In the daily operation of the laboratory, this manual aims to provide a practical guide for laboratory users on how to scientifically and reasonably choose a refrigerator that meets the laboratory's needs. From requirement analysis to technical matching, from brand evaluation to after-sales support, the key links of refrigerator selection are systematically sorted out to assist users in making decisions.

1、 Requirement analysis

1Temperature range

Clarify the temperature range required for the experiment（as-20°Cto-80°C）Ensure that the freezer covers this area.

Biological samples are required-80°CUltra low temperature storage, chemical experiments may require lower temperatures.

2Sample type and quantity

Biological samples require long-term stable low temperature, while chemical samples may require rapid cooling.

The number of samples determines the capacity of the freezer, and redundant space needs to be reserved.

3Frequency of use

High frequency use requires the selection of models with strong durability and fast start-up, while low-frequency use can be appropriately reduced in configuration.

2、 Technical parameters

1Cooling capacity and efficiency

The cooling capacity should avoid overload or waste.

Prioritize selecting models with energy efficiency ratios to reduce long-term operating costs.

2Temperature fluctuations

Optimal model temperature fluctuation≤±1°C.

3Cooling speed

Rapid cooling can shorten the experimental cycle, and attention should be paid to the cooling rate.

threeEnvironment and Safety

1Environmental adaptability

Due to limited laboratory space, air-cooled options are available without the need for a cooling water tower;Water cooling is available for better cooling effect due to sufficient space.

2Safety performance

It is necessary to have safety devices such as overload protection, high and low voltage protection, and antifreeze protection.

fourBrand and after-sales service

1Brand reputation

Choose a brand to ensure reliable equipment performance.

2After sales service

A comprehensive after-sales service system, including rapid response, regular maintenance, and parts supply.

fiveBudget and Cost

1Initial investment

Choose cost-effectiveness based on budgetsuitableThe model should avoid excessive pursuit of high configuration.

2Operating costs

Consider long-term costs such as energy consumption and maintenance expenses, and choose models with high energy efficiency.
