Can you send me a free vial for testing?
We as distributors, as of our own, have no provision to supply free gift samples, unless the end user approaches our respective principals directly for the same and they give instruction to us to do the needful.
Can the standards be used in/on Humans?
Our products are intended strictly for research and laboratory purposes only and they cannot be used in and/or on humans in any way or form.
Do you accept Purchase Orders?
We accept purchase orders by email to email@example.com
We can't order unless Topclass has vendor registration.
Chances are that we are already a registered supplier to your institute/ organization. Please enquire from your purchase department, alternatively, you can call us. In case Topclass is not a registered supplier, please send us your vendor registration form and we will try to submit back the filled in form along with all the relevant documents at the earliest .
