• In polypropylene: autoclavables, can be used from -80 °C to +122 °C, centrifugal up to 3000 RCF • Made of polystyrene: can be used from -40 °C to +90 °C, centrifugal up to 1500 RCF
• Tubes certified as sterile, non-pyrogenic and non-cytotoxic (except ref. 352075 and 352076) • Medical grade packaging guarantees perfect sterility • Very precise printed graduations and large labelling area • Excellent optical clarity • Low protein adsorption on the walls of the clarified polypropylene tubes • High resistance to extreme physico-chemical conditions
Centrifugation: • 50 ml clarified polypropylene: 16 000 g • 15 ml clarified polypropylene: 12 000 g • 15 ml polystyrene: 1800 g • 175 ml and 225 ml polypropylene: 7500 g
Tubes with round bottom made from polystyrene treated for cell cultures (Nunclon).
Three tube models: • with screw cap; • with tight-fit cap; • with flat area of 5.5 cm² and screw cap. It is possible to place a 10 x 20 mm glass slide on the flat area inside the tube.
• Single use • Polystyrene or polypropylene • For RIA, bacteriology, coagulation • The polypropylene tubes can be autoclaved at 120 °C and can be centrifuged at 3 000 g • The transparent polystyrene tubes can handle centrifugations at 1 400 g • The 039384 tubes are made from polypropylene with low surface retention, enabling maximum sample recovery • The tubes packaged in groups of 125 are presented in containers with all of the tubes oriented in the same direction
• Polypropylene (raw material as per USP class 6); HDPE cap • Free of DNase, RNase, human DNA and pyrogens • Cap with flattened and grooved sides • High quality biopolypropylene, produced from second generation recycled raw materials, in this case derived solely from waste and residues (e.g. vegetable oil production and used cooking oil)
