2Pack 10ml/cc Glass Syringes With Metal Head and Caps for Industry or Labtoratory

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.

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.
