2in1 KITs contain 100 vials and 100 closures in a blue PP-Box. As both components are always required at the same time, 2in1 KITs are a convenient way to obtain and store all required items for analysis. 2in1 KITs are available for any type of 1.5ml (32 x 11.6mm), 4ml (45 x 14.75mm) or 20ml Headspace Vial (75.5 x 23mm) with an appropriate seal. All advantages of the individual components (cleanroom packaging of the vials, recloseability of the packaging, etc.) remain unchanged.
