- 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. How many incubator temperatures, which petri dish sizes, how tight the water bath: the texts say. This article walks the workflow in order and collects the list on one page.
- Only a photo or an old model number? How to request the right equipment
A faded label, an old quotation or a photo can start a sourcing request. Here is what to photograph, which codes to copy and what to tell your supplier before accepting a replacement or an alternative.
- When is buying several equipment brands through one supplier worth it?
A mixed equipment list can mean several quotations, delivery dates and contacts. Learn when one supplier can reduce that work, when separate purchases make sense, and what to compare before you order in Thailand.
- Setting up an electronics plant in Thailand: what to buy locally
Nearly 60 PCB and electronics makers are commissioning Thai plants, and every one of them hires a local procurement desk. This guide is for that desk and the HQ team behind it: what ships with the line, what should be bought in Thailand, the Thai paperwork your head office will ask for, and why the QC lab and the cleanroom belong on the same schedule as the process line.
- What a PCB factory's QC lab actually needs
Close to 60 PCB makers are commissioning plants in Thailand, and every one of them answers the same auditor questions: how do you control your baths, how do you check incoming material, and where are the records? This article walks the lab bench by bench, with a straight opinion on what to buy first and what to outsource.
- 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.
- Thai hospital labs after the ISO 15189:2022 deadline: two accreditation tracks, one equipment paper trail
The transition to ISO 15189:2022 closed on 6 December 2025, so every accredited medical lab is now assessed against the new edition. This article compares Thailand's two tracks, the Medical Technology Council's LA and ISO 15189 through the Department of Medical Sciences, and lists the documents procurement must obtain with every instrument.
- 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.
- Routine water testing for Thai factories: what changed in 2025
Notification No. 462 B.E. 2568 replaced the drinking-water standard most Thai suppliers still quote. The current limits, which water tests belong on your own bench versus an accredited lab, and two things GMP 420 does not require.
- Buying lab supplies from Thailand: Cambodia, Laos and Myanmar
The ASEAN duty preference applies to Thai-made gloves and reagents, not to the European instruments a Thai distributor merely holds in stock — plus the border routes, the payment reality in each country, and what cannot cross at all.
- Setting up a factory QC lab in Thailand: an equipment checklist
Which tests belong on your own bench and which belong at a contract lab, what GMP 420 actually requires (it does not require you to own a laboratory), a checklist by lab function, and why an internal QC lab almost certainly does not need ISO/IEC 17025.
- Sourcing lab equipment and supplies from Thailand: a buyer’s guide
What is genuinely worth buying from Thailand’s lab market and what is not — territorial brand agreements, dangerous-goods chemistry, freight economics — plus how an export order runs from quotation to customs documents.
- Writing a lab-equipment TOR that more than one supplier can bid on
Section 9 of the Procurement Act forbids a specification written close to one brand. Here is how to tell a requirement from a catalogue line, how to write ranges instead of single values, and what a supplier should do when a TOR is locked.
- Registering as a government supplier in e-GP: the procedure, the deadline and the documents
Government agencies cannot buy from an unregistered supplier. Here is the e-GP registration procedure, who approves it, the 15-day deadline that cancels an application, and when to start so you are ready before the tenders appear.
