T309 Series: 4.0ml Self-Standing
Cap Design: Lip Seal Design
Tube Design: Self-Standing with graduations
Designed for storing cells, blood, serum and other biological fluids at temperatures as low as -196 °C, these sturdy polypropylene vials offer a high level of chemical resistance but should be used only in the gas phase of liquid nitrogen.
The cap features a long skirt for one hand aseptic methods and an inside thread design that will not contribute to possible contamination. A specially designed lip inside the cap ensures a leakproof seal even at very low temperatures. Closures and tubes are both made of polypropylene having the same coefficient of expansion, which further enhances the leakproof qualities of these vials at various temperatures. 12.5x77mm
Tubes are provided with a white marking area for sample identification and can be color coded by the use of a CAPINSERT (Series T312). T309-2 can be centrifuged up to 17,000g. Vials are sterilized by gamma radiation and are packaged in unique tamperproof, resealable, safety-lock bags of 100. Autoclavable. Certified RNase-, DNase-, Pyrogen- and DNA-free
