Screw Cap Microcentrifuge Tubes | ||
Neptune™ brand screw cap microcentrifuge tubes with an O-ring seal cap ensure a positive leakproof seal, time after time, retaining sample integrity under even the most adverse conditions. They are ideal for freezer storage, centrifugation and they fit most standard microcentrifuge rotors. Cryotubes vs Standard Tubes Standard screw-cap tubes use neoprene O-rings and are designed for general laboratory use down to -80°C. Below this temperature the neoprene fails to offer an effective seal. Cryotubes and vials feature special thread designs, higher grade polymers, and silicone O-rings to ensure secure long term storage for your precious cell cultures. |

Tube are designed for the storage of biological material at temperatures as low as -190ºC, but should be stored in the gas phase of liquid nitrogen. The cap features a long skirt for one hand aseptic techniques, and our thread design allows tightening or removal with a mere 1 1/4 turn. A specially designed lip inside the cap ensures a leak-proof seal. The cap and tube are made of virgin polypropylene with matched thermal coefficients to further ensure leak proof performance.

Cryo Tubes | |
Biotix’s cryotubes offer significant advantages over traditional cryovial storage, and at a lower price! The smaller outside diameter and molded spin collar allows for use in standard microcentrifuge rotors, so you can spin, resuspend and freeze all in the same tube. You can store 100 tubes in the same space as 81 cryovials. Manufactured from virgin grade polypropylene with silicone O-rings to seal at all temperatures. Biotix’s cryotubes are not just another screw cap tube, but a revolutionary cryostorage solution. Where else can you get more for less?

Mini-tube System |
![]() |
This system provides you with pre-racked 1.1ml strip minitubes in standard 96-well format. This is an ideal system for microplate to tube transfer or manual to robotic process transfer. The Minitube System provides you with pre-racked 1.1ml, 8 strip minitubes; an ideal system for microplate to tube transfers or manual to robotic process transfer.
The system features a standard 8 x 12 format for convenient, multichannel pipetting, and the alpha-numeric labeled, non-reversing rack and lid ensure positive sample identification. Condensation rings above each tube minimize cross contamination between wells, and the system is completely autoclavable (except for optional mini-cap strips). The rack base is fully compatible with all popular robotic instruments. |
