Cole-Parmer® VapLock™ Closed Systems Provide Safer HPLC Workplaces

VapLock Closed Systems offer a mechanical means to reduce exposure to volatile organic fumes and hazardous waste solvents


Cole-Parmer VapLock Closed SystemsFebruary 23, 2018, Vernon Hills, Ill.— Scientists, chemical hygienists, and researchers worldwide who work with high performance liquid chromatography (HPLC) and similar liquid-based technologies can get reliable protection against harmful chemical vapors with VapLock Closed Systems for solvent delivery and waste containment. They safeguard technicians and the environment and help maintain compliance with government safety regulations and laboratory best practices. VapLock Closed Systems also regulate solvent extraction, maintain the pressure equilibrium and control evaporation of the mobile phase, facilitating more repeatable analytical results.

Critical analytical instruments, such as HPLC, commonly use organic solvents. Reagent and collection vessels are often left open or ineffectively closed with films and aluminum foil, venting potentially toxic vapors to the atmosphere. VapLock Closed Systems offer a mechanical means to reduce exposure to volatile organic fumes and hazardous waste solvents.

VapLock Closed Systems are modular and versatile, with a full range of available options to adapt to most any equipment setup including a variety of materials for chemical compatibility and multiple port connections and bottle cap sizes.
