Placing Orders

U.S. domestic orders may be placed directly with our Customer Service team. International Orders may be placed through one of our International Distributors. Please check our International Distributor listing here.

Orders are binding only upon acceptance and acknowledgement by ZeptoMetrix Corporation. All orders are subject to ZeptoMetrix Terms and Conditions for product sales. Any clerical errors are subject to correction.

Standing Orders

Please inquire with Customer Service to establish a Standing Order. Standing Orders receive top priority in cases of stock shortages or back orders.

If an order does not have appropriate authorization for purchase or shipment, or is in some way inconsistent with regional, state, federal and/or international regulations, such an order may be delayed or terminated.


For non-damaged shipments, products may be returned only upon prior authorization from ZeptoMetrix Corporation. Perishable items containing expired material or opened vials cannot be returned. Returned product is subject to inspection by ZeptoMetrix Corporation prior to issuing credit. Shipping charges on all returns are at the customer’s expense. A 20% handling fee will be added to product returned due to customer order error.

Damaged Shipments

The delivering carrier, not ZeptoMetrix, is responsible for damage in shipment. Packing material should not be discarded when damage is observed. The delivering carrier should be contacted to inspect the damage. Damaged items cannot be returned without authorization.

Contact ZeptoMetrix Customer Service Department for instructions at (800) 274-5487 or email Customer Service at [email protected]


ZeptoMetrix will select the method of shipment and the carrier to be used unless otherwise specified by our customer. Temperature-sensitive products are shipped on dry ice or cold packs via air and are scheduled to arrive at the destination 24 to 48 hours after order receipt. Due to the sensitive nature of the products, deliveries will not be made over a weekend. All delivery dates are estimated.

Apply for Credit 

Invoicing under granted payment terms may be available upon completion of a ZeptoMetrix Credit Application and approval from our Finance Department.
