Description Heavy Duty Pyrex Glass Test Tubes Can take repeated sterilization in dry heat ovens or autoclaves Convenient way of holding tweezers for sterilization Be sure to have plenty of corks or caps on hand (sold separately). Pro Tip : When sterilizing, it is important to make sure each instrument is properly contained in its own environment to keep it sterile until it needs to be used. Consider test tubes for sterilizing tweezers, comedone extractors or other long, thin instruments. These test tubes can be used in autoclave or dry heat so long as the proper test tube cap is used. For autoclave users, feel free to use our plastic caps or corks. If you use dry heat, please only reach for corks, as plastic caps will surely melt and make a big mess in your sterilizer! When loading your sterilizer, it is pertinent all of your tubes, bags or pouches have enough room to “breathe” in order to sterilize properly. Looking for a way to store your test tubes? Check out this plastic test tube rack. Whether your tubes are empty or contain sterilized tweezers, this rack will hold them up right until you are ready to use them. Conveniently holds up to 60 test tubes. SKU: T14957, C07791E, C1495791
