Frequently asked questions
What is the difference between AR and LR grade?
AR (analytical reagent) meets published assay and impurity limits for quantitative analysis; LR (laboratory reagent) is a general-purpose grade for preparative and teaching use.
Do you supply certificates of analysis?
Yes, for AR, ACS, HPLC and IP/BP/USP grades, with batch number and date.
What are the minimum pack sizes?
Typically 100 g / 100 ml or 500 g / 500 ml for reagents, 2.5 L for solvents; bulk packs for repeat users.
Can colleges and research institutes order on credit?
Institutional orders on purchase order are accepted.
Do you ship hazardous lab chemicals by courier?
Non-restricted items by courier; acids, flammables and oxidisers by road transport with the correct documentation.
