Although many laboratories use typical consumer refrigerator/freezer units for storing samples and chemical supplies, there are a number of instances in which a unit designed specifically for the lab environment is necessary; for example, flammable substances such as solvents can ignite if a kitchen-designed fridge or freezer generates a spark when switching on. Laboratory refrigerator freezers incorporate design and technology elements that facilitate lab work. For example, manual defrosting helps the user control freezer burn, dehydration, and improper thawing. A laboratory refrigerator freezer can also come with sophisticated digital temperature control mechanisms. This permits user-defined temperature setpoints, complemented by alarms that indicate when the unit is over or under temperature, or if the door is ajar. These laboratory refrigerator freezers are generally more durable than their consumer counterparts, and meet stringent regulatory requirements such as OSHA CFR1910.308.

Space-saving compact cabinet design provides two storage temperatures in a single footprint. Microprocessor controller with digital temperature display and alarms maintains precise temperature, adjustable 2°C to 14°C in refrigerator, -20°C to -30°C in freezer. Separate refrigeration systems and compressors allow differential control of individual refrigerator and freezer compartments unlike commercial combination refrigerator/freezer that rely on one refrigeration system (one compressor) to maintain temperature in both chambers. Temperature in the refrigerator is maintained with a forced air system, plus a unique cycle defrost only initiates as required and maintains internal temperature uniformity without fluctuations. Freezer chamber utilizes a cold wall design with manual defrost....
