SuperClear centrifuge tubes are available in 15mL or 50mL sizes that fit all popular centrifuges and storage racks. All printed tubes feature an extra large solvent resistant white labeling area and black graduations for use with clear or turbid samples. Both 15mL and 50mL tubes are available in patented Earth Friendly racks that can be labeled with popular lab markers. These clean coated paper racks can be folded and recycled with other cardboard materials. Caps are available in flat style that can be easily labeled and a plug style that resists leaking. Both styles can be closed with a quick 3/4 turn allowing one handed opening and closing. Our 15mL and 50mL SuperClear tubes are made from our special medical grade resins that have been formulated specially so they will not yellow after radiation sterilization. This allows you to spin these tubes up to 15,000 x g unlike tubes made with lower cost resins that can only spin to speeds under 10,000 x g. 15mL tubes are also available in clear polystyrene with molded external graduations. 50mL skirted freestanding tubes with molded external graduations are available for use when separate racks are unavailable. Sterile tubes are radiation sterilized to ensure non-cytotoxicity.
