FAQs
Do you accept institutional purchase orders and tenders?
Yes. We provide formal quotations with grade, pack size, lead time and Incoterms that can be used for purchase orders and tender submissions.
Can I order small pack sizes?
Yes. Many reagents and biochemicals are available in gram and 100–500 mL pack sizes suitable for research and teaching labs.
Are some research chemicals controlled?
Certain reagents fall under narcotics-precursor, explosives or chemical-weapons conventions. We flag them at quotation stage, and the institution may need a permit or end-use certificate.
How do small research orders ship internationally?
Usually by express courier or air cargo with a COA and GHS SDS for each item. Flammable or oxidising items are packed within IATA dangerous-goods limits.
