Common Needle Assemblies


Probe Point Needle

Also known as pipetting or blunt needles

These labware staples are used extensively in chemistry, biology and medicine research. Pipetting needles work equally well with either manual dispensers or precision automatic volume pipettors. Hub design offer comfortable handling and easy cleaning for reuse. The hubs comply with ANSI and ISO 594/1 and ISO 80369-7 TAPER ONLY specifications and tubing is medical/laboratory grade stock meeting ASTM-A908 requirements. Domestically manufactured.

Non-Coring Needles

Also known as Deflected Tip or Huber Needles

These precision ground stainless steel needles are deflected behind the lumen so the primary bevel is approximately parallel to the needle shaft axis. The non-coring needle design helps to reduce coring upon penetration into septa, film, tissue, rubber and membranes. These familiar labware syringe needles can be used with any lab sampling equipment or dispensers using the standard Luer Lock system.

Typical applications where a non-coring needle would be used include chromatography and micro samplings. The hubs and fabrication comply with ANSI and ISO 594/1 and ISO 80369-7 TAPER ONLY specifications to ensure highest quality and universal compatibility. Tubing complies with medical and laboratory grade ASTM-A908 specifications.

Emulsifying Needles

This double female Luer Lock construction allows micro-emulsification of different viscosity compounds through pressure applied by Luer Lock syringes attached to each end. By repeatedly mixing liquids or slurries back and forth through the common needle, a consistent, uniform mixture will be obtained. The hubs comply with ANSI and ISO 594/1 and ISO 80369-7 TAPER ONLY specifications to ensure highest quality and universal compatibility. Tubing complies with medical and laboratory grade ASTM-A908 specifications. Careful handling eliminates the need for costly, superfluous reinforcement bars.
