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!

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.

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.

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!

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

Worked very well for the purpose I purchased it for

If your looking to use these for cologne extraction I would suggest looking elsewhere. The cologne does not stay in the syringe because there is no rubber on the plunger to create an air tight seal. The plunger falls down on its own with the cologne inside causing the cologne to fall out as soon as the syringe is pulled off the cologne bottle.

Real professional item will last

After usage of 3 months the liquid starts to leak You need to change it every 3 or 4 months. Other than that it is all good.

The plunger sits loosely in the glass and doesn’t seal. It just flops around and falls completely out when turned upside down. When drawing up a liquid there is no seal to hold the plunger up so it just keeps falling down and you lose everything you draw up. There is no control over it whatsoever. Very disappointed.

Great quality

Llegaron en tiempo y en excelentes condiciones. De relativa buena calidad, resistentes a la presión (negativa y positiva) como cualquier otra de su tipo al no tener embolo de goma el líquido no es retenido y el embolo baja sólo por gravedad (para tomar en cuenta). Ya el tiempo dirá si duran como una de marca.

Product worked well and exactly as described so I was very happy.
