The best syringes have the "o" ring type plungers. However, they usually have to be ordered. The syringes you get from your vet are intended for one-time use, so are not going to last long. The "o" rings will last for weeks, working properly. Not a bad idea to order them on-line and keep a small supply on hand. I keep multiple sizes on hand, from 1/2mL up to 40-60mL. I use them for meds, syringe feedings, and sub-q fluids. The printing on the "o" rings also doesn't rub off very quickly. I rinse them out after each use. Then, weekly, I take them apart, put them in a cup with water and put in the microwave until the water comes to a boil. After it cools, I put them on a paper towel to dry. When dry, I rub or spray a little vegetable oil on the plunger and put it back into the syringe, working it up and down until there is a smooth flow. The "o" rings are more expensive so this technique extends their life for a good while. I have used 20mL syringes for weeks, using them 2-3 times a day for feedings. Here are two links. The Squirrel Store sells individual syringes so that may be the best place to get a few of each size. They are called "o" ring there. Med Care Products sells them by the box. I split orders with a wildlife rehabber and this is more cost effective for large orders. They are the Basik brand. http://www.squirrelstore.com/ http://www.medcareproducts.com/ Katharine [Posted in FML issue 5261]
