Beschreibung
These turbidity standards remove the handling, stability and accuracy problems associated with traditional Formazin turbidity standards. They are certified traceable to NIST Reference Material 1690, and are available in a range of concentrations from 0–4000 NTU.
- Non-toxic and non-carcinogenic, with no special handling or disposal requirements
- Well defined spherical shape of particles, 0.01–0.2μm in diameter
- Particles stay in suspension—they do not deteriorate or settle out
- A long stable shelf life of 2 years at all concentrations
- Convenient, ready-to-use solution—mixing is discouraged as it entrains air
