Three common types of gene amplification instruments

The three common types of gene amplification instruments are mainly used for scientific research and clinical gene amplification, qualitative PCR gene amplification, fluorescence/enzyme free endpoint quantitative DNA gene amplification, gene chip and other gene analysis applications gene amplification,
etc.

The following are the three common types of gene amplification instruments, I hope to help everyone
.

1.
Metal modular PCR gene amplification instrument This kind of amplification instrument can be used for DNA amplification in ordinary 0.
5ml tubes, thin-walled tubes and in situ DNA amplification.
Sample tube wells, using resistance heating, compressor cooling, semiconductor modulation temperature or electronic modulation temperature
.

The machine is small in size, fast in heating and cooling, accurate in sample base temperature, high in uniformity, high in automation, large in amplification program capacity, and large in number of samples to be tested
.

The operation is simple and convenient, the test results are stable and reliable, and it is suitable for use in large-scale comprehensive scientific research institutions or diagnostic and quarantine units
.

It is the most common PCR gene amplification instrument produced and used at home and abroad
.

2.
The airflow type PCR gene amplification instrument is mainly composed of a convection incubator (chassis), a hot air source, a cold air source, a controller, etc.
The sample tube is placed in the convection incubator, and the controller controls the hot air and heat radiation sources.
And a high-power fan to provide hot and cold air to change the temperature of the reaction tube
.

The cost of the amplification instrument is low, the whole system has no liquid flow, and the safety is high
.

 　　3.
Water bath type PCR gene amplification instrument This instrument has adjustable temperature, high constant temperature accuracy, uniform temperature, low price, and is suitable for basic laboratory use, but the mechanical arm is prone to failure, and the water in the water bath is easy to evaporate (covered with mineral oil) can prevent evaporation), the volume is larger
.

It is generally composed of three water baths with different temperatures and a robotic arm.
The sample tubes are immersed in the three water baths respectively to complete the three processes of denaturation, renaturation and extension.
The time the reaction tube stays in each tank and the movement between the tanks It is done by a microcomputer and its controlled robotic arm
.

In addition, there is a type of water bath type PCR instrument, which has only one fixed sample tank, and the water of different temperatures is pumped in or out through microcomputer control to achieve the purpose of temperature control to complete DNA amplification.
This type of PCR instrument is rarely used
.

 　　This article introduces three different types of gene amplification instruments, one is the metal modular PCR gene amplification instrument, the second is the airflow type PCR gene amplification instrument, and the third is the water bath type PCR gene amplification instrument.
You can meet your own needs.
To choose, I hope to help everyone
