Syringes

[hortense]

As does Dave, I use syringes to measure small quantities of developer for one-shot dilutions. Plastic veterinarian syringes are what I use. With these, I find the plastic and the seal material (rubber?) on the end of the plunger after repeated use stick so that precise adjustments are dificult. Any suggestions would be appreciated. What about the more expensive glass syringes?

I have the same problem, i just buy new ones when needed.

Years ago, a friend that worked in a lab gave me a 20cc all glass syringe. It is wonderful. I fear the day that I drop and break it. It will be a terrible loss.

Syringes for oral administration of children's medicines are available pretty cheaply from drug stores. In my local CVS, they're on the shelves, with no need for a prescription or to ask a pharmacist. (These syringes have no threads for needles, but that's fine for measuring small quantities of developer.) I don't recall the exact price, but the two I bought were certainly trivial purchases. I won't be upset if/when they start sticking and need replacement.

I sometimes have the same problem. I find that running hot water through the syringe and working the plunger several times before use helps to alleviate the problem. Eventually it gets to the point where they are too far gone and you'll have to buy new ones though.

Calibrated syringes designed for refilling ink jet printer cartridges can usually be found at electronics stores and computer flea markets, and are dirt cheap.

I use the kids ones. Never a problem. But I always wash them after use. Nothing fancy just put them under the tap. They come with nice rubber stepped stoppers to fit bottles to. Only problem is some times the rubber stops falls in the bottle :rolleyes:

For years I had used syringes. There is a surplus scientific store nearby and the had pipettes in glass and plastic. The plastic ones were $.25 each. Even easier to use than a syringe.

The Formulary sells a wide variety of syringes including an ultra inexpensive syringe with a bulb on the end to assist in filling it. They are more like inexpensive pipettes and come in a variety of sizes.

I use all sizes and types of their syringes for my lab work. I also use the baby and pet syringes for some purposes.

They are all handy in the lab.

Hi,

Pipettes and Pipette pumps are very handy like ones below

They come in three different capacities, 2ml, 10ml, and 25ml. You just turn the wheel to pick up the solution at desired amount, and push long white button to release it.

By the way, I bought too many pipettes (10ml) if anyone is interested...

Warmly,
Tsuyoshi
