HAMILTON 7000 Series Modified Microliter Syringe

7000 Series

The Hamilton 7000 Series Modified Microliter syringes are used for gas chromatography (GC), thin layer chromatography (TLC), animal injections, and micro-volume fluid transfers. This syringe series is unique, as the sample is held in the stainless steel needle. The tungsten plunger wire travels inside the needle, dispensing 100% of the sample when fully depressed. The knurled hub nut is seated against a sealing ferrule at the junction of the needle/glass barrel to ensure injection pressures up to 41.4 MPa (6,000 psig). To maintain this seal, periodically tighten the knurled hub nut until light resistance to plunger movement is felt. Use of pliers on the knurled hub nut may be required to achieve this tightness. The black PTFE-coated plunger sleeve makes it easy to read the exact volume.

Two sizes of spacers are available to control the depth of needle penetration. A standard spacer (P/N 86203), resulting in a 19 mm (0.75 inch) exposed needle length, and a shorter spacer (P/N 86201), resulting in a 45 mm (1.75 inch) exposed needle length. The spacer also provides a convenient handhold when inserting the needle.

Order 7000 Series Modified Microliter syringes with your choice of two needle point styles. Point style 2 has a 22° bevel; point style 3 has a 90° blunt end. Point style 3 is recommended for transfer pipetting and micro-volumes.

Two accessories are available for use with the 7000 Series Modified Microliter syringes. The Reproducibility Adapter assures repetitive plunger location, while the Syringe Guide aids in preventing plunger bending and accidental removal of the plunger.
