Frequently Asked Questions
Which cryogenic vials do these inserts fit?
They are designed for Globe Scientific cryogenic vials that use O-ring screw caps. The insert press-fits into the cap top, so confirm your vials use the matching O-ring closure format before ordering.
Will the inserts survive liquid nitrogen and ultra-low freezers?
Yes. The polypropylene inserts are intended for cryogenic storage in -80°C freezers and LN2 systems, holding their color and fit across repeated freeze cycles.
How many inserts come in a pack?
Each pack contains 500 inserts of a single color, priced at $31.00 per pack. Order multiple colors to build a complete coding scheme.
Are the inserts sterile?
No, the inserts are supplied non-sterile. They serve as identification accessories on the cap exterior and do not contact the sample.
