appropriate refrigerated conditions across the storage area.

Forced-air circulation is particularly useful in larger upright refrigerators because stored materials, shelves, and containers can influence airflow throughout the chamber. Maintaining appropriate spacing between stored items helps refrigerated air circulate effectively.

The glass door allows users to identify materials before opening the cabinet, potentially reducing door-open duration. Shorter door openings limit the amount of warmer laboratory air entering the chamber and can help the refrigerator return to its normal operating conditions more quickly following routine access.

Actual temperature performance and recovery will depend on ambient laboratory conditions, refrigerator loading, shelf arrangement, ventilation, door-opening frequency, and equipment condition.

Sample Storage Recommendations

Laboratories should organize the GTVWG30CPGA so refrigerated air can circulate around stored materials. Shelves should not be overloaded or arranged in a manner that substantially restricts airflow.

Frequently accessed reagents and samples can be positioned in easily visible and accessible locations. The glass door makes it possible to identify many stored materials before opening the cabinet, reducing the time required for retrieval.

Temperature-sensitive materials should not be placed directly against interior air outlets or other areas where local conditions may differ from the primary storage space. Laboratories maintaining high-value materials should also consider independent temperature monitoring and documented procedures for responding to temperature alarms, power failures, or refrigeration problems.

The GTVWG30CPGA should not be assumed to be suitable for flammable or volatile materials unless the individual unit is specifically labeled and rated for that purpose. Laboratories storing flammable materials should use equipment specifically designed for flammable-material storage.

Energy Efficiency & Operating Costs

Laboratory refrigerators typically operate 24 hours per day, making energy consumption and refrigeration efficiency important considerations over the life of the equipment.

Several factors affect actual energy consumption, including ambient laboratory temperature, refrigerator setpoint, frequency and duration of door openings, sample loading, ventilation, condenser condition, and refrigeration-system performance.

The glass-door configuration provides an operational advantage in frequently accessed laboratories because researchers can identify stored materials without opening the refrigerator. Reducing unnecessary door openings can decrease warm-air infiltration and reduce the amount of work required from the refrigeration system to restore chamber conditions.

Routine maintenance is also important. Keeping the condenser and ventilation areas clean and ensuring that door gaskets seal correctly can support efficient refrigeration performance and extend equipment life.

Refurbishment & Testing

This VWR GTVWG30CPGA glass-door laboratory refrigerator is supplied used and refurbished by American Instrument Exchange.

Before shipment, our technicians inspect, clean, and test the refrigerator to verify proper operation. Temperature-controlled laboratory equipment is tested using NIST-traceable temperature probes and data logging equipment as appropriate to confirm temperature performance.

The refrigerator is operated under refrigerated conditions to verify its ability to reach and maintain an appropriate laboratory refrigeration temperature. Temperature controls, displays, alarms, glass door, hinges, handles, door gasket, lock, shelves, interior lighting, electrical components, cabinet components, and refrigeration system are inspected for proper operation and physical condition.

Worn or defective components are repaired or replaced as necessary during the refurbishment process. The interior, shelving, glass door, and exterior cabinet are also thoroughly cleaned before the refrigerator is released for shipment.

Customers with specific temperature-testing or documentation requirements are encouraged to discuss those requirements with American Instrument Exchange before shipment. When practical, our technicians can address application-specific testing requests as part of the refurbishment process.

This refurbished VWR laboratory refrigerator includes a 90-day warranty from American Instrument Exchange.

Shipping & Installation

The VWR GTVWG30CPGA is a full-size upright laboratory refrigerator. Customers should verify the dimensions of the individual unit before delivery and confirm adequate clearance through loading docks, doorways, hallways, elevators, and other areas along the delivery route.

The final installation location should provide adequate ventilation around the refrigerator and sufficient clearance for normal operation and service access. Laboratories should also verify the electrical requirements shown on the unit's data plate before installation.

After transportation and placement, the refrigerator should be allowed to stabilize as appropriate before being loaded with temperature-sensitive materials. Laboratories should confirm satisfactory operating temperature before transferring valuable inventory into the chamber.

American Instrument Exchange can arrange freight transportation throughout the United States and internationally. Customers requiring liftgate service, inside delivery, rigging, or other specialized transportation should discuss those requirements with AIE before shipment.
