Conductivity standard at 25°C is tested by an ISO 17025 Accredited (A2LA Ref: 6739.03) Test Method and NIST traceable. The product is aqueous based; non-hazardous and accurate to a specification of ±1%. The product because it is aqueous based; has a low temperature coefficient of variation and guaranteed stability throughout its entire shelf life; even after opening the bottle.

NIST traceable

Aqueous based, thereby eliminating any errors attributable to matrix mismatch

Each bottle is supplied with a comprehensive Certificate of Analysis and has a table of conductivity variation with temperature printed on the product label

Low temperature coefficient of variation, reduces measurement errors and enables non-temperature controlled use and is suitable for field work

High accuracy ±1% at 25°C, enables the standards to be used as calibrators and/or controls, in accordance with the most exacting industrial requirements

Guaranteed stability throughout entire shelf life, even after opening the bottle, eliminates the need to open a fresh bottle of standard every time it is used

Certified RNase and DNase free

Sterile

Manufactured from virgin ultra clear polypropylene

Leak proof flat HDPE cap

Printed graduations and a large writing area for sample identifications

Racked tubes are packaged in recyclable card racks

Lot traceability

RCF: 15000xg (15mL) or 12000xg (50mL)
