WD-98767-77 Traceable One-Shot Buffer Solution, Red, pH 4.005; 6 x 100 mL Vials by Oakton

• Convenient, single-use vials eliminate concerns of cross-contamination; each pack contains six polyethylene vials with 100-mL of pH buffer per vial
• If unopened, shelf life is 2 years; once opened, use pH 4 and pH 7 within 90 days, pH 10 within 30 days

Oakton® Traceable® One-Shot™ pH Buffer Solutions are supplied with NIST-traceable calibration reports stating accuracy at 25°C to ±0.010 pH, in addition to conversion values for pH/temperature - for the most accurate calibrations!

METHODS SUPPORTED

Certified reference material meets test requirements for Federal, State, and local agencies, CAP, ASTM, NCCLS, CLSI, ACS, CLIA, AOAC, EPA, APHA, AWWA, WEF, USGS, USP, and ISO. Traceable® Conductivity Standards complies with and is essential for use in these official methods: AOAC 973.40, EPA 120.1, Standard Method 2510 (APHA, AWWA, WEF), ISO 7888, DIN 38404, ASTM D1125, USGS I-1780, USP 645, and for A2LA/NVLAP accreditations/ISO 9000 certifications. Material may be used to calibrate all conductivity meters and to determine all conductivity cell constants.

A2LA ACCREDITATION ISO/IEC 17025:2005 (1750.01)

To assure accuracy an individually serial-numbered Traceable® Certificate is supplied to indicate traceability to standards provided by NIST (National Institute of Standards and Technology) and/or a National Standards Laboratory. A2LA accredited certification provides the highest achievable level of quality assurance, documentation, and accuracy. Conductivity Standards are produced in an A2LA accredited ISO/IEC 17025:2005 (1750.01) calibration laboratory. Additional certifications include ISO 31 (certificate content) and ISO 35 (statistical analysis), plus ISO 9001 (certified quality manufacturer).
