VWR Signature Ultra-Low Temperature Freezers are a reliable and dependable addition to the VWR's line of scientific freezers and refrigerators. Combining top-notch and uncompromising quality with an affordable price, these laboratory freezers can fulfill your laboratory needs while still offering a great value for the money. Constructed for long-term performance, these VWR scientific freezers represent the leading choice of laboratory professionals for applications where temperature control is critical. The VWR Signature ULT Lab Freezer offers a microprocessor temperature control system that maintains constant freezer temperature and a sophisticated microprocessor monitor/alarm system.
The microprocessor temperature control system of the VWR Signature -86°C to -50°C Freezer can be set in 1° increments. LED indicates actual chamber temperature. VWR has designed the air-cooled, hermetically-sealed dual compressors to work in unison and cycle at the demand of the microprocessor temperature controller. The automatic voltage compensator detects line frequency, monitors incoming voltage, and adjusts compressor voltage to reduce wear and tear on the compressors of the VWR ULT Upright and Chest Freezers.
The microprocessor monitor/alarm system features audible and visual indicators to keep the operator informed of over-/under-temperature conditions, power failures, low battery, and door ajar. Modern design includes an easy-to-grasp handle for one-handed operation. Dual wheel, locking swivel casters allow mobility as well as secure positioning of the VWR Signature Ultra-Low Temp Laboratory Freezer. A hinged grille swings out, exposing the foam air filter for easy cleaning or replacement. Industrial-grade cabinets are constructed of high-quality, heavy-gauge, cold-rolled steel. The powder-coated finish is rust- and chip-resistant. RS-232 and 4-20mA analog outputs are standard on the VWR Signature Freezer. These freezers feature a triple-point silicone door gasket, three fixed stainless steel shelves, lockable casters, and a vacuum relief port for easy reentry following door closings. Acoustical mufflers and sound absorbing foam in the freezer base reduce the noise level in the lab. To reduce cold air loss, these ULT freezers feature four inner compartment doors. To keep your specimens adequately refrigerated for future tests, make sure they're housed safely in the VWR Signature Ultra Low Temp 86 to 50°C Freezer.
