Color-Coded Cap Inserts for CryoCLEAR Vials — 9 Colors, 100/Bag & 500/Bag
These Cap Inserts for CryoCLEAR Vials snap into standard CryoCLEAR screw caps to add instant, at-a-glance color coding for cryogenic sample identification. Labs use them to separate aliquots by study arm, distinguish cell lines in shared LN2 tanks, and accelerate retrieval from crowded freezer boxes. Available in nine distinct colors across two pack sizes.

Frequently Asked Questions
Do these inserts fit all CryoCLEAR vials?
Yes. They are engineered to snap into standard Globe Scientific CryoCLEAR screw-cap vials, providing a secure color-coded fit without affecting the seal.
Can the inserts withstand liquid nitrogen storage?
The polypropylene construction is suited to cryogenic temperatures used in LN2 and ultra-low freezer storage when properly seated in the cap.
What is the difference between the base and -100 SKUs?
Base SKUs (e.g., 30079Y) are supplied 500 per bag; the -100 SKUs (e.g., 30079Y-100) are supplied 100 per bag.
Are the inserts sterile?
No. These cap inserts are supplied non-sterile, intended as identification accessories rather than sample-contact components.
