Whether it is storing biological samples, reagents, vaccines or experimental materials, used lab freezer can meet the strict low-temperature requirements of laboratory work, and has become an indispensable equipment for many small and medium-sized scientific research institutions and enterprises with limited budgets.
Common Models and Parameters
There are various models of used lab freezer on the market, and each model has different parameter configurations to meet different storage needs. The following are several common models and their core parameters:
1. Chest-type used lab freezer: The volume is usually between 100L and 500L, the temperature range is -20℃ to -40℃, and it is suitable for storing large-volume samples such as blood products and cell cultures. The inner tank of this type of used lab freezer is usually made of stainless steel, which has good corrosion resistance and easy cleaning performance.
2. Upright used lab freezer: The volume ranges from 200L to 800L, the temperature can reach -86℃ at the lowest, and it is equipped with layered storage racks, which is convenient for classified storage of different samples. This type of used lab freezer is often used in pharmaceutical research and genetic engineering laboratories, which need to store a variety of small-volume reagents and samples.

The insulation layer of this type of used lab freezer is thicker, and it is equipped with an intelligent temperature control system to ensure the stability of the internal temperature.
Product Details and Features
When selecting a used lab freezer, in addition to paying attention to the model and parameters, it is also necessary to understand the details of the equipment to ensure its performance and reliability.
First of all, the insulation performance of used lab freezer is crucial. The high-quality used lab freezer is usually equipped with a polyurethane foam insulation layer with a thickness of 50mm to 100mm, which can effectively reduce cold air loss and maintain a stable internal temperature. At the same time, the door seal of used lab freezer needs to be intact, without cracks or aging, to avoid cold air leakage caused by poor sealing.
Secondly, the temperature control system of used lab freezer is the core component. Most qualified used lab freezer are equipped with digital display temperature controllers, which can accurately display and adjust the internal temperature, with an error of no more than ±1℃. Some high-end used lab freezer also have temperature alarm functions. When the internal temperature exceeds the set range, they will send out sound and light alarms in time to remind the staff to deal with it, avoiding sample damage caused by abnormal temperature.
In addition, the compressor of used lab freezer is also a key part affecting its performance. The used lab freezer with well-maintained compressors usually uses imported brand compressors, which have the characteristics of low noise, low energy consumption and long service life. At the same time, the condenser and evaporator of used lab freezer need to be cleaned regularly to ensure good heat dissipation effect and avoid excessive energy consumption caused by dust accumulation.
Finally, the internal structure of used lab freezer is also worthy of attention. The inner tank of high-quality used lab freezer is made of food-grade stainless steel, which is not only corrosion-resistant but also easy to clean, avoiding cross-contamination between samples. The internal storage racks are usually adjustable, which can be adjusted according to the size and quantity of samples to improve the utilization rate of storage space.
Core Advantages of used lab freezer
