Dry Heat Oven Process Validation/Qualification

Dry Heat Oven Process Validation/Qualification

Dry heat ovens are used in pharmaceutical manufacturing for the sterilization and depyrogenation of glassware, instruments, and materials that cannot withstand the moisture conditions of steam sterilization. Validating a dry heat oven requires precise temperature mapping and the use of appropriate biological or endotoxin challenge systems.

IETQAN validates dry heat ovens in accordance with EU GMP Annex 1 and PDA Technical Report No. 3. Our validation scope covers heat distribution studies, heat penetration studies for defined loads, and — where depyrogenation is claimed — endotoxin challenge testing to demonstrate the required 3-log reduction. All validation reports are prepared in GMP-compliant format. We deliver these studies using the Ellab A/S validation system that fulfils FDA 21 CFR Part 11, ISPE GAMP 5 and EU Annex 11 Volume 4 requirements, enabling quick service delivery through automated calibration and verification and on-site report generation — reducing equipment downtime.
