2Pack 5ml/cc Glass Syringe With Metal Luer Lock and Caps for Liquid, Borosilicate Glass Syringe for Oil or Glue Applicator,No Needle

Breaks easily, get many, but works exactly for what I need and have ordered over 50. I just dispose of them after, but that’s for my use case. 4.5/5 for sure Be careful, be gentle; handle glass like it will break like glass, you will be okay!

Real professional item will last

One syringe came broken and the other one does not work. It doesn't suction correctly, it ends up spilling everything and the tube from inside slides down and ends up falling from inside the syringe.

Perfect for my needs! I wanted a more permanent and reliable option for storing soldering flux. I have been refilling disposable plastic syringes, but ran into a lot of issues with them encountering blockages, as sometimes the flux coalesces into small and this clogs the end. This can be corrected with gentle heat, but many plastic syringes and nozzle attachments simply warp from the required heat! These syringes have corrected this problem. They are also very precise with dispensing and I have not encountered any leaks whatsoever from the plunger or the nozzle. I recommend pairing these with stainless steel luer-lock nozzles of varying sizes.

Worked very well for the purpose I purchased it for

WONDERFUL SYRINGES... until they exploded from adjacent shock forces

I bought the 5ml version. There were 2 complete syringes in my package, and the plungers in both of them fit perfectly. If I plug the tip with my finger and hold the syringe upside down while dry the plunger does not move except for almost imperceptibly slowly as air very gradually seeps in. For glass on glass this is a impressive seal imo. They don't feel fragile to me either as long as they are treated like they are made of glass. No complaints here, would buy again!

Check for leaks where the metal adapter is epoxied to the glass. 20ml 2 pack one had to be re-glued. I used 'super glue' because none of the chemicals I'll be using reacts to it. Other than that seems like a good long term product for my needs.
