2.25ML Borosilicate Glass Syringe with Silver Metal Plunger | 10 Pack | Anti-Leak Luer Lock Syringe without Needle | Accurate Measuring for Liquid, Glue, Oil w/ Borosilicate Glass Tube

I have zero complaints about these little guys! They are strong and have a good and sturdy feel to them. The seal holds well and the plunger is much smoother than plastic syringes. The plunger is metal, which I prefer. Will buy again when needed!

These are exactly what I needed. the suction is on point. They heat and dispense icky sticky resin with ease. They are ready to be coupled with a luer tip needle. (I suggest fully stainless if you're working with sticky stuff that needs to be heated and metered) The luer lock is(TPU?) plastic and is both the lock and a silicone(?) lined cap. No plastic touches your material, it just anchors the needle. The syringes and plungers are very cleanable.( I dont have an autoclave) the plunger is actually two metal pieces, the bottom of the plunger with the o-rings. The chemist in the house squeeled with delight at these. If you're the type of nerd that loves chemistry glassware, you may understand.

They are well made, clear measurements, good seals. Hard to draw back if using thinner sized tip.

I bought these needles to use to measure the resin liquid and it works good with that, easy to clean , little heavy but it's okay . The delivery was fast and worth my money.

Took way to many tries to find this. So glad I did. Works so well I don't know how to feel. This is by far a superior product.

Very minimal leaking that gets past the plunger. Not a big deal really.

These are the best I've ever used. Can't beat the plunger is made of metal. They heat up great and no parts melted. I haven't had any problems. The plunger doesn't melt also.

Tips are plastic. Not a big deal. Thet work for what I need.
