    You people are probably way ahead of me but I picked up one of these in a local Eckerd Drug Store to replace the old hard to read 10ml oral syringe that I used to measure small quantities of Rodinal. This has the coolest lttle system for getting the solution from the bottle into the syringe. Too nice a little $2.50US darkroom problem solver not to share. I must find a 20ml and 30ml that will worrk with it.

    Got me two of them little puppies. One marked chemicals and stored properly and the other marked baby and kept with his stuff. The baby section of your local mega mart is a great place to find darkroom supplies.

    Being a batchler and having no children. I have to wonder what you would do with a syringe and a baby? :confused::smile:

    Nifty device. I'l admit that I'm still using the syringes I got back in the '60s, when Rodinal came with rubber stoppers, and you were expected to extract it that way.

    Very timely suggestion.

    I've been up all night with a lousy cough so I'm heading down to Eckerd's this morning for an assortment of medications. I'll have to check out this device.

    I just recently bought my first bottle of Rodinal in years. I haven't used it yet. I was astonished to discover it's now in a plastic bottle. And you're telling me it no longer has the rubber stopper!? What's become of tradition? :rolleyes:

    I dug around my darkroom supplies and found a couple of old veterinary syringes I used 30 years ago with Rodinal. This looks like a better method than those.

    The least costly but effective are syringes from a vetenary supply house.

    This only cost Two and a Half bucks and I have a local drug store but not a local veteranary supply house :smile: Unfortunately 10ml seems to be the only size.

    I found cheap syringes at my local Tractor Supply Company (TSC) in the animal care section. Sizes 3ml to 35ml. A couple of dollars for a 6 pack of the smaller sizes. They also have some needles if you have an old bottle of Rodinal or Neofin Blau, or need to reach further down into a bottle. Wish that would work with undiluted TEA stocks. Gluuuug.... Gluuuug....

    35ml would be a nice size to have. Great for pulling an ounce of FG-7.

    The big ones are either in a vet-supply store or in a place for people with renal problems, they have to use those big suckers (up to 50ml)

    I've been using a 10 ml plastic pipette. It works great for small amounts of PMK A & B to make 300 ml working solution. This one is configured so you fill it with a bulb and release the liquid till it measures 0. It is full then. By removing your finger tip you release a small stream until the level reachs the desired amount, 3 or 6 up to 10.

    I bought one. Looks to be very useful. I'll give it a run this weekend.

    You just need a wider (larger gauge) needle.

    The local supermarket/drugstore stocks 5ml and 10ml. Plus they've got little droppers in 1ml size that's marked in 1/4 ml. The digital thermometers are good for checking the accuracy of the faster darkroom one.

    Ask the pharmacist(sp) about the bigger syringes. They may ask you what you are using them for but I have not had a hard time getting the big ones after telling them what I want it for.

    That's the trick. TEA won't even think about starting up an 18 gauge needle, even heated a bit. The horse and cow needles at TSC (Tractor Supply Company) don't get over 16 guage. I'm looking around to see if there's a PSC nearby (Pachyderm Supply Company). Barring that, I was acquainted a few years back with someone who is now a vet for the large African animals at the Bronx Zoo. Maybe she can get me something. :smile:

    Until then, I decant TEA stock solution into a film can to draw it up into the syringe, which is a little wasteful, as I can't get it all to flow back into the storage bottle. I'll try one of the baby syringe bottle stopper/adapters. I've used them before, just not with TEA.

    I don't understand. Why would you be able to draw TEA into a needleless syringe from a film can but not using the stopper system? It would seem to be a perfect solution to the wastefulness of putting it into to the can before drawing it.

    The storage bottle I use for TEA is too narrow for the syringe body to enter, so I have to decant to a film canister for a wider mouth. As I said, I haven't tried the baby syringe stopper on the TEA storage bottle yet. I plan to.

    I see. Let us know how it works. I've been fighting the urge to try PC-TEA for a while but if I ever cave in, it will be good to know.
