## Overview

The Biopharm pH Buffer Calibration Solution Kit includes three 250 ml bottles of pH 4.00, 7.00, and 10.00 buffers, each color-coded and NIST-traceable for unmatched accuracy. Designed for professional labs, this kit ensures reliable pH meter calibration with batch-specific lot numbers and expiration dates, backed by certificates of analysis. Ideal for pharmaceutical, academic, research, and industrial applications, it offers a perfect balance of volume and precision to keep your measurements flawless.

## Description

These buffer calibration solutions are suitable for the calibration of all pH gauges. Each production batch is manufactured in our own laboratory following carefully controlled and standardized written procedures according to NIST standard reference materials (SRM) for high accuracy. The final product is assigned a unique lot number and expiration date. These products will have a shelf life of more than one year when received. Certificate of Analysis and Traceability Included.

Review: 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.

## 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.

*by M***K on 9 March 2017*

I am a chemist working in my own small lab. I like the size of standard solutions, very well packed with certificate of analysis for each standard. I do not use much of the standard so I am expected to have them until expired. However, I hope this product is available in case I need to buy them again. I highly recommend this product for calibration or standardization of pH meter.
