(Click to see larger image) The Tritech Research Brass Straight-Arm Needle Holder is compatible with the microINJECTOR™, or any other microinjection system.  Using a simple compression system, it holds microcapillary injection needles from 0.5-1.5mm in diameter.  Customized versions are available for 2.0mm and other sized injection needles.  The standard needle holder shaft is 4mm (5/32 in) in diameter with a total holder length of 140mm (5.5 in) for maximum compatibility with Narishige and other micromanipulators.  Other sizes are available by special order.

The MINJ-4 comes with a quick-connect and tubing but we are happy to customize your needle holder connection according to your needs. Please choose the one you need from the pre-defined choices (see pictures below) or call us at 310-446-4460.
