Made from Cyclo Olefin Polymer (COP) the Medallion syringes are offered with either an ABS or PC plunger. The 20 ml syringes are available in an array of colors and come with a silicone plunger tip. The ABS plunger version is BPA-Free, while the PC plunger has a high heat resistance and is compatible with steam, gamma, or ETO sterilization. Both have excellent purity and extremely low residual metals (less than .02 ppm). A 1 ml syringe in blue is also available with either a PC or ABS plunger. They offer good chemical resistance to acids, bases, alcohols and fragrances. Color matched polycarbonate caps are available to match the syringe plunger color. Pad printing on the barrel to custom sized and colored plungers are also available.
