We stand behind the technical specifications of our products and the quality of their manufacture; defective goods will be replaced if returned promptly or fully credited if replacements are unavailable.
However, our market is first and foremost science education & related R&D & because of the nature of these endeavours, scientific results cannot be guaranteed. We cannot take products back due to poor experimental design.
Call first if you have product questions. If we have doubts about your design or feel our products might not suit your needs call us first & we will advise you. It is cheaper for both of us for you to not buy then have you return it!
Goods may NOT be returned w/o authorization.
A restocking charge of 20% or $10.00 whichever is greater will be applied; shipping not included. Goods that are opened will be evaluated for their resale value and may be assessed a 50% restocking charge.
It takes approximately 5 business days after receipt of goods to issue credit.
Some goods may be returned for exchange, e.g. magnifiers, at no penalty except for additional shipping charges. Other items such as molecular models will be accepted if returned promptly and are unopened.
If a technical specification or description is wrong or ambiguous such that it has clearly compromised the success of your experiment, we will gladly refund ALL your costs.
Glassware cannot be returned for any reason; this is for your safety and ours. It would be prohibitively expensive to test for bacteriological, chemical or radiological agents since there is no way to tell if glass has been contaminated just by looking at it. We would have to throw it away even if you claim to never have opened the package.
