Horizontal Electrophoresis System, 20 cm x 25 cm
ClearSeal™ Generic Screw Cap Microcentrifuge Tubes
Sterile, Leak-Proof, Ultra-Clear.
ClearSeal™ Generic Screw Cap Microcentrifuge Tubes are designed for superior sample protection and storage. Made from ultra-clear polypropylene, these sterile microcentrifuge tubes feature pre-assembled screw caps with secure silicone O-rings, ensuring a 100% leak-proof seal under extreme conditions—from
-86°C to +121°C.
Available in multiple sizes and configurations, including a convenient loop-cap option on the 2.0 mL size, ClearSeal™ tubes meet the needs of both research laboratories and diagnostic/reagent packaging applications. Each tube is certified RNase, DNase, and pyrogen-free, making them ideal for sensitive biological samples.
ClearSeal™ microtubes can be centrifuged at up to 22,000 x g* and are packaged in resealable bags of 50 for ease of use and contamination control. Available in single-color cap packs of 1000.
