1.8 mL Cryovials in Pakistan

1.8 mL Cryovials (Cryogenic Vials) are high-precision, ultra-low temperature laboratory storage tubes engineered for the safe preservation of biological samples, cellular suspensions, serum, and genetic material. Manufactured from medical-grade, highly transparent polypropylene (PP), these vials feature a leak-proof screw cap with an integrated silicone O-ring, crisp printed graduations, and a white writing field for labeling. Essential for biobanks, cell culture laboratories, clinical diagnostic centers, and university research institutes across Pakistan operating in cryogenic and deep-freeze environments.

1.8 mL Cryovials – Ultra-Low Temperature Sample Storage

1.8 mL Cryovials provide a reliable, leak-proof, and contamination-free solution for the long-term preservation of biological specimens in liquid nitrogen vapor phase and ultra-low temperature freezers. Precision-molded from specialized low-binding polypropylene, these vials are engineered to withstand extreme thermal contraction and expansion without cracking or losing seal integrity. Available in both internal thread design (with silicone washer for space-saving storage) and external thread design (to minimize contamination during capping), they feature a self-standing star-foot base that locks into specialized laboratory racks for easy single-handed operation.

Key Applications:

Cryogenic Sample Preservation: Ideal for long-term storage of cell lines, stem cells, microbiological cultures, viral stocks, and blood components in deep freezers and liquid nitrogen containers.
Molecular & Genomic Banking: Widely used for archiving DNA, RNA, tissue extracts, and master reagent stocks across biobanks and research centers in Pakistan.
Clinical Diagnostic Storage: Essential for storing control sera, clinical specimens, and reference standards in medical pathology laboratories.
