Cryogenic Vial w/Plug Seal - 2 mL (2 mL)

Internal Threaded Vials; Type: Self-standing; Ideal for a variety of cryogenic storage applications including cell and microbiological cultures, serum/blood, or other biological materials. Made from specially formulated polypropylene for extra durability, these vials withstand temperatures as low as -190°C (-310°F). A silicone washer inside the cap forms a tight, leakproof seal. And, since both cap and vial are made from the same material, any expansion at extreme temperatures will affect both parts equally, so seal remains secure. Available with either internal or external threads for attaching cap.

• Plug seal cap provides secure seal
