Description
The BD® 309653 is a high-capacity syringe (officially graduated to 50 ml with a 60 ml total capacity) engineered for the precise measurement and secure delivery of large fluid volumes in non-human research and engineering environments. This syringe features an integrated BD Luer-Lok® tip, providing a threaded, “locked” connection that prevents accidental needle or tubing detachment—critical for high-pressure applications or the transfer of high-viscosity reagents. Constructed from medical-grade polypropylene, this syringe is an essential tool for benchtop fluidics, large-volume sampling in field research, and the calibration of industrial liquid-handling equipment.
Technical Performance and Design
-
Secure Luer-Lok Connection: Features a high-integrity threaded hub that locks needles and tubing sets firmly in place, ensuring a leak-proof seal essential for pressurized fluidic R&D.
-
Large-Format Volumetric Accuracy: The barrel is imprinted with bold, high-contrast scale markings in 1.0 ml increments, ensuring precise readings for large-scale dosing or reagent preparation.
-
Tapered Plunger Rod: Specifically designed for ease of aspiration, the plunger includes a positive rod stop to prevent accidental pull-out during maximum-volume draws.
-
Pressure-Rated Integrity: Engineered to withstand standard laboratory pressures (typically up to 29 psi), making it suitable for manual infusion and filtration protocols.
