Return Policy

Please contact Analytical West toll free at 1-888-948-WEST (9378) to obtain a Return Authorization (RA) Number. Reference this number on all correspondence related to your return. Your AW Customer Service Representative will advise you of the proper shipping instructions. Returns must be made within 30 days of issuance of RA Number.

Products not supplied as ordered and products defective at the time of receipt are acceptable for full credit. Products ordered in error are subject to restocking charges.

If a problem occurs with a product that has been used in any way, under normal wear & usage, the item will be handled as a warranty issue, not as defective. Return shipping charges for warranty items are the customer's responsibility.

All products carry a full manufacturer’s warranty. Should a problem arise within the manufacturer’s warranty period, Analytical West will do everything possible to assist in resolving your concern. It is at the manufacturer's discretion to repair, replace or refund item. If needed, please call to inquire about a particular manufacturer's warranty time period.


Analytical West is committed to being the preferred vendor for all of your instrument supplies. As such, we want you to understand our prices, and the prices that the manufacturers suggest we post for informational purposes. All web prices reflect suggested list prices as provided to Analytical West by our suppliers (such as Detector Technology or Precision Glassblowing).

As our manufacturers update their price information, we do our best to update the prices posted on our website. At times, however, the list price of an item might change without being immediately reflected on the website. For such reasons, please contact us toll-free at 1-888-948-WEST (9378) for the current price of a particular product.

You will be contacted in the event that your online order reflects incorrect or outdated pricing. The Purchaser has the option to cancel the order, or to proceed at the corrected price. Please contact us at if you have any questions or comments about our pricing or other policies.
