DESCRIPTION: Dispensette® bottletop dispensers improve accuracy, safety and reagent conservation for a broad range of applications. Dispensers mount directly onto most reagent bottles for faster, more convenient dispensing. The innovative design makes for quick, easy cleaning and safe operation. The "floating piston" design is manufactured to close tolerances that eliminate the need for polymer seals that wear out and need replacement. A safety-discharge valve reduces the chance of inadvertent dispensing.
