Slide box and Autoclave
Slide box:
Plastic
or wooden box with lid and slots to take up to 50 or more slides. Needed for
storing control and teaching slide preparation.
Ph meter : Hanna ph 3 meter /Hanna batteries ph
meter.
Criteria:
1.Low cost , electronic
,hand held waterproof meter .
2.Can calculate a range
of ph 0.1 -14 and resolution of Ph 0.1 with automatic calibration and
temperature compensation.
Care of Ph meter:
1.Do not keep it in high
temperature.
2.Do not keep it in the
moisture.
3.Handle carefully .Do
not fall it any place.
pH paper:
1.These are suitable in
the small district laboratories.
2.They can not measure
accurate Ph
3.They check the pH by
staining techniques,
4.There neutral litmus
papers that turns red when a reaction is acid and blue when alkaline.
Autoclave:
Principle: In autoclave
pressure is used to produce high temperature steam to achieve sterilization ,
Temperature increases with pressure, At a pressure of 15 Ibo/2 inch.
The temperature of the
saturated steam rises to 121°C and 15 -20 minutes time is required.
Precautions: Both the
temperature and holding time must be correct.
For temperature: Obtain the
correct temperature for sterilization. All the air must be removed form the
autoclave.
For autoclave is used for:
1.To sterilize reusable needles . syringes, lancet, specimen containers,
tubes ,pipettes, petridishes and other articles that need to sterile before
use. Items made from glass, metal and plastic such as nylon, co-polymer can be autoclaves.
2.Decontaminating specimens and other infectious waster prior
