HERE IS AN INTERESTING STEP TO AUDIT YOUR AUTOCLAVE'S FUNCTIONING..SPECIALLY FOR STUDENTS..
U ALL KNOW that autoclave is a device which is used for sterlization(heat) at laboratory as well as industrial levels.This mode of Sterlization involves a heating ,a cooling, and a HOLDING period.The temprature and pressure during holding is 121 degrees centigrade and 121 psi .
BUT, are u sure that the sterlization u perform at your laboratories is good enough??..
Here is a checking trick for it. i came to know about it during my training at CENRAL RESEARCH INSTITUTE ,KASAULI.
We can use INDICATOR TAPES while autoclaving process.chemical indicator tapes have certain chemicals which undergo a specific colour change only if right temprature and pressure conditions are attained for the required holding period( 15 minutes)..
This information may not be that good but it was something new which triggered an engineering feel within me, and to the extent i should analyze things going around.
