pH Buffer

All Weiss color coded pH buffers are designed for ready-to-use, immediate identification, ease of reseal and mold controlled for long term pH calibration. All pH buffers are made from high-purity deionized water and ACS reagent chemicals, and weigh chemicals to 4th decimal point. Each lot of these buffers is checked against the buffer solutions which traceable to the NIST.

WiseCal™ pH Buffer

WiseCal pH Buffer

Use WiseCal™ pH Buffer solutions, you can benefit from:

  • Easy-to-carry, No more containers to carry, great for field use. Unlike the pouch buffers are too difficult to handle - you have to tie up one hand and use the other hand to hold the buffer or constantly search for something to support the pouch to stands up. WiseCal allows you free both of your hands and finish your job easily and effectively.

  • Easy-to-use and allow to calibrated pH electrodes (also conductivity & ORP) directly in the bottle. No other containers are required!

  • No more container to clean.

  • Long-life stability specially for basic pH buffers. No more worry about risk of contamination.

  • Accurate, NIST traceable

  • Very Economical, No more wasted solutions from overfilling. Just Switch to WiseCal™ pH Buffer from pouch buffer, you can save more than $876* per year.

* Assume the calibration twice a day and use two buffers. Pouch buffers cost about $1.00/each or more. One bottle WiseCal™ pH Buffer contains 500-ml solution and can be calibrated more than 25 times.

How to use WiseCal™ Buffers?

  1. Simply loosen the cap, black, from measuring chamber. Don’t loosen and remove the cap from the filling mouth of the bottle, white one, to prevent the solution exploring to the air and get contaminated.

  2. Gently squeeze the bottle to fill measuring chamber with required amount of  solution.

  3. Remove cap, black one, from measuring chamber.

  4. Insert the electrode into measuring chamber to do the calibration.

  5. After calibration, pour out of the solution in the measuring chamber.

  6. Re-cap the measuring chamber with that black cap.
