What LDS Vacuum Shopper does

LDS Vacuum Products, Inc. (DBA LDS Vacuum Shopper) is a Longwood, Florida-based, 100% woman-owned specialist distributor of high vacuum (HV) and ultra-high vacuum (UHV) components, established in 1973. The company sells standardized and custom vacuum hardware — including Conflat, NW/KF/QF, and ISO flanges, valves, pumps, feedthroughs, bellows, gauges, and thin-film supplies — primarily in 304 stainless steel, with extensive overstock and surplus inventory offered at discounts of up to 76% off list. Its proprietary branded product is the LDS Leak Tracer, a helium/hydrogen leak detector priced at $22,000 with a 2-year warranty and 3-year ion source warranty, available for sale or rental, complemented by A2LA-accredited (Certificate 1566.01) calibration and pump-rebuilding services.

The business operates with no outside sales force, generating demand through referrals, an e-commerce catalog at ldsvacuumshopper.com, email marketing, organic search, and an annual printed catalog. Distribution is direct (phone, fax, email, and online order) with Net30 credit terms available to US customers and international sales handled through an export questionnaire. Customer segments span university and government research labs, industrial vacuum-system manufacturers and integrators, semiconductor and thin-film users, and leak-detection service technicians. The company holds a Woman Owned Small Business (WOSB) certification with CAGE CODE 0XAX4 and UEI JEZVN4KFLKM3, and operates a related sister brand, LDS Custom Nipple Fabricator, for custom-length ISO nipples.
