MiniCollect Capillary Blood Collection Tubes

When a full venipuncture isn't practical — pediatric patients, geriatric draws, difficult veins, or point-of-care testing — Greiner Bio-One MiniCollect tubes let you collect a diagnostic-quality specimen from a simple fingerstick or heel prick. This collection centers on the microtube system trusted by labs and clinics for small-volume capillary sampling where every microliter counts.

The featured tube is the MiniCollect Serum tube (450472): an 11 x 40 mm polypropylene microtube holding 800 µL, with separator gel and a silicone-coated interior to promote clean clot separation and reduce cell adhesion. The gold cap identifies it as a serum-separator tube, matching the familiar color-coding of full-size blood collection systems so your workflow and additive recognition stay consistent. Its rubber cross-section cap seats securely to limit leakage and evaporation during handling and transport, and the tube is non-sterile — standard for capillary specimen collection.
