Before you order
Two things separate this shelf from the general reagent shelf. The first is storage: a large share of these substances are specified at +2 °C to +8 °C or below, and a consignment that has spent a week in a warehouse at 40 °C is not the substance you ordered — ask for the cold-chain arrangement before you place the order, not after. The second is grade: Molecular Biology grade carries nuclease and protease testing that Extra Pure does not, and no assay figure on a label tells you whether that testing was done.

What laboratories usually order alongside this.
Buffers & Culture Media
pH buffer solutions, capsules and tablets, biological buffer substances, and microbiological media components.
Organic Reagents
Organic acids, alcohols, aldehydes, amines, carbohydrates and synthesis reagents for preparative and analytical chemistry.
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.
