SOP for Calibration BOD / Bacteriological Incubator

1.0 OBJECTIVE

To describe the procedure for the calibration procedure of BOD/bacteriological incubator.

2.0 SCOPE

This SOP is applicable for the calibration procedure of BOD/ bacteriological incubator.

3.0 RESPONSIBILITY

Microbiologist - Quality Control

4.0 ACCOUNTABILITY

Manager - Quality Control

5.0 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
