The goods are paid once. Split the week across three POs and you pay three freight lines.
On Monday the bench needs a chemical, a consumable that touches the sample, and an instrument or spare that reads the result. The method treats those three as one experiment. Purchasing often treats them as three vendors. Goods-in then books three deliveries for work that happened in one room.
The cost that repeats is not the bottle. It is the extra packing list, the extra receipt, and the SDS that arrives in a later email because the chemical was raised on a different order.
The freight rule, as written
The shipping policy is the source. Standard shipping is free from €250 net, excl. VAT. Below that, a transport surcharge of €9,89 may be applied. Cold chain, bulky or ADR lines can cost extra. Three orders that each sit under the threshold can mean three surcharges that may apply. One order that clears €250 pays standard freight at zero.
That arithmetic only works if the week’s lines can live on one list. Luminix Health puts 150.000 articles on one catalog: laboratory and industrial chemicals, consumables, labware and precision instruments. Microbiology when the week includes plates.
A practical test, not a discount: ROTI®Calipure 84 µS/cm is a conductivity standard and is not classified as dangerous goods. It can ride a mixed chemicals PO instead of opening a DG lane of its own. If the bench is being restocked in the same week, the EC820 conductivity meter is on the same catalog.
The file that travels with the order
The numbers that do not change with the SKU belong on the letterhead:
- EUDAMED SRN BE-IM-000049390
- FAMHP BE/CA01/1-75035
They are not a REACH file and they are not a CE certificate. Where a line is a chemical, the SDS belongs with that line, not in a chase mail after goods-in has already signed.
