Media Room (LG 1.07)
This is located off the north corridor of the Blizard laboratories. The media room is a core facility available for use by all laboratory staff and is used mainly for the preparation of bacteriological media, solutions and buffers and the autoclaves are used for the steam sterilization of these materials as well as for equipment such as pipette tips and instruments.
This is a clean room and no infectious material of any description may be brought into this area.
The following equipment is available for use:
2 x top pan balances
1 x waterbath set at 50ºC
3 x Boxer bench top autoclaves*
2 x Priorclave floor-standing autoclaves*
1 x horizontal laminar flow cabinet
1 x drying cabinet
Autoclaves may be used for the sterilization of liquid and solid media, micropipette tips, filters, empty containers and a wide range of instruments. In this case the aim is to inactivate any contaminating organisms occurring on the surfaces or within the material, rendering it sterile.
Bench top autoclaves are available to use for media preparation and the sterilization of instruments and pipette tips.

- Press the ‘Start’ button
- When the sterilization cycle is complete:
- The chamber temp falls below 80ºC
- The ‘Thermal lock’ light goes out
- The ‘Finish’ light illuminates
N.B. Visor and gloves must be worn when opening and unloading autoclaves.
- Open the autoclave door:
