  1. Please indicate the product model number if you have specific questions about the product that you could not find on this website.

  2. If you want to know about the product prices and the shipping cost only to estimate your budget, please say so.  We'll email the information to you, but no products will be reserved at this stage.

  3. If you are sure about the purchase, please provide your full address (PO box not accepted), recipient's phone number, and email address.  We'll then prepare an official quote and keep the products for you.  We assume we'll be paid upfront (preferred) after you receive our quote.  Please clarify if your institution has a "pay by invoice" policy.  In such cases, we encourage that you purchase from our distributors near you.  If that is not possible, we'll wait for your official purchase order before we can ship the order.

  4. Some of our popular products sell out very quickly.  If you require particular items urgently, we suggest placing the order online as soon as possible.

  5. All quotes are effective for 14 days.  Our carrier adjusts shipping rates weekly due to the Russian-Ukrainian war.  We reserve the right to amend the shipping cost if our transaction cannot complete in 14 days.
