0.5 µL, Microliter Syringe Knurled Hub (KH), PN: 86257 Details

Hamilton's 7000 series, Microliter #7000.5 Knurled Hub (KH) Syringe, 32 gauge, is designed for manual dispensing and use in autosamplers.

The 7000 series syringe offers unmatched accuracy – it's the only true zero-dead volume syringe on the market. Our innovative plunger-in-needle design, featuring a fine-gauge tungsten plunger wire extending to the very tip of the needle, guarantees complete solvent delivery, eliminating waste and maximizing the value of your precious samples. Due to this plunger-in-needle design, it is not recommended to remove the needle or plunger. Hamilton syringes ensure an accuracy of ± 1%, superior durability, and are manufactured with the highest quality chemically resistant materials.

Please see the 7000 Syringe Series Operating Parameters for complete specifications.

Common applications Veterinary Sciences, Analytical Chemistry, Gas Chromatography Mass Spectrometry (GC-MS)

Plunger-In Needle Design

  • Features a fine tungsten plunger wire extending to the tip of the needle.
  • This design creates a true zero dead volume syringe, maximizing sample utilization.

Borosilicate Glass Syringe Body

  • Provides chemical durability and long-lasting syringe performance.
  • Maintains accuracy and precision over a wide range of temperatures and pressures.

  • Precise Micro-injections with Zero Dead Volume

    In invertebrate model organisms, I prefer Hamilton syringes in my studies because of the low margin of error, no dead volume, and customizable tip options for innate immunity or survival etc.
