Before your first inquiry.

Practical answers for laboratory and business buyers.

Who can send a product inquiry?

Laboratories, research organizations, ingredient businesses and procurement teams can send a defined requirement. Include your organization, intended application and destination so we can assess the request.

Are catalogue products available from stock?

Availability, exact identity, specifications, quantity and lead time are confirmed in a project quotation. A catalogue entry is a starting point for a supplier inquiry, not a stock reservation.

Can I request a COA before placing an order?

Yes. Tell us the product and any batch reference you have. We will request available supplier documents and identify what still needs confirmation. No batch reports are currently published on this website.

Can you source a product that is not listed?

Send the product name or sequence, required form, quantity, intended application and destination. We review supplier feasibility and the project scope before making a supply commitment.

How is pricing confirmed?

Pricing is quoted for each project. Product costs, samples, documentation or testing, packaging, sourcing services and freight are identified as applicable. No fixed service percentage applies to every project.
