Calibration Buffers & Standards
Hamilton offers a complete range of patented pH / ORP buffer solutions and conductivity standards. These products are specifically designed for Hamilton sensors and feature high stability and industry leading shelf life.
DuraCal ORP Buffers
Hamilton ORP buffers are stable for two years. You can always rely on them even if they have been used.
DuraCal pH Buffers
Patented buffer solutions provide pH stability of up to five years. High buffering capacity provides rapid and stable calibration.
Stability from 1 to 3 years respectively and conductivity ranges from 1.3 µS/cm to 100 mS/cm

How does the DuraCal buffer bottle work?The Calpak bottle is a unique, patented design which includes a small chamber at the top of the bottle that fills with buffer solution when the bottle is squeezed. Click to see a simple pictorial of how to use this bottle.
Documentation and Certificates for Sensors and Liquid SolutionsWhat documentation and certificates can I expect with my electrode or buffer? This article provides examples of the types of paper documents that normally come with Hamilton products.
Tips to Improve pH MeasurementAccurate pH measurement and control is fundamental for a wide variety of laboaratory processes. Some of those processes are based on cell or microbial cultures where the pH value has to be kept within a narrow range. This video shows the three most helpful tips to ensure optimal growth and product yield.
Work with R&D engineers to customize Hamilton parts
Hamilton's "Custom Built" program puts you directly in contact with a Hamilton R&D Engineer to discuss your application and product needs. The engineer will point you to a standard solution or propose a customized solution to meet your needs.Talk to an engineer
