Please contact us via phone or e-mail to request samples of our materials to evaluate in your own test systems. We provide 0.5ml samples free of charge and request that you evaluate the samples within two weeks. If you need additional time for further evaluations, please contact us.
In addition, it is helpful to provide us with your purchase specifications (such as serum vs. plasma, titer requirements, acceptable preservatives and/or anti-coagulants) and shipping preferences (such as frozen vs. not frozen, type of delivery services and delivery company). We keep copies of all of our customers’ purchasing/shipping specifications in order to customize the selection of materials for your use.
While we do not utilize catalogue numbers, we do assign donor ID numbers and individual identification numbers to every bleed in order to trace all of our materials. We also supply additional information such as volume, form, bleed date, anticoagulant, preservative and viral marking testing on the COA. Upon request, demographic information is also available for most donors.
In general, we adhere to a 14 day return policy. However, we will also purchase back disease state plasma, serum or control as long as it has been stored frozen and not adulterated. Furthermore, we purchase any overstocked inventories, even if initially purchased from other sources. If you have questions about this buy-back program, please contact us.
