Celltreat Sure Cap Polystyrene 15 mL Centrifuge Tubes contain a compressible liner on the inside of the cap that creates a better seal than non-lined caps of standard 15 mL conical tubes.
Ideal for use with alcohol, which can leak from unlined caps, for example. Polystyrene conical tubes are optically clear, unlike standard polypropylene conical tubes, but are not as strong, so they withstand less Relative Centrifugal Force (RCF=3,000 x g).
Celltreat Sure Cap polystyrene 15 mL centrifuge tubes have excellent clarity. They have green flat top caps made of HDPE.
No printed graduations; graduation are molded into the tube at 0.5 mL increments. No white marking area.
Sterile. Bulk-packed in zip-close bags, 25 tubes/bag, 20 bags/case. 500/case.
