## Overview

This 3-pack pH buffer calibration kit includes pH 4.00, 7.00, and 10.00 solutions in 250 ml color-coded bottles, each NIST-traceable and lot-numbered for guaranteed accuracy and freshness. Designed for all pH meters, it’s the trusted choice for pharmaceutical, academic, research, and industrial labs seeking reliable, easy-to-use calibration standards.

## Description

These buffer calibration solutions are suitable for the calibration of all pH meters. Each production lot is manufactured in our own laboratory following carefully controlled written procedures and standardized against NIST standard reference materials (SRM) for high accuracy. The finished product is assigned a unique Lot number and expiration date. These products will have greater than one year shelf life when received. Certificate of analysis and traceability included.

Review: My New Go-To pH Buffers - Great value and a nice size that won't expire before I use it all. Solutions were accurate and came with certificates. pH 10 buffer read 0.02 higher than indicated on paperwork, but the 10 buffer is the hardest to keep stable and needs to stay fresh, so that's not bad. Other pH 10 buffers I have received have been off by as much as 0.45. These will be my go-to pH buffers if the price remains this reasonable.
Review: Good stuff! - They came in and are doing great, we are glad that the expiration dates are far out, We don't use a lot of this, so our standards usually expire before the bottles are empty.

## Questions & Answers

**Q: Please advise the expiration date for biopharm buffer calibration solution kit 3-pack of 250 ml (8oz) each ph 4, 7 and 10 calibration standards color**
A: The buffer pH 4 and 7 have a shelf life of 2 years when unopened. The buffer pH 10 has a shelf life of 18 months when unopened. These expiration dates are assigned before they head to the amazon warehouse so you will have slightly less than that.

**Q: What would be the shelf life after the biopham calibration solution is opened?**
A: I think each bottle lists it’s expiration date on it, which we treat as it’s expiration date whether it is opened or not.  How long that is depends on how long it was between manufacture and shipping. I think most of the time this probably has about a year shelf life once you get it, but that would be variable.
