ELITech Group ESR Vacuum Tubes & Blood Collection Supplies

ELITech Group supplies the diagnostic laboratory and phlebotomy market with Excyte vacuum tubes engineered specifically for erythrocyte sedimentation rate (ESR) testing. If your lab runs ESR panels to screen for inflammation, infection, or autoimmune activity, the additive, draw volume, and closure type of your collection tubes matter — and this is a category where consistency drives reliable results.

Both Excyte tubes carried here use a sodium citrate additive with a black closure, the recognized standard for sedimentation rate testing. The choice comes down to material and draw volume. The Excyte glass ESR tube (EX-50205) is a sterile 8 x 120 mm glass tube with a 1 mL draw and conventional closure — a good fit for facilities that prefer glass for its clarity and inert surface. The Excyte plastic ESR tube (EP-10605) offers a 120 mm translucent plastic body with a 1.36 mL draw and conventional closure, reducing breakage risk during transport and handling while remaining sterile.

A common question from purchasing staff: what fill volume should you order? The tube's citrate-to-blood ratio is fixed for the marked draw, so matching the tube to your analyzer and workflow keeps that ratio accurate. Underfilling or overfilling either format can skew sedimentation readings, so buy the volume your protocol specifies and store tubes within their labeled shelf conditions.

These are single-vendor diagnostic consumables, so we recommend ordering by SKU to guarantee you receive the exact additive, closure, and dimensions your lab has validated. HonestMed can help you standardize your ESR tube inventory across sites and reorder in the case quantities your volume demands.
