Such a good freeze-thaw bag, where there is no reason not to choose

Freeze-thaw bag is a cost-effective cell cryopreservation bag, is an important medium for the storage of biological agents in clinical and scientific research applications, such as cells, tissues and other biological products, usually need to be stored at -150 °C and below temperature to ensure its biological activity
.

The bags have received marketing permission from the FDA and are used to protect, store and freeze cells and tissues
.

Use inert FEP entirely, with no plasticizers or chemical residues in the bag to immerse or alter delicate cell cultures
.

Specific characteristics of freeze-thaw bags: 1, inert: FEP is chemically and biologically inert, so the bag will not change the culture or medium
.

FEP neither binds to any element nor places any of its own components in
a solution contained in a cell cryopreservation bag.

2, breathability: FEP membrane is breathable, oxygen, carbon dioxide and nitrogen gas transmission rate has been announced
.

However, FEP is practically impermeable, so the water loss from cell culture is negligible
.

Humidified incubators – potential sources of mold and contamination – are not required
.

3, sealing: cryopreservation bags are closed systems, so the possibility of contamination is greatly reduced
.

4.
Optics: Cryopreservation bags have an optical transmittance greater than 95
%.

Observing cell cultures under a microscope is easy and can be performed without risking contaminating the
sample.

5, heat: cryopreservation bag can be used as a freezer bag, and remain flexible, at low temperature storage (-196ºC) to high pressure (+137ºC) temperature, the mechanical strength will not be significantly reduced
.

6, safety features: each freeze-thaw bag has a hanger hole, so that it is convenient for the bag to hook, each bag is equipped with a needleless adapter to reduce the chance of
needle puncture.
