Capp Expell cryotubes are designed with a focus on the best user experience and convenience. Featured with single-handed QuickSealTM closure, the external thread design allows tightening or removal with only half a turn. Simultaneously, the Lip Seal Cap Design of Expell cryotubes, ensures 100% leak proof closure without the use of internal cap O-rings. Capp Expell cryogenic tubes have a unique streamlined design with absolutely no edges on the lid or between the lid and the tube. This revolutionary streamlined design makes Capp Expell cryotubes, one of the only external thread cryo tubes that can be stored on cryo boxes with 10x10 dividers. The majority of other external thread cryogenic tubes on the market are only suitable for storage on 9x9 boxes. With Capp Expell cryotubes, you save up to 23% of your storage capacity compared to the conventional external thread cryo tubes. On top of that, Capp Expell cryogenic tubes are also compatible with common working stations on the market.
Capp's unique portfolio of cryotubes covers 5 volumes: 0.5mL, 1.0mL, 2.0mL, 4.0mL and 5.0mL. With Capp Expell cryo tubes of 0.5mL you can efficiently store even the very small samples, as these are the smallest cryotubes available on the market. Additionally, when working with Capp 0.5mL cryogenic tubes, you can store two 10x10 racks on top of each other, doubling the storage capacity of your freezer. Both the caps and the cryo tubes are made of specially formulated polypropylene, having the same coefficient of expansion and therefore enhancing the leak proof qualities at various temperatures. Expell cryo tubes come packed in re-sealable stand-up pouches, saving benchtop space.
