Ideal for the storage of biological materials, our polypropylene tube with high-density polyethylene (HDPE) cap has an incredibly secure 2-turn closure that includes an external thread. Specifically designed to remove the risk of trapping sample on the inner wall. The difference in hardness between the tube and cap coupled with the cap’s molded in sealing ring forms a leak resistant seal. These round-bottomed tubes have molded in locking bases that work best with the Stockwell, Simport, Corning, and Nunc Storage Racks. When used in appropriate storage racks, tubes are easily opened or closed with one-handed operation. Tubes are graduated in 0.5mL increments and have a frosted writing area. Non-sterile tubes are packaged separately from caps. Sterile tubes are packaged with caps on. Storage Vials Features: High Density Polyethylene (used for the cap) provides a softer surface that conforms to a harder material like polypropylene-copolymer (used for the tube) to increase the integrity of the seal. Internal sealing ring envelops the top of the tube to prevent liquid by-pass. External threads eliminate the problem of sample retention common to internally threaded tubes. Universal locks hold tubes securely allowing for one-handed operation. Round bottom design assists to maximize sample recovery. -

Molded from high quality medical polypropylene material, produced in a clean room, these premium cryo tubes withstand temperature low to -196°C under gaseous phase of liquid nitrogen. The special cap pf external thread design and with silicone rubber liner gasket eliminates the possibility of liquid leakage and cross-infection, greatly ensuring specimen safety. The cryo tubes feature large white writing surface for specimen identification, delivered with optional colorful inserts onto the tube caps for specimen differentiation. Features: Made of medical grade PP material, autoclavable, Withstands temperature from -196°C to 121°C with a maximum pressure tolerance of 95kPa, East-to-read printed graduations, deliver accurate measurement, Special cap design & silicone rubber liner gasket insure leakage-proof, Gamma sterile, DNase free, RNase free and Non-pyrogen. -
Precision-molded from premium-grade plastics and ideal for routine laboratory analysis and procedures. Our tubes are rigorously inspected by our Quality Assurance Department to ensure they surpass our exacting specifications. These tubes are ideal for a wide range of laboratory applications. They are available in several sizes, and from three materials, to meet a variety of needs. All of the tubes are plastic (polystyrene, polypropylene or polypropylene-copolymer), thus preventing the problem of broken glass. Polypropylene is chemically resistant, autoclavable and virtually unbreakable. Polystyrene is clear like glass. Note that caps are ordered separately. These tubes are not available sterile. -
