Supplier: Thermo Fisher Scientific

CAS No.: 1332-57-6

Supplier: WTW

Adapted to different electrode types for calibration and maintenance.

Supplier: CPACHEM

Shelf Life on Ship Date: 12 months - Store under normal laboratory conditions, at temperatures between 15 to 25 °C.

Supplier: SI ANALYTICS

Buffer solutions intended for extremely precise calibration.

Supplier: Greisinger

Cost-effective alternative: Buffer capsules and working sets. With buffer capsules, you can produce a 100 ml buffer solution in the most cost-effective manner. A particular advantage of the capsules is that their storage life is several years longer than that of ready-to-use solutions.

Supplier: WTW

Every bottle has its own lot reference with the expiration date.

Supplier: WTW

These standard buffer solutions (work reference buffer solutions) are widely used in precision applications.

Supplier: REAGECON

This range of Reagecon pH Buffers are sodium tetraborate (Borax) free. They are not subject to classification by EU regulatory authorities as toxic to reproduction under CLP category 1B. Similar in approach to the existing range of Reagecon Mercury Free Buffers, these Buffer Solutions have been developed to enhance user choice and allay safety concerns, without any impact on fitness for purpose or product performance.

Ammonia - Ammonium chloride buffer solution.

Supplier: Hanna

These technical calibration buffers produced in accordance with ISO 3696/BS3978 standards using high purity salts, deionised water, certified weight-checked balances, and Class A glassware in a temperature controlled environment monitored with certified thermometers.

Supplier: Hanna

Solutions in sachets ensure optimum precision. The plastic-coated sachet provides a perfect liquid seal and good protection from light. The solutions should only be used once to avoid any danger of contamination. They also satisfy the requirements of the GLP and ISO standards. They have been adjusted using a pH meter that has been calibrated according to the NIST standards.

Supplier: Thermo Fisher Scientific

Delivers robust reproducible gradients with the Thermo Scientific™ pH buffer platform that is applicable to a wide range of MAbs and ready to use with existing LC columns and systems, without the need to formulate mobile phases.

Supplier: Thermo Orion

Perform accurate, reproducible pH calibrations with Orion™ pH buffers.

Supplier: Mettler - Toledo

Solutions in sachets ensure optimum precision.

Supplier: Thermo Orion

Buffers for calibration giving fast, accurate pH results in high purity and low ionic strength waters. Recommended for samples such as well water, rain water, distilled/deionized water, boiler feed water, and process water.
