Before you order

A volumetric solution is only as good as its factor. Ready-to-use solutions arrive standardised with the factor printed and dated, which removes an entire standardisation step — and an entire source of error — from your titration. Concentrate ampoules suit laboratories that consume slowly and want a longer shelf life; one ampoule makes one litre.

What laboratories usually order alongside this.

Acids & Bases

Mineral and organic acids, alkalis and hydroxides across Extra Pure, AR, pharmacopoeial and trace-metal grades.

Indicators & Stains

pH, redox, complexometric and adsorption indicators, and biological stains with certified dye content.

Standards & Reference Materials

AAS and ICP single-element standards, ion chromatography standards, conductivity and colour standards, and NIST-traceable reference materials.

Three things worth checking before you raise the purchase order.

Grade is not a luxury decision. An Extra Pure solvent in an HPLC mobile phase produces a rising gradient baseline and ghost peaks that cost more in re-runs than the grade upgrade would have cost. Equally, buying analytical grade for a teaching practical wastes real money across an academic year. Match the grade to what the result has to survive.

Hydration state changes what you weigh. Magnesium sulphate heptahydrate has a molecular weight of 246.48; the anhydrous salt is 120.37. They carry different CAS numbers and are different products. Catalogues frequently print only “magnesium sulphate”. Every listing here states the hydrate.

Concentrated acids are quoted as cartons, not bottles. 2 × 500 ml and 4 × 2.5 L are the standard configurations in this trade. Comparing a per-bottle price against a per-carton price is the single most common quotation error we see, and it is usually the buyer who absorbs it.

Bulk quantities — 25 kg, 50 kg, 200 L drums — are priced on request because freight and packing dominate the cost. Send us your annual consumption and we will quote a schedule rather than a line item.
