What different labs need

Grade matters more in the lab than anywhere else. The same chemical can be sold as technical, laboratory reagent (LR), analytical reagent (AR) or HPLC grade, and the grade sets the impurity limits your method can tolerate.

  1. Water testing

    Plant and environmental labs test hardness, chloride, alkalinity, chlorine and pH every day.

    Chemical typesEDTA titrant with Eriochrome Black T indicator for hardness; silver nitrate with potassium chromate for chloride; phenolphthalein and other indicators for alkalinity; buffers and pH papers; test kits.

  2. Oilfield and drilling labs

    Mud engineers and production labs test mud properties, filtrate chemistry and produced water.

    Chemical typesMethylene blue for the methylene blue test (MBT) of clay content; silver nitrate for chloride; solvents such as xylene; salts for brine work.

  3. QC and instrument labs

    Chromatography and other instruments need high-purity solvents and water to give clean baselines.

    Chemical typesHPLC-grade methanol and other solvents, AR-grade acids, DI and HPLC-grade water, buffer solutions for pH meter calibration.

  4. Teaching labs

    Schools and colleges need common reagents in small packs and basic apparatus.

    Chemical typesCommon acids, bases, salts and indicators; beakers, measuring cylinders, pipettes, burettes and filter paper.

  5. Microscopy and staining

    Clinical and biology labs stain samples to see structures.

    Chemical typesStains and indicator dyes such as methylene blue.

Lab chemicals: questions buyers ask

What is the difference between LR, AR and HPLC grade?

LR (laboratory reagent) grade is for general lab work and teaching. AR (analytical reagent) grade has tighter, stated impurity limits for quantitative analysis. HPLC grade solvents are also filtered and tested for low UV absorbance and residue so they suit chromatography.

Which reagents are needed to test water hardness?

An EDTA titrant, a pH 10 ammonia buffer and Eriochrome Black T indicator. The colour changes from wine red to blue at the end point.

Which buffers are used to calibrate a pH meter?

Usually pH 4.00, 7.00 and 10.00. Calibrate with two or three buffers that bracket the pH of your samples.

Do you supply distilled and deionised water for labs?

Yes: lab-grade distilled water, DI water and HPLC-grade water.

Do you supply lab glassware?

Yes, basic apparatus such as beakers, conical flasks, measuring cylinders, pipettes, burettes and filter paper.
