Do you know the difference between them?

There are two types of freeze-thaw tubes: internal rotation type and external rotation type. Do you know the difference between them?

Which is better? Let’s take a look.

The inner screw cap of the cryopreservation tube is used to freeze biological samples with liquid nitrogen. The silicone pad at the nozzle of the tube enhances the sealing of the cryopreservation tube, which can effectively prevent the infiltration of liquid nitrogen;

   The external rotation cryopreservation tube is used to freeze samples in the refrigerator. The screw cap of the external rotation cap can reduce the pollution probability when handling samples
The external rotation is more likely to pollute than the internal rotation, and it is not easy to operate, but it is also not accurate. Look at the operation. The internal rotation liquid is easy to get onto the cover thread. As for the tube explosion, the internal rotation tube is really easy to explode (but also the probability is very small), so please operate with caution.

   Now let’s know the characteristics of the inner screw cap of the cryopreservation tube

1. The inner screw cap of the freezing tube is designed for freezing samples, and the threaded cap of the outer screw cap can reduce the pollution probability when handling samples.
2. The inner rotation freezing tube is designed for freezing samples in liquid nitrogen phase, and the silica gel pad at the nozzle enhances the sealing of the freezing tube.
3. The line of pipe cap is easy to rotate the cover.
4. The pipe cap and pipe body are produced with PP raw materials of the same batch and model, so the same expansion coefficient ensures that they can be sealed at any temperature.
5. Large marking area is convenient for writing.
6. The tube is extremely transparent and easy to observe the sample.
7. The round bottom design is convenient for pouring liquid and reducing residue.

 

   These are the knowledge points about the inner screw cap of the cryopreservation tube. I hope the above content can help you. Thank you for your watching and support. More information will be sorted out for you later. Please pay attention to our website update.
