Self-Standing Clear Polypropylene Cryovials with External Thread for Liquid Nitrogen Storage Plastic Product Lab Usage
These cryogenic vials, made from sterile, DNase/RNase-free polypropylene with a silicone-sealed screw cap, are designed for reliable long-term storage of cell cultures, bacteria, and other biological samples in research and general laboratory settings. Offering both external- and internal-thread cap options, multiple bottom designs, large writing surfaces, and molded graduations, they provide secure, contamination-free cryopreservation in liquid nitrogen vapor — though they must not be immersed in the liquid phase.
Features：
- PP Material with Silicone Seal: Manufactured from polypropylene (PP) with a silicone washer inside the cap, ensuring a complete leak-proof seal.
- External & Internal Thread Options: External-thread caps reduce contamination risk during sample handling; internal-thread caps provide superior sealing to minimize liquid nitrogen ingress, suitable for storage in the vapor phase of liquid nitrogen.
- Sterile & Nucleic Acid-Free: Pre-sterilized, DNase-free, RNase-free, and pyrogen-free, ensuring sample integrity for sensitive biological applications.
- Large Writing Area: Generous white labeling surface allows detailed sample information recording.
- Molded Volume Graduations: Embossed scale markings on the tube body enable easy volume observation.
- Multiple Bottom Designs: Available in self-standing, round-bottom, skirted (bracket) bottom, and star-shaped bottom options to suit different storage and handling needs.
- Color-Coded Caps: Multiple cap colors (red, blue, green, yellow, etc.) for quick sample identification and workflow organization.
- Various Capacities: Offered in a range of volumes to accommodate different sample storage requirements.
Applications：
- Cell Culture Cryopreservation: Ideal for freezing and storing cell cultures, cell lines, and other biological specimens.
- Microbial Sample Storage: Used for long-term preservation of bacteria, fungi, and other microbial strains.
- Biobanking & Sample Archiving: Suitable for storing biological samples in research institutions, clinical labs, and biorepositories.
- General Laboratory Use: Applied in scientific research and routine laboratory workflows requiring low-temperature sample storage.
- Liquid Nitrogen Vapor Storage: Designed for storage in the vapor phase of liquid nitrogen (note: not for immersion in the liquid phase).
