When purchasing a PCR system, the heating and cooling rates, temperature control accuracy and range, sample capacity and hot cover function are undoubtedly the key parameters that users are most concerned about.

When purchasing a PCR machine, you should pay attention to several key parameters:

1. Maximum (increase/decrease) temperature rate:

Key parameters that may affect the PCR reaction rate.

2. Temperature accuracy and uniformity:

Factors that may affect the accuracy of the PCR reaction.

3. Sample capacity:

Factors that affect the price of the PCR instrument.

4. Hot cover function:

The hot cover is steplessly adjustable and can be positioned at any angle to adapt to test tubes of different heights.

5. Others:

Such as power-off protection function, software function, display screen, etc.

In short, when purchasing a basic PCR machine, the first consideration is to ensure the needs of the experiment and pay attention to ensuring that the parameters required by the experiment can be completed. The second consideration is the power-off protection function, software function, adjustable hot cover function, etc., which can ensure that the experiment is completed more efficiently. Finally, price and after-sales service are also issues that need attention.
