Glass Syringe 50ml (Per Pack 3), Tomopal Glass Syringe 50 ml, w/1.0 ml Graduation for Laboratory Uses. P/N: 130-4550-X003

Received 3 beautiful glass syringes. Tested one with a luer lock needle and water just now and everything works as expected. Didn't notice any problems such as leaking. Great quality. Everything is glass except the luer lock. The plunger is ground/frosted glass and the inside of the barrel is as well. The plunger has a flat end to prevent itself from rolling off the table. No O-ring to mess with. I'll update if I learn anything new.

These are very high quality. I was resisting the expense, but after throwing away hundreds of sticky plastic syringes, I decided it was worth the risk. There are no rubber gaskets to wear out. They are thick glass. The syringe slides smoothly. Get them.

The Metal Tops Come Off Easily With Thicker Oils Beware !!!!

Use these to make confections at home. Buying plastic ones and then having them exposed to a hot solution would make them go bad quickly, these glass ones are perfect. Not effected by heat (of course they get hot) and much better than buying a ton of disposables

I really like these needles. They are smooth to dispense liquids, air tight, luer lock universal, luer cap universal, sanitize at 250 + F without bending & very heavy as so that 1. They do not break & 2. As so that they depress on their own which makes multiple injections very simple & user friendly...

High quality syringes, flanges slide smoothly

The Tomopal Brand is now my go-to supplier.

Nice quality, reasonable price. When I had questions their support team was excellent.
