An intermixing syringe provides means for the isolated storage of two components prior to their being mixed which is usually just before injection of the product. This syringe has an outer barrel and a hollow plunger slidable therein with the barrel portion forward of the piston providing one chamber and the plunger providing the other chamber. The plunger is provided with a piston having spaced, ring-like sealing surfaces and a fluid passageway extending from the interior of the plunger to the outer piston surface. The barrel of this syringe is formed with a straight-bored inner surface and includes no undercuts. The forward most sealing surfaces or end of the plunger piston is disposed to be moved from a sealing condition into a fluid flow or conducting condition to permit flow into the forward portion of the barrel.
