PERITUBE Peridoser Replacement Tubing 500mm by Bluelab

The Peridoser Tubing is replacement tubing for the Bluelab Peridoser pumps. It is easy to replace. No other types of tubing should be used. The tubing requires replacement approximately every 18 months to 2 years to ensure reliable performance.

The Peridoser Tubing is sold as pre-cut 500mm lengths (1.64 feet), the required length for each individual peridoser pump. One length is required per peridoser pump. For example; a Triple Peridoser requires three lengths, a Twin Peridoser requires two lengths and a Single Peridoser requires one length.

WD-00652-48 Traceable® Conductivity and TDS Standard, Individually-Tested, 1000 μS; 500 mL by Oakton

• Oakton® Traceable® conductivity and TDS standards have detailed labels: KCl, NaCl, and 442 conversions, temperature corrections, and certified values referenced to 25°C-convenient!!
• Average accuracy at 25°C is ±0.25 microsiemens for 1, 5, 10 microsiemen (μS) solutions, or ±0.25% for all other solutions. The tested uncertainty is shown on the certificate, whichever is greater
• Conductivity options range from 1 to 200,000 μS/cm
• Individually-tested solutions are certified by the bottle - each bottle is analyzed for the best accuracy

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).

• All Oakton® Traceable® conductivity standards are NIST-traceable reference materials
• Supplied with a calibration report from an ISO 17034 and ISO 17025 accredited laboratory
• These standard solutions let you calibrate conductivity instruments to ensure accuracy
• If unopened, shelf life is one year; once opened, shelf life will vary by solution value
• Use when readings are expected to be around 1000 μS/cm

INCLUDES

temperature compensation chart, TDS conversion chart, and NIST-traceable calibration certificate with data.
