This SOP is applicable for the calibration procedure of BOD/ bacteriological incubator.3.0 RESPONSIBILITY
Microbiologist - Quality Control4.0 ACCOUNTABILITY
Manager - Quality Control5.0 PROCEDURE
5.1 Ensure that material under test not to be disturbed during the calibration procedure.5.2 Calibration of the incubator is carried out by Five Pt 100 probes situated on four corners and one in center of the chamber inside the incubator.
5.3 For calibration of incubator scan the all four Pt 100 probes (channels) by pressing the SCANER key on the universal controller of incubator for 24 hrs.
5.4 After scanning take the print out of temperature mapping of 24 hrs duration by pressing the PRINT key on the universal controller of the incubator.
5.5 Record the minimum and maximum temperature attained during 24 hrs temperature mapping and record them in calibration record of the bacteriological incubator as per Annexure I.
5.6 Observe that all temperature values are within ±2.0º C tolerance limit to the set temperature value.
5.7 Frequency: Yearly once

My incubator is set on 44°C but during the calibration at some points the data logger recorded a temperature of 47°C . I Want to know is their any impact on the microorganism icubated in this case please i need an answer
ReplyDeletePractically it doesn't affect the microbial growth too much but theoretically it would be in specified limits.
DeleteAnkur sir, can you provide me reference for this temperature limits
