Cole Parmer Cryovial 4 ml Sterile Skirted Bottom 3 Packs with 50 Vials Each

Cole-Parmer Sterile Cryogenic Vials, 4.0 mL, Skirted Bottom, External Thread (04395-62) – 3 Packs of 50 Vials (150 Vials Total)

The Cole-Parmer Sterile Cryogenic Vials (04395-62) are ultra-low temperature bio-storage containers engineered for the safe preservation, transport, and archiving of biological specimens, tissue cultures, serum samples, and cellular lines. Manufactured from high-purity polypropylene, these 4.0 mL cryovials feature a self-standing skirted bottom design that enables easy single-handed operation on laboratory benches and work surfaces. Built to withstand extreme cryogenic storage conditions ranging from -196°C to +121°C (vapor phase liquid nitrogen down to autoclave cycles), each vial is certified leakproof at 95 kPa for compliant bio-transport. The innovative external thread closure utilizes a co-molded TPE seal to eliminate traditional silicone O-rings, drastically reducing contamination hazards. Supplied as 3 re-sealable bags containing 50 sterile vials each (150 vials total), this set includes printed 1D barcodes and white writing surfaces for precise inventory control.

Technical Performance & Structural Attributes

• Self-Standing Skirted Base: Interlocking skirted bottom stabilizes the vial on flat surfaces and fits standard cryogenic rack locking slots for convenient one-handed cap operation.
• Co-Molded Contamination-Free Cap Seal: Integrates a thermoplastic elastomer (TPE) sealing membrane directly into the polyethylene screw cap, eliminating loose silicone O-rings that can trap moisture or contaminants.
• High-Pressure Leakproof Certification: Tested and certified at 95 kPa pressure differential to meet international IATA/ICAO packaging standards for air transport of biological specimens.
• Extreme Cryogenic Stability: Formulated from pure virgin polypropylene matrix capable of enduring liquid nitrogen vapor phase temperatures without becoming brittle or cracking.
• Clear Volume Markings & Identification: Features high-contrast printed graduation lines, a large glare-free white writing patch, and a unique pre-printed 1D barcode on every vial.
