WHEATON 844002

These chemically inert bottle-top dispensers feature a series of permanently calibrated stops that provide quick and accurate volume selection. Calibration is easily adjusted in the laboratory for temperature or viscosity changes. The volume display is adjustable to four positions for optimal user viewing and ease of setting. The airflow orifice can be modified to accept a membrane filter that eliminates aerosol contamination. The syringe barrel is encased in a protective sleeve, preventing breakage and eliminating spills. The dispenser is autoclavable when fully assembled and easily disassembled for cleaning. Without adapters, dispensers fit a 33mm screw thread bottle.

Supplied with adapters to fit bottles with 25, 28, 38, and 45mm screw neck. Reservoir bottle not included.
