Selected enzyme preparations
Examples from the S&T catalogue include catalase liquid (12 months) and lactase powder (24 months). Shelf life is product-specific and depends on the stated storage conditions.
Follow the product sheet and batch expiry. Concentrate shelf life does not establish the stability of a prepared dilution or every component in a kit. Ask us for remaining shelf life before ordering.

Enzyme experiment kits: your questions.
Which enzymes can be used in school experiments?
Common starting points include amylase for starch digestion, catalase for oxygen production, protease for protein breakdown, lipase for fat hydrolysis and pectinase for fruit processing. Lactase and other preparations can support extended investigations. Suitability depends on the preparation, protocol and teaching context.
What is in the 3-enzyme kit?
ProStar Enzyme Kit I contains amylase, cellulase and glucoamylase. It is an enzyme collection; supporting reagents, substrates and equipment should be planned separately.
What is in the 7-enzyme kit?
ProStar Enzyme Kit II contains amylase, cellulase, glucoamylase, lipase, pectinase, protease and xylanase. Check the current product listing for the final pack contents and sizes.
How do I calculate the cost of an enzyme experiment?
Divide the pack price by the pack quantity and multiply by the concentrate used per test. Add other consumables, then multiply by your working groups, tests and repeats. The calculator also shows class costs, costs per student and the whole packs needed.
