Other Resources
Places outside Citron to buy stock parts, find a supplier, or shop a marketplace.
Large single-vendor stock catalogs
- Qosina — 5,000+ off-the-shelf single-use OEM parts (luers, stopcocks, hubs, valves, tubing, kit components). Free samples, drawings/CAD, low MOQs. Less “catheter shaft materials,” more fluid-path and disposable hardware.
- Nordson MEDICAL — Direct storefronts for extruded tubing, PET/FEP heat shrink, balloons, nitinol, and Value Plastics-style fluid fittings. Mix of stock and custom.
- McMaster-Carr — Not medtech-only, but still the default for o-rings, fasteners, raw stock, fittings, and lab-grade tubing when you need it today.
- Cole-Parmer / Thermo Fisher — Lab and bioprocess tubing, fittings, and fluidics; useful adjacent to device work, weaker on interventional catheter SKUs.
