Weld-on 25-Gauge Precision Syringe Applicator for Weld-on 3 and Weld-on 4 Acrylic Solvent Cement - Pack of 3

In the first try that i was gluing with acrylic cement the plunger started melting and the needle clogged easily, the cheap ones last longer, DO NOT BUY! WORST PRODUCT THAT I HAVE BOUGHT ON AMAZON!

Careful with needle, brakes off easily, but otherwise worked well.

Finally! Syringes are back! If you glue up a lot of plastics, especially acrylic, nothing is worse than a leaking, dripping, and "unable to hold a vacuum" applicator bottle. Back in the day we always used syringes (which we picked up at the local drugstore). These afford you much more control in application of the thin "welding" adhesives without any chance of drips as they indeed hold that good vacuum. And it is kind of nice to not have to deal with the sharpened points. Suggestion: buy the ones with the smaller gauge needles.

they put the needles inside the gap between the plunger and the syringe, which does not keep them in place; the needles fall out and anyone handling the package runs risk of serious injury. not cool.

These require so much force to operate that it is very difficult to fill them and to dispense a small amount of glue. I finally gave up trying and just used the solvent out of a squeeze bottle.

Horrible. They're sucking up air, SO HARD to squeeze, not easy to depress at all, squirts all over the place......

I lube the red plunger part with PTFE prior to use. This eliminates the rubber breaking off in bits and getting stuck in the needle. The when finished I run DNA through it and store it disassembled.

The plunger melts in an hour and is no longer able to be used
