Intended use

For preparation, centrifugation and storage of photosensitive biological samples: RNA, enzymatic reagents, fluorophores, vitamins and any compound that degrades under UV-visible light. Rated to 20000 xg — suitable for high-speed centrifugation protocols without switching tubes between steps.

Standard use in molecular biology, biochemistry, microbiology and clinical diagnostics laboratories.

Sterilisation and traceability

The sterile version is sterilised by gamma irradiation. Supplied in a resealable bag to maintain sterility until point of use. Sterilisation certificate available for free download — useful where protocols or audits require documentation.

Conical no-skirt base

The conical no-skirt base allows easier recovery of small pellets — sediment concentrates at the tip and the pipette reaches it unobstructed. Without the skirt, the tube seats directly in the rotor with no positional adjustment required.
