This occurs when the sample/solvent dries from inside the syringe and leaves behind sticky residue, which basically “glues” the plunger to the barrel. To fully understand why this happens, think about how a syringe works.
Can oral syringes be reused?
Throw out oral syringes after each use with chemotherapy. For all other medicines, you can wash and reuse oral syringes unless the clinic doctor or nurse tells you otherwise.
Do you need to replace the air button on a syringe?
If not, you will need to replace the button (or valve core, if your syringe uses valve cores). As a temporary fix, you can swap the air and water buttons of your syringe. This will cause the air button to stick, but this is often less problematic than having the water constantly leak.
Why is my air and water syringe not working?
If the buttons are not sticking, the problem is likely inside the syringe head. There is a small o’ring inside the syringe which keeps the air and water separate (the “small adaptor nut” o-ring part 01-06 ). This o-ring could be worn or missing and should be replaced.
What to do if your syringe keeps leaking water?
As a temporary fix, you can swap the air and water buttons of your syringe. This will cause the air button to stick, but this is often less problematic than having the water constantly leak. See our previous issues on syringe repair for step-by-step instructions on removing and changing buttons.
How often should I change my water syringe frequency?
We recommend once a month, but you may want to adjust the frequency depending on your conditions and experience (e.g. if you have particularly hard water, a greater frequency may be warranted). Lubrication may be enough to restore proper function.
