National Scientific ClickSeal CY1700-BP Polypropylene High-Capacity Graduated MicroCentrifuge Tube, 1.7ml Capacity, Yellow (Case of 5000)

Higher-capacity ClickSeal microcentrifuge tubes became the industry standard because our caps "click" when sealed. Volumes of 0.65ml, 1.7ml and 2.0ml fit all popular microcentrifuge rotors. Writing surface on flat cap and side wall for quick sample ID. Unique side-gated mold design eliminates risk of glove or finger puncture caused by sharp bottom-gate protrusions on other tubes. Superior clarity and external graduations ensure accurate, reproducible lab results. Target syringe port is easily pierced for spill-free handling of hazardous substances. Withstands temperatures from +121°C to -80°C and an RCF of 27,000 x g with proper rotor support. Positive ClickSeal design allows repeated cap closures and eliminates pressure-induced popping of caps during incubation. All tubes available in natural polypropylene, in RainbowPacks of five transparent colors, or as packs of a single color including Amber. Tubes are also available bagged and radiation sterilized in small RadPacks.
