ESR Tube Filling Needles (18G, 6-Inch)

The Apex Labs ESR Tube Filling Needles (18G) are specialized laboratory tools engineered for the precise, bubble-free transfer of anticoagulated blood into Westergren or other Erythrocyte Sedimentation Rate (ESR) tubes. With an extended 6-inch length, these stainless steel needles allow technicians to reach the bottom of slender ESR tubes, facilitating “bottom-up” filling to prevent air bubbles—a critical factor for accurate clinical test results. Supplied by Apex Labs with full GST support for seamless institutional procurement.
