The Cryogenic Freezing Container from Maccx is made of Polycarbonate Jar with HDPE(high-density polyethylene) Closure, could withstand 12 to 18 tubes under -80℃(-176℉) mechanical freezer. Provides the critical, repeatable -1°C/minute cooling rate required for successful cell cryopreservation and recovery.

Safer and more convenient to use, no water absorption, no influence on the label, no fouling of the handwritten content on the tubes.

Prior to inserting vials, fill with 100% isopropyl alcohol into the jar.
Once the samples' been inserted, the jar should be placed in a -80℃(-176℉) mechanical freezer.

Attention: store at room temperature when not in use. Replace alcohol after fifth use.
