Pre-packed columns, bulk resins and consumables

TSK-GEL column products are accompanied by a chromatogram demonstrating the performance of a test mixture on the column and by an OCS sheet that contains information about the Operating Conditions and Specifications of the column. TSK-GEL and Toyopearl bulk media products are accompanied by a Certificate of Analysis.

Despite our commitment to product quality, columns and resins occasionally perform differently than expected in a customer's application. Therefore, we ask you to inspect your TSK-GEL or Toyopearl product within 30 days of receipt by using the conditions described in the documentation supplied with the product. Within this 30-day period, please contact Technical Service to obtain a Return Material Authorization (RMA) if the product does not meet the specifications on the OCS sheet and QC document, or as listed in the Certificate of Analysis.

Hardware accessories should be inspected for damage upon delivery. If defective, please contact Technical Service to obtain a Return Material Authorization (RMA). Tosoh will exchange the defective part at our expense, for a part which meets specifications.

Subject to prior written authorization, we will accept for return all columns, resins, and consumables that do not perform according to their specifications. If a product is authorized for return for reasons other than an error that can be attributed to Tosoh Bioscience or because of a product defect, there will be a restocking charge of 25 EUR or 10% of the list price, whichever is greater.

Tosoh Bioscience will not accept any product returns without an RMA issued by the company. Call +49 (0)711 13257-0 to contact a Technical Service Specialist.
