drawing needle

**tinymuscles** · 05-27-2021, 05:23 PM

I noticed my 18 gauge drawing needles are EXTREMELY slow to come out… and have a foam type look to the test once it’s in the syringe. I realized that the drawing needles are filtered needles… Should I continue to use these or scrap them for unfiltered ones

Nothing wrong with the filtered ones, but not really useful unless you're dealing with amps and are clumsy with snapping off the top.

Make sure you're pushing in the amount of air equivalent to the amount you're removing. Filtered will draw slower.

I wouldn't just throw them away, they're not going to ruin the gear. Next time just get the regular kind. You might want to heat up the vials in some warm (not hot to the touch) water. It'll make it a little less viscous and easier to pass through the filter.

thanks for the tip!
