A conductivity meter is only as good as the last solution you trusted. For low-range work, that solution is often 84 µS/cm at 25 °C.
Conductivity standard ROTI®Calipure, 84 µS/cm (25 °C) is on the Luminix Health catalog as SKU 2432.1 (500 ml, plastic) and 2432.2 (1 liter). The certified conductivity is 84 µS/cm ±1 % at 25 °C. It is certified according to ISO 17025. The value is traceable to an SRM from NIST.
That is the whole claim. Not “cutting-edge”. Not “save 30 %”. A number, a temperature, a standard, a traceability chain.
How it is used
You open the bottle, bring the standard to the temperature your method requires, and calibrate the meter before you measure samples. A benchtop meter on the same catalog, the EC820 precision conductivity meter, lists 84 µS/cm among the supplied standard solutions. The Calipure bottle is the refill and the audit trail when the 50 ml vial that came with the instrument is gone.
Keep the glassware clean. Rinse the cell with the standard, not with a leftover sample. Read at the temperature you record. The specification prints an informative temperature table from 5 °C to 50 °C; those extra points are marked as not measured in each batch. The certified point remains 84 µS/cm at 25 °C. Recommended storage on the safety data sheet is 15–25 °C.
What the user can check
The user can check these facts on the product page:
- Density: 1 g/cm³. Boiling point: >60 °C (catalog description).
- Identified use: laboratory chemical / laboratory and analytical use. Not for private household use.
- CLP: the mixture does not meet the criteria for classification. Labelling is not required.
- Transport: UN number not assigned; not subject to transport regulations (ADR/RID/ADN, IMDG, IATA). In buyer language: not dangerous goods. That matters on a mixed PO, because this bottle does not force a DG lane.
GHS/SDS sits with the article, not in a follow-up email if you have to chase it. The technical documentation PDF is on the product page.
Why order it on this catalog
The bottle is one line in Laboratory & Industrial Chemicals, next to the precision instruments that read it and the labware you rinse it with. Consumables (tips, tubes, rinse bottles) go on the same PO.
Luminix Health lists 150.000 articles. EUDAMED SRN BE-IM-000049390. FAMHP BE/CA01/1-75035. Standard shipping is free from €250 net, excl. VAT; below that a transport surcharge of €9,89 may apply. ADR, cold chain or bulky lines can cost extra (shipping policy). Dispatched from the heart of Europe.
A conductivity standard that is not DG is exactly the line you add when you are already consolidating a chemicals order and do not want a second carrier class.
