Whether you are helping to solve complex biological problems, investigating the causes of diseases or finding potential new cures, you need consumables that meet your workflow needs.

For virtually effortless sealing, OptiSeal tubes offer an excellent option. You simply insert the tube plug and press, and an O-ring seals securely against the tube's inner surface. During centrifugation, the combination of g-force and hydrostatic pressure ensures an effective seal. Engineered for reliability, there are no tools or mechanical parts to maintain. Finger pressure is all that is needed.
