Sterilization of Glassware, Equipments and Culture Media
The thoroughly washed glassware and equipments and carefully prepared culture media are sterilized by heat, steam or millipore filter paper (Table 6.4 ). The sterilized materials are removed when temperature cools down and used according to procedure adopted. For detailed description see In Vitro Culture Techniques: The Biotechnological Principles.

Table 6.4. Sterilization of glassware and equipments.

  Sterilization Items
Apparatus containing glass and silicon tubing, disposable tips for micropipettes, dispensor tubing for pupet, glass bottles with screw caps, magnetic stirrer bars, screw caps, silicon tubing, topper-rubber, silicon, millipore filters, etc
  Dry heat** Glassware, glass coverslips, glass slides, instruments, Pasteur pipettes, pipettes, test tubes, etc.
*15 lb/in2 (=121°C) for 20 minutes; **160°C/ 1 hour.
