The needle on the photo above is made by joining a columnar part to an end part of a pipe for making a blind-needle point by grinding, with a side hole connected through into the pipe. This structure prevents a fragment of rubber plug invading into the needle. Furthermore, the slanting side hole allows the needle to suck liquid from the closer point to the needle tip so that effective sampling of specimens or reagent is possible. A wide variety of material such as Titanium, SUS, or hastelloy are available for this needle.

Bore polishing and other tip shapes than on the photo below are also available. Please inform us for your requirements.
