pH Buffers
pH buffers are calibration and reference solutions (and dry buffer powders/capsules) of defined pH — commonly pH 1.68, 4.01, 7.00, 9.18 and 10.01 at 25 C — used to calibrate pH meters and electrodes across laboratory, water-treatment, food, pharmaceutical and educational settings. Buyers select them by nominal pH, traceability, stated uncertainty and temperature-compensation data, because calibration accuracy depends on certified values and a documented temperature chart rather than the bulk chemistry alone.
Grades span technical calibration solutions and certified reference materials (CRM) traceable to NIST and/or PTB primary standards. Certified buffers are typically certified within close tolerance of nominal value, often around 0.01 to 0.05 pH unit, with a serial-numbered certificate, lot number, an associated uncertainty and a temperature-compensation table; producers commonly work under ISO/IEC 17025 and ISO 17034 accreditation. Colour-coded solutions and DIN/NIST-aligned value sets are available. CAS and HS framing is provided on documentation rather than assumed here.
Forms include 250 mL, 500 mL and 1 L bottles, single-use sachets and capsule/powder buffers for field reconstitution; bottles carry lot, value, expiry and traceability labelling.
For EU import, REACH applicability for the buffer salts and CLP/GHS labelling are coordinated where required, with SDS supplied (most buffers are low-hazard, though acidic/alkaline extremes are classified accordingly). SABER/SASO is coordinated for Saudi Arabia.
Himalay's verified manufacturer and exporter partners supply pH buffers with a serial-numbered certificate and CoA per batch, SDS, REACH/CLP compliance coordinated for EU, GHS labelling, and SABER for Saudi Arabia handled as part of the standard order flow.
