I get asked often about what needles I use for fine-needle biopsies.  I order about 10 cases at a time of these and that lasts about 6 months.  I have underlined the ones I use from the list of possible ones that Air-Tite sells.  The phone number for the company is at the bottom of the page.  They’re very high quality and produced in Japan.

In my experience, the longer needle length and thus longer needle passes seem to produce a higher quality sample than shorter needles.
