PLUG, 12 mm, Red, Case 4000

Precision molded Virgin thermoplastic Chemically clean Made of either polystyrene or polypropylene, these tubes are ideal for use in bacteriology, RIA, coagulation and other routine laboratory procedures. No mold release agents are used that could cause errors and interferences in RIA tests. Precision molded with virgin thermoplastics ensures that the tubes are uniform in size and shape as well as being chemically clean and ready to use. Non-sterile. Polypropylene tubes (PP) are translucent and will withstand over 3000 g during centrifugation. They will also accept most common acids, solvents and alkalies at room temperature. They are almost unbreakable and can be sterilized at 120°C. Polystyrene tubes (PS) are transparent and will withstand centrifugation speeds up to 1400 g. Clear plastic guarantees no danger of glass activation during testing. Polystyrene will tolerate aqueous solutions, mild bases and weak acids, but not organic solvents, aromatic or chlorinated hydrocarbons and cannot be autoclaved.
