Lab chemical are precisely formulated chemical preparations used for analytical testing, calibration, and routine lab procedures. These include pH buffers, calibration solutions, volumetric solutions, and solvents, all of which are essential for ensuring the accuracy and reliability of laboratory testing and instrumentation.
At PMA and Online Reagents, we specialise in manufacturing high-quality laboratory chemical solutions that meet the needs of analytical laboratories, universities, research institutions, and quality control labs across the UK. Whether you require standard formulations or bespoke mixtures, our lab-grade chemicals are crafted with the precision and consistency needed for your critical applications.
The accuracy of any lab analysis hinges on the reliability of the chemicals used. Impurities or poorly formulated solutions can compromise test results, leading to inaccurate data, regulatory issues, or costly delays. Our laboratory chemical solutions are formulated to meet ISO9001 standards and undergo rigorous batch testing to ensure traceability, consistency, and compliance with UKAS-calibrated standards.
A laboratory chemical solution is a mixture of one or more chemicals in a solvent (usually water) prepared at precise concentrations for analytical or testing purposes.
All our chemical solutions are produced under ISO9001 quality control and feature full batch traceability and certification.
Yes, we offer bespoke chemical solutions tailored to your testing methods and instrumentation.
Yes, all our laboratory chemical solutions are produced to comply with REACH and COSHH guidelines.
With over 52 years of experience in precision chemistry, PMA is a recognised UK leader in the manufacture of high-purity laboratory chemical solutions. Our ISO9001-certified facility produces a wide range of analytical-grade products, including pH buffers, conductivity standards, titration reagents, and volumetric solutions – all formulated to exact concentrations and tolerances.
Each batch is subject to stringent quality assurance protocols featuring full traceability, Certificate of Analysis (CoA), and compliance with REACH and COSHH regulations. Our chemicals are used in critical applications across pharmaceutical R&D, forensic science, food safety labs, and environmental testing. From 1L lab packs to 30000L production drums, we support both standard and custom formulations tailored to your protocols and instruments.
World class customer service is what we're known for.
Looking for high-quality laboratory reagents, custom chemical blends, or white-label manufacturing? Our new platform, Online Reagents, is now live, your go-to destination for reliable UK-made chemicals, precision blending up to 30,000L, and ISO-certified quality.

It's one thing to say we make lab chemicals, but what does that mean for your day-to-day work? Whether you're calibrating instruments, running quality control checks, teaching chemistry, or preparing forensic samples, the solutions we manufacture are already complex at work in labs like yours every day. Here are some practical ways our laboratory chemical solutions are being used:
Our ISO-certified pH buffers are used to prepare and validate HPLC mobile phases for method validation in pharmaceutical quality control laboratories.
Our volumetric Sodium Hydroxide (0.1N–1.0N) solutions are used in automated titrators for water hardness and acidity testing.
Our AR-grade solvents (e.g. acetone, ethanol) are used to clean glassware, prepare sample dilutions, and extract analytes during crime scene investigations.
Our volumetric solutions and pH buffers are widely used in universities and colleges for chemistry experiments, titration practice, and pH standardisation.

Our forensic products are trusted by police forces, crime labs, and educational institutions across the UK, with every formulation manufactured to ISO9001 standards for consistency, traceability, and safety.
Our team of dedicated field support group technicians are vastly experienced in applications and installations. We therefore appreciate and understand how analysers work, why they were installed and what data they typically ought to produce.
