All sales are subject to our Terms and Conditions.

Sales Tax

We currently collect sales tax in the following states:

California (variable; 7.25% – 10.75%)
Massachusetts (6.25%)
North Carolina (variable; 6.75% – 7.5%)

All orders shipped into those states will have sales tax applied to the price of the product (excluding shipping) during checkout. For California and North Carolina, we initially apply the highest rate; this is corrected later. Here is how it works: When you submit your order, your credit card is not charged right away, but the purchase amount is authorized for later capture. This gives us time (in case of CA and NC) to look up the actual tax rate that applies to the shipping address and adjust the tax on your order accordingly before we capture the amount.
Likewise, if you indicate that your purchase is tax exempt, the temporary hold on your card allows us to verify that we have your tax exempt certificate on file, or request one from you before we ship.

Please notify us of your tax exempt status before you order; you can also use the Comments field on the order form. You can further accelerate the process by submitting your tax exempt certificate to (preferred) or faxing it to (978) 865 9499 before you buy. In Massachusetts, this can be Form ST-4 (Resale Certificate), ST-5 (Sales Tax Exempt Purchaser Certificate), or ST-12 (Exempt Use Certificate), as the case may be.

Domestic Shipping

Orders are shipped via FedEx and actual shipping charges for the selected service (Express Saver, 2Day etc.) added to the order total during checkout. Ground shipping is free on all credit card orders to the lower 48 states. If you need your order faster, please select the desired shipping method during checkout.

International Shipping

We are happy to ship direct to our foreign customers and strongly encourage you to order online. If you do not wish to purchase online, we still ask you to kindly pay in advance. If a proforma invoice is required for pre-payment, fax or email your order form and we will be happy to send one. You can send a check in US dollars, drawn on a US bank, or you can wire the money directly to our bank. Our bank details will be shown on the invoice.

Important: Our Incoterms are DAP (or EXW if you ask us to ship on your FedEx account). This means that the buyer is responsible for import fees, such as duties and taxes. Those fees will be collected by FedEx before or at the time of delivery.

To avoid any delayed shipments, be sure to mention the full name and address of the recipient, including phone number and email, when you order. If anything is unclear about the delivery or customs clearance, FedEx will try to contact the recipient using this information.

We would like to have an open return policy, but this is not practical given the nature of the work done by our customers. If the product has been used with hazardous materials (radioactive, biological, chemical) we cannot take it back. If the product has been used with a material that renders it useless or unsellable (such as a dye or material that leaves a visible residue), we cannot take it back. Unfortunately, in most cases this is what will happen to products once they have been used in a research setting.

As long as the product is used as it was designed to be used, then we will make every attempt to make sure that it is functioning for that purpose.

Our products are under warranty for defects in material and workmanship for one year after purchase.
