Chemical additives in steam will attack transparent plastics and cause a permanently glazed surface after autoclaving. Some transparent plastics may absorb minute amounts of water vapor and appear cloudy after autoclaving. The clouding will disappear as the plastic dries. Clearing may be accelerated in a drying oven at 110°C.
Consult the autoclave manual for assistance in choosing the correct cycle parameters. Autoclave manuals should be stored near the autoclave. Do not attempt to open the autoclave door once the cycle has started. As previously mentioned, autoclave doors feature a mechanical locking mechanism that can be damaged by extreme force.
For secondary containment, use autoclave trays made out of polypropylene, polycarbonate or stainless steel. The trays should have a solid bottom and sides to contain the contents and catch spills. Choose appropriate cycle for the material. Incorrect selection of cycle may damage the autoclave, cause liquid to boil over or bottles to break. Turn Off the Oven and Let the Bottles Cool: Once the bottles are dry, turn off the oven and let the bottles cool inside for a while.

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.
Autoclave your medium for 25 minutes. After autoclaving, you can, of course, store the medium-agar mix in a toughened glass bottle then melt it in a microwave or water bath when needed. Make sure you use toughened glass bottles, or disaster can strike. Remember to use heat-resistant gloves when handling hot medium straight out of the autoclave. 3.After washing, place flasks into a stainless steel tray. Put the dry lids back onto the flasks. Place a new strip of autoclave tape on the tray. The clean flasks are now ready for sterilization. Autoclave on gravity cycle for 45 or 60 minutes. If necessary, place trays of flasks in an oven to dry or air dry. Then, place in the black "sterile .
Nonhazardous dry goods: 30 minutes of sterilization plus 20 minutes of drying time. Dry time may need to be increased for enclosed items such as pipette tips or bottles with lids. Liquids (add 10–20 minutes for crowded items): Less than 500 milliliters (ml): 30 minutes; 500 ml – 1 liter: 40 minutes; 2–4 liters: 55 minutes The number of autoclave cycles that a product can be subjected to depends on the type of autoclavable glass bottle, with soda lime bottles and plastic-coated bottles able to withstand fewer autoclave cycles than uncoated borosilicate 3.3 laboratory bottles. Heat the bottles: Once the oven has preheated, place the baking sheet in the oven. Allow the bottles to heat for at least 1 hour. Cool down: After an hour, turn off the oven but do not remove the bottles immediately. Let them cool down inside the oven to prevent them from cracking due to sudden temperature changes.
1) Is it safe to autoclave all types of laboratory glass bottles? Before autoclaving lab bottles, it’s important to consider the suitability of different glass and bottle types. Borosilicate glass bottles are safe to autoclave as the material has a very good resistance to thermal shock. There is a much higher risk of breakage when autoclaving .
When autoclaving large vessels, leave the covers off and don’t stack other items on top of them. Pipette cans should be loosely capped and dried in an oven after autoclaving, if necessary. The recording and/or indicating thermometer on the autoclave must be checked annually for calibration by a technician certified by the manufacturer.Autoclaving liquids presents some unique challenges. Liquids take longer to sterilize than other media since liquids have a high heat capacity. As opposed to solids, liquids take a lot longer to heat up and cool down, and the total cycle time is increased dramatically as a result. .

Tightening caps on hot bottles will lead to distortion of the bottle as the content cools down.Autoclaving is the most effective and reliable means of sterilizing laboratory materials. Autoclaving sterilizes material using saturated steam under pressure (“moist heat”). Due to the use of pressure, steam and high temperatures, there is significant risk for injury, so it's important for individuals to be properly trained on operational procedures.
Secure glass bottle caps before beginning the autoclaving process. Loose caps could cause glass bottles to explode under the pressure. If possible, aim to use borosilicate glassware. It has silica and boron trioxide as the main glass-forming constituents and is thought to be able to withstand the high pressure of autoclaving better than other . Before you autoclave plastic bottles it is advisable to use some form of indicator to demonstrate that the correct temperature has been consistently achieved.

Also, when I didn't have a dishwasher to use, I'd sanitize with StarSan in a Sulfiter and dry on a clean bottle tree.
Autoclaving for 60–90 min at 121 °C (15 psi), depending on the loading conditions, to achieve a waste temperature of at least 115 °C for 20 min is recommended. Effective autoclaving will depend on time, temperature, and steam penetration. Tubes, bottles, flasks, and bags should be loosely closed to allow steam penetration.
