Space efficient Cryotubes

With the rapid pace of modern life science research, space efficiency should never be an after-thought. This is the reason CAPP Expell cryogenic tubes feature the external thread design. With a beautiful slim profile that fits in very compact freezer racks for cryo tubes, CAPP Expell cryogenic tubes offer space savings of up to 23% when used with CAPP Expell 10×10 plastic cryoboxes. When compared with the average external thread cryo tubes on the market, CAPP cryotubes give scientists 23% more space to store precious samples that could lead to groundbreaking discoveries.

Exceptionally thermostable Cryogenic Tubes

Crafted to withstand some of the harshest cryopreservation conditions, CAPP Expell cryogenic tubes are manufactured from premium quality, thermostable polypropylene. Leveraging CAPP’s manufacturing experience spanning several years, our world-class team was able to innovate and iterate with several polymers to create these cryogenic tubes with the perfect thermal balance. Expell cryo tubes are designed to withstand temperatures as low as -196°C without cracking. Additionally, CAPP cryotubes can be safely autoclaved at 121°C. That’s a thermal range of 317°C! No wonder we are so excited about these extraordinary cryogenic tubes.

Perfectly-sealed Cryo Tubes

CAPP Expell cryotubes also feature cap design with a a lip seal closure. This carefully machined external thread design allows CAPP Expell cryo tubes to be opened with not only one hand, but also with just half a turn. This design approach increases liquid transfer efficiency by a wide margin and allows for better handling of cryogenic tubes in one hand. The lip seal cap design of Expell cryo tubes also prevents overtightening of the lid while keeping the cryogenic tubes 100% leak-proof.

Extra-stable Cryotubes

Another feature that sets CAPP Expell cryotubes apart from the competition is the unique star-foot bottom. This well-engineered base gives CAPP cryotubes better stability on the workbench when compared with cryogenic tubes with standard bases. Additionally, the star-foot bottom allows users to open CAPP Expell cryo tubes without removing them from select CAPP cryoboxes. What’s great about this feature of CAPP cryo tubes is that users spend less time retrieving stored samples from their cryogenic tubes, allowing them to invest that time in the more fun parts of research.

Cryotubes with colored cap inserts

To add a touch of functionality (and brilliance) CAPP Expell cryotubes feature colored cap inserts that fit snugly of the top of the cryo tubes. With the colored cap inserts, researchers can easily categorize the samples stored in their cryo tubes with visual cues that are both fun and easy to remember. The cap inserts for CAPP Expell cryotubes come in five color variants that are easy to recognize at a glance. With red, blue, white, yellow, and green options, selecting the correct cryotubes is now a breeze!

Cryogenic Tubes with easy-to-read labels

Designed to minimize eye strain, CAPP Expell cryo tubes feature molded graduation marks and a large labeling area. The molded graduation marks on Expell cryotubes remain clear and highly visible under a variety of lighting conditions. This helps users to easily monitor liquid volumes as they pipette samples into, and out of the CAPP Expell cryo tubes. A large writing area with a white background allows users to easily label their cryogenic tubes for better sample indexing (not incl. with 0.5mL cryotubes). The white background also provides excellent contrast for better readability of custom labels on the cryo tubes.
