Frequently Asked Questions
Which vials do these inserts fit?
They are designed for Globe Scientific Diamond Essentials cryogenic vials, snapping into the screw caps for both externally and internally threaded formats.

Yes. The polypropylene inserts are rated for cryogenic temperatures and perform reliably in -80°C and LN₂ vapor-phase storage when used with compatible Diamond Essentials caps.
Are the inserts sterile?
No. These cap inserts are supplied non-sterile. If sterility is required, integrate them into your established decontamination or autoclave-validated workflow with appropriate verification.
How many inserts come per pack?
Each color ships 500 per pack. All five colors share the same per-pack price, making it easy to standardize a color-coding scheme across multiple freezers.
