There are several key parameters you should be aware of when purchasing a PCR instrument:

1. Maximum (up/down) temperature rate: heating rate 4 ° C / s, cooling rate 3 ° C / s. (Critical parameters that may affect the rate of PCR reactions).


2, temperature accuracy and uniformity: temperature accuracy ≤ ± 0.2 ° C, temperature uniformity ≤ ± 0.3 ° C (may affect the accuracy of the PCR reaction).


3. Sample capacity: 96×0.2ml, 96×0.2ml+77×0.5ml (factors affecting the price of the PCR instrument).


4, hot cover function: stepless adjustable, can be positioned at any angle of the hot cover, can adapt to different height test tubes.

So how do you choose a satisfactory PCR?

First, when purchasing basic PCR, the primary consideration is to ensure the needs of the experiment, and to focus on ensuring that the parameters required for the experiment, such as temperature accuracy uniformity, rise/fall rate, and sample size, are completed.

Secondly, such as power-off protection function, software function, adjustable hot-cover function, etc., can make us experiment more efficiently.

Again, price and after-sales service are also issues that we need to pay attention to when purchasing PCR. Good after-sales will make us feel the guarantee of quality and service. It can bring great convenience to our work when the instrument needs to be repaired and maintained.
