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

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!

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!

Ours cracked during first use. All that happened was my wife placed it on the counter. It wasn't dropped. I feel that means the glass is under tension which makes it so fragile IDK what to tell you. But even worse is that the suction seal was not tight enough so it leaks easily under no load - it's not effective. Avoid, total waste of money and even before it broke it wasn't effective at sucking up liquid. The only positive is that it is 100% glass.

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.

This is an all glass syringe and the only issue i have is the plunger doesn't stay in place after filling it First time I used it because I had it filled all the way everything came right out cause the plunger didn't stay in place. Also you don't want to hold by the plunger after filling cause of the plunger not staying in place the bottom part of it came off as the plunger stayed in my hand.

Works well

love being able to autoclave culture syringes without worry of melting or filli g up a landfill with plastic syringes. problem with these despite being grest glass is that they leak a bit around plunger and require a luer cap until youre ready to go with an innoculation otherwise they will discharge content unless kept completely level when hypodermic is on or they have no cap on them. have to nearly strong arm your cap or hypodermic on otherwise they will leak at connection when discharging. if there were some kind of gasket on the plunger these would be 5star

Good for boofing water soluble drugs like cocaine so they absorb faster and don’t mess up your nose. Needles impossible to get but why do you even need them?

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.
