The room around the bench: cabinets, autoclaves and layout for a food microbiology lab in Thailand
The previous article listed the bench equipment the Notification 416 methods require. This one is about the room around it: which cabinet protects the worker and which only the sample, what the autoclave has to do and what the 2021 Ministry of Labour regulation calls it, the WHO core requirements for the room and the structure of ISO 7218:2024, and how far GMP 420 accepts results from a factory's own lab.

Equipping a food microbiology lab for MOPH No. 416: what the methods themselves require
MOPH Notification No. 416 names the analytical method for each pathogen, and every one of those methods carries its own equipment list.

What cleanroom class does an electronics or PCB plant actually need?
No Thai regulation prescribes a cleanroom class for electronics manufacture. The class comes from your process and your customer's audit. This article walks the real numbers in ISO 14644-1, the occupancy-state detail quotations love to omit, and how to split a TOR so the prices stay comparable.

Supplement factory QC labs: what Thai law actually requires you to test
Supplement criteria are not in MOPH No. 416; its Clause 4 excludes supplements outright. The real requirements sit in Clause 5 of MOPH No. 293 (B.E. 2548) plus the annual-testing duties GMP 420 attaches. This article walks the list and draws the line between in-house work and the accredited lab.

Pathogen testing under MOPH No. 416: the method table is your media list
Thailand's pathogen criteria for packaged foods come from MOPH Notification No. 416 (B.E. 2563), and its least-read annex names the exact analytical method for each organism. Work backwards from that table and the culture-media stocking list writes itself.
