The PCR process (Polymerase chain reaction) is a very delicate technique in which the scientific manages to get a few copies of the same DNA sample, generating a sequence of the same DNA. Nowadays this process is very common and necessary in many fields, such as research laboratories, diagnosis and monitoring of hereditary diseases, DNA profiling in forensic science and more. Kalstein products is aware of the importance of having good quality PCR tubes, so that you can rely 100% on the sample you are testing.
These are robust virgin polypropylene strip PCR tubes, which is the perfect material for this type of uses. Virgin polypropylene is a thermoplastic resistant to high temperatures due to its 130 degrees Celsius melting point and its high resistance in general. On the other hand, the plastic these PCR tubes are made from, is clearer so that is not going to be a problem for those who handle samples and have to run them through inspections in a laboratory.
The design in these 0.2ml PCR tubes allows them to fit in all commonly used thermal cyclers, so that is not going to be a problem for you. They also have ultra-thin walls, which allows precise thermal transfer.
There are two models of these strip PCR tubes. One is with a dome cap and the other one is witha flat cap. Both of those models come with a beveled edge, which makes it more comfortable for opening and closing. To avoid any evaporations during storage thetubes have a precise lid sealing.
Another great feature is that they are autoclavable, in case you need to sterilize them. Nevertheless, you also have the option to acquire RNase, DNase, DNA and Pyrogen sterilized microtubes so that you can use them without having to do that sterilizing process. The way to get it is by making a special request.
As you already know, there are two different models of these 0.2ml PCR tubes. The first model is the one with the dome cap, which comes in a package of 125 strips per bag and 1250 bags per case. In the case of the flat cap model, they also come distributed in that way, 125 strips per bag and 1250 bags per case. All of these three models come with a natural color.
