MTC Bio's 5mL Screw-Cap MacroTubes™ take all of the conveniences of standard 15mL conical tubes and scales them down for space efficiency and decreased natural resource consumption. Useful from -86°C to 110°C, these tubes are a valuable resource for boiling and for sample preservation at very low temperatures. Choose from gamma sterilized racked packaging with attached caps or non-sterile bulk packaging with separate caps. The foam racks are similar to the packaging normally associated with 15mL tubes (upright with caps attached), but they require about 60% less storage space. • Compatible with standard equipment • Centrifuge at up to 25,000xg • RNase, DNase & pyrogen free • Unsurpassed Clarity • Dual graduations at every 0.2mL and 0.5mL
