We also carry a large assortment of test equipment, power supplies, semiconductor equipment, large machine tools, industrial equipment, plumbing & electrical supplies, recirculating chillers, electric motors, photo, audio and radio equipment, computer equipment, photo equipment & product instruction and operation manuals.

If you can't find it on our website just give customer service a call and we'd be happy to check to see if we have what you need in stock. Our inventory is updated daily and every item listed on our website is in stock and ready to ship today.

Most of our pre-owned equipment comes from working environments and many items have been tested by a technician. BMI also carries some inventory items that may not be functioning properly. We maintain this inventory to supply the demand of those of you seeking parts for legacy items. These items are priced accordingly, sold "as is" and may not be returned.

We are continually receiving new loads of new and used scientific equipment inventory and our turnover is very high so we have a category on the home page that shows our newest acquisitions.
