Hamilton Company offers the most comprehensive selection of standard and custom syringes in the industry

Each is manufactured to achieve the highest level of accuracy and precision possible. Threaded plunger syringes are for applications requiring extremely precise plunger movement or minute fluid manipulation. The Luer tip (LT) syringe terminations allow easy connection of Kel-F® hub needles; Kel-F® hub PTFE tubing; and 1/4" O.D. x 1/8" I.D. Tygon® or rubber tubing. This series of syringes is ideal for dispensing volumes from .33 to 13.23 µL per plunger revolution depending on syringe volume.
Gastight® syringes are ideal for dispensing both liquids and gases. They have a precision-machined PTFE plunger tip which creates a leak-free seal. With the tight fit, the tip essentially wipes the interior of the syringe barrel free of sample. This feature is particularly useful with heterogeneous samples as it reduces the chance that a deposit will occur and cause the plunger to freeze.

Threaded Plunger Syringe Terminations:

Luer Tip (LT)- The needles are removable and fit over a ground glass hub which is tapered in the shape of a male luer. The LT termination will accept most hypodermic needles but was designed specifically for use with Hamilton Kel-F needles. This termination increases the dead volume in the syringe, which may not be appropriate for some applications. Autoclavable when disassembled.

Needle Point Styles (Purchase Kel-F Hub Needles Seperately):

Point Style 2 - Sharp, beveled, curved, non-coring needle point recommended for septum penetration. Available gauges: 31-10. Point Style 3 - Blunt needle point for use with HPLC injection valves and for sample pipetting. Available gauges: 31-10. Point Style 4 - Standard 12° beveled needle point is recommended for life science applications. Available gauges: 31-10. Special point styles such as 30°, 45°, or any other angle are available upon request. Point Style 5 - Conical needle with side port for penetration of septa, thin-gauged vinyls and plastics without coring. Available gauges: 26-10. Point Style AS - Special conical style needle point used on autosampler syringes the non-coring needle point is recommended for septum penetration. Available gauges: 26-22.
