WPI values its customers and will make every effort to maintain the highest professional and ethical standards. However, WPI regards as invalid any special terms and conditions set forth by any other party, including purchasing, quotations, warranties or other statements. WPIs response to a quotation, purchase order or inquiry shall not be construed as acceptance of any conditions stated therein.

Credit Terms

Standard Equipment & Accessories

To insure against misunderstandings or delays, always include model number, name, and significant specifications of systems and accessories when ordering. Also specify any options desired. WPI retains the right to change specifications or discontinue products without prior notice and without responsibility for incorporating such changes into equipment previously sold. Please state the desired operating line voltage and frequency.


WPI strives to maintain the highest quality standards in all products. We warranty these products against defects in workmanship or materials, and all WPI products retain a warranty that is stated in the products manual. (Typically, one year for parts and labor except for consumable items such as electrodes, glass, etc., for which warranty varies from 30 days to six months.) However, WPI hereby specifies that no use or application of any product may be suitable or successful for a specific application and therefore waives all liability in that regard. It is the sole responsibility of the buyer/user to apply the product in a manner consistent with its intended use. WPI products are not approved for human use unless specifically stated in writing with accompanying FDA (or applicable) documents. WPI assumes no liability or legal, moral, ethical, or fiduciary responsibility for a use of any product in the WPI catalog in treating or studying humans.


WPI maintains competitive world wide pricing. Prices listed for standard items as described are net and subject to change without notice. Prices (in U.S. dollars) do not include shipping charges. Formal quotations are valid for a period of 30 days unless otherwise specified. Purchases may be charged to your VISA, MasterCard, or American Express account.


We reserve the right to add any taxes required by local law or ordinance. Institutions operating under tax-free conditions must state applicable license or contract number and be prepared to furnish necessary exemption certificate.

Packaging and Shipping

Equipment is shipped in adequate commercial packing. All packages should be checked thoroughly before being discarded. Packages are shipped Ex-Works and shipping and handling fees, including adequate insurance coverage, are paid by the customer.

Claims and Returns

Inspect all shipments upon receipt. Missing cartons or obvious damage to cartons should be noted on the delivery receipt before signing. Concealed loss or damage should be reported at once to the carrier and an inspection requested. All claims for shortage or damage must be made within ten (10) days after receipt of shipment. Claims for lost shipments must be made within thirty (30) days of receipt of invoice or other notification of shipment. Please save damaged or pilfered cartons until claim is settled. In some instances, photographic documentation may be required. Some items are time-sensitive; WPI assumes no extended warranty or any liability for use beyond the date specified on the container. Do not return any goods to us without obtaining prior approval and instructions from our Returns Department. Goods returned unauthorized or by collect freight may be refused. Goods accepted for restocking must be in new condition, returned within 30 days, and will be exchanged or credited to your WPI account and are subject to a restock fee of 25%. No cash refunds will be given. Goods returned which were ordered by customers in error are subject to a 25% restock fee. Equipment which was built as a special order cannot be returned.


Contact our Returns Department for assistance in the repair of apparatus. Do not return goods until instructions have been received. Returned items must be securely packed to prevent further damage in transit. The Customer is responsible for paying shipping expenses, including adequate insurance on all items returned for repairs. Identification of the item(s) by model number, name, serial number and proof of purchase (packing slip number or invoice number) as well as complete description of the difficulties experienced should be written on the RMA request form and a copy of the form must be included with the item.
