Fyi,

Syringe brands may vary in quality.  I have used a number of chinese & US brands of plastic syringes, they all react, slightly and the same way to EA. By this I mean, that after a few fills with each syringe, the plunger becomes harder to pull/push, then the tip of the plunger arm pops out of the black rubber gasket-tip.  I haven’t taken the time to determine if the clear plastic tube is warping or the black rubber gasket-tip of the plunger is deforming.  I have used syringes on all my runs and never gotten goo prior to filtering.

I recently switched to glass luer lock syringes, the ones i use have no plastic or rubber components. I have, so far, not been clumsy enough to break them, which turns out to be cheaper in the long run than replacing plastic ones.

You can purchase blunt/indudtrial stainless steel luer lock tips of various diameters to use with them.

Much easier and more versatile than pipettes, imo.
