A measurement is only as good as its calibration. Thermal Scientific stocks pH buffers, conductivity standards, ORP standards, turbidity standards, ion selective electrode standards, and metal standards for ICP-MS and AAS, so your team can calibrate and verify instruments against trusted references. Field crews checking source water, flowback, or discharge samples and QC labs running routine compliance testing both depend on fresh standards, and our selection includes manufacturers such as Aqua Solutions, Ricca Chemical, LabChem, and Hach.
Start with the standard that matches your instrument: pH buffers, conductivity standards, ORP calibration standards, turbidity standards, or metal standard solutions for ICP-MS and AAS. Looking for Hach-brand standards? Browse our Hach supplier page, and ask about Vendor Managed Inventory to keep your most-used standards on hand.
Match the standard to the measurement: pH buffers for pH meters, conductivity standards for conductivity meters, ORP standards for redox probes, and turbidity standards for turbidimeters. Your instrument manual lists the values it calls for, and our team can help you find them.
Follow the shelf life and storage guidance on the label and your testing method. Opened solutions can degrade or pick up contamination, so many labs use fresh solution for each calibration.
Yes. Our Vendor Managed Inventory (VMI) program keeps recurring consumables like buffers and standards stocked automatically, so calibration never waits on a reorder.
