摘要: An elastomeric plunger tip for syringes comprises a compressible, material having durometer of about 35 to 75 when measured on the Shore A scale and maintains its resilience at temperatures least as low 0° C. The is provided with peripheral annular wiper lip extending axially forwardly radially outwardly into sealing contact syringe barrel.
