Medical Grade Polypropylene Screw Lips 2D Cryogenic Tubes For Science Lab

Description

Jian sample collection kit was developed and assembled specifically for harvesting, transporting, and briefly storing potentially contagious patient specimens containing total DNA/RNA such as whole blood, saliva, serum, body fluids, etc. Deactivating preservatives included in the kit's functions in preparing the samples for further investigations such as DNA extraction, PCR, and so on.

Features

Designed for storage of biological material, human or animal cells, at temperatures as low as -190°C.

The cap features a long skirt for one hand aseptic technique.

A super-fast thread design that allows tightening or removal with a mere 1-1/4" turn, and an inside thread design that will not contribute to possible contamination.

Tubes are provided with a white marking area for sample identification and can be color-coded by the use of Cryogenic Vials

Cryogenic Vials are compatible with most storage systems.

Vials are sterilized by gamma irradiation and are packaged in unique tempered-proof, resealable, safety lock bags of 100/pack or a case of 10 x 100 groups.

The closures and tubes are both manufactured of polypropylene having the same coefficient of expansion, which further enhances the leak-proof qualities of these vials at changing temperatures.

Advantages

Internally threaded cryogenic vials are now and again perceived to maintain a higher seal due to the reality that the outdoor dimensions of the cap and the vial are equal. This capability that beneath equal temperature the cap and the vial will have elevated the identical amount, for this reason making sure a higher seal. Additionally, internally threaded vials typically have a silicone seal that is perceived. Some cryogenic vial producers recommend that there is no bother immersing cultures into liquid nitrogen, but most researchers advocate in opposition to this practice. Although the great majority of vials do seal in liquid nitrogen, there is a conceivable hazard that the liquid ought to seep into the vial. If this occurs when the vial is warmed, the trapped liquid nitrogen swiftly turns into a gas, exploding the vial. It is consequently beneficial to shop cultures in the vapor layer above the liquid nitrogen. Here the cells will continue to be in the gorgeous temperature furnished that perfect strategies are utilized for the opening and closing of the liquid nitrogen storage system. Moreover, a device needs to be in location so that cultures can be without problems discovered in the freezer, limiting the time the freezer and cultures are disturbed.
