Diamond Essentials Cryogenic Vials, Sterile, External Thread, Self-Standing Conical Bottom — 1.0–5.0 mL, 500/Case
The Diamond Essentials Cryogenic Vials deliver secure low-temperature sample storage for cell line cryopreservation, biobanking, and long-term aliquot archiving. External threads keep the sealing surface clear of sample, while the attached screwcap reduces handling loss. Conical, self-standing geometry supports benchtop pipetting and reliable recovery of pelleted material.

Frequently Asked Questions
Are these cryogenic vials suitable for liquid nitrogen storage?
Yes. The polypropylene construction withstands ultra-low temperatures; for direct liquid-phase immersion, use the vials within an overwrap or sleeve to prevent nitrogen ingress. Vapor-phase storage is recommended for routine cryopreservation.
What is the advantage of external threads over internal threads?
External threads keep the sealing surface and gasket area outside the sample chamber, reducing contamination risk and easing cap-thread cleaning. They also support faster opening and closing during high-throughput aliquoting.
Do the vials stand upright without a rack?
Yes. The self-standing conical base lets vials remain upright on the bench for unattended pipetting, while the conical geometry concentrates pelleted material for full recovery.
Are these vials sold sterile and ready to use?
All four volumes are supplied sterile and individually sealed for immediate use, with 500 vials per case. Lot numbers on each case support documentation in regulated workflows.
