Glass is generally considered safe for autoclaving. When autoclaving glass bottles and caps together, make sure the cap is loosened prior to sending the components to autoclave to prevent the bottles from exploding. . Many times an aluminum foil with autoclave tapes are placed to keep the inside of the bottle sterile. Autoclave tape will also .Then its to avoid having bottles explode because people over tightened lids before autoclaving or immediately after they are taken out of the autoclave. It's a very good practice when you have lots of people making media but not enough time to train everyone to use autoclaves appropriately.The boil-over effect, as it’s commonly known, is problematic because it causes the loss of liquids and because it creates a mess inside the autoclave. Obviously, no researcher enjoys cleaning up splattered hot liquid or exploded glassware at the end of a liquid cycle, which are both unpleasant and potentially dangerous. Don’t bother autoclaving sterile tips! If they come sterile and in a sealed pack, they are sterile; don’t beat a sterile horse. Use the autoclave’s dry setting. The dry cycle is very bad for liquids (the lower chamber pressure will boil off—and even boil over—some of your liquid volume), but great for producing (nearly) dry loads.
You don't need a lab full of fancy tools and glassware to do molecular biology. . Heat the narrow portion of the pipet about 2 inches from the tip. When it melts, gravity should take over, bending it down at a 70-90 degree angle. .sterilized in autoclave bags. As with glassware, cover the necks and tops of the flasks/bottles with aluminum foil.
