External-Thread Cryogenic Vial 4.0, -196 to 121 C (CAT#: STEM-AL-6971-ZJF)

The External-Thread Cryogenic Vial 4.0 is a laboratory tube for sample containment, processing, and storage. Its polymer construction uses the PP and PE materials identified in the source for routine laboratory handling and low-temperature storage. The tube format supports the nominal size and closure configuration identified for this product. Graduation markings and a writing area are provided where specified to support sample identification and volume reference. The stated temperature range supports use across cold-storage and heated processing conditions within the source limits. Centrifugal performance is included only where the source provides an RCF value that clearly corresponds to this tube size. The source specifies the tube as free of DNase, RNase, and pyrogens for contamination-sensitive workflows. It is suited to cryogenic sample storage in molecular biology, clinical research, sample preparation, and laboratory storage.
