Alphaplastic Rubber Conical Cap is a laboratory consumable designed for sealing vials, test tubes, and other lab equipment. Made from durable rubber material, it offers resistance to temperature fluctuations (-8 to +80°C) and chemical exposure. The cap fits 16mm diameter vials and includes a 20-piece pack.
The product maintains its structural integrity under varying conditions but may retain a residual rubber odor, which should be considered for non-lab applications.
