Brinkmann Bottletop Dispensers

The Brinkmann Bottletop Dispenser and Brinkmann ChemSaver^TM Bottletop Dispenser models offer unique and useful features for the most reliable and convenient reagent dispensing. Adapter and accessories allow connection to almost any size reagent bottle and to meet most applications. Brinkmann Bottletop Dispensers are available in adjustable-volume and fixed-volume sizes covering the volume range of 0.5mL to 100mL.

All Brinkmann Bottletop Dispensers offer the following features:

Unique PTFE 'wiping" piston seal displaces reagent in the cylinder without leaving any residue behind. This eliminates "freezing" due to piston swelling and crystallization of reagent and offers better chemical compatibility

Grooved positive-lock volume adjustment ensures precise setting and prevents accidental changes during use

Unique telescoping filling tube adjusts to fit reagent bottle without cutting

A clear plastic sleeve surrounds and protects the glass cylinder to prevent chemical hazards

A support sleeve surrounds the discharge tubing to restrict tubing movement and to provide safe, accurate dispensing

Dispensers rotate 360° for easy access to volume adjustment at all times and for positioning of the dispenser for safe reagent dispensing

Completely autoclavable without having to loosen valves or disassemble

Certificate of calibration is supplied with each dispenser

All models are serviceable for cleaning and maintenance in the lab. The pistons, filling valve and tubing can be replaced, if necessary, to prolong the life of the instrument

Brinkmann ChemSaver^TM Bottletop Dispenser

User calibratable for fine adjustment of the volume when working with viscous or high-density solutions
The Brinkmann ChemSaver Bottletop Dispenser offers the same features as the basic Bottletop Dispenser with the added benefit of being able to recirculate reagent during priming. This avoids the waste usually associated with preparing dispensers for use.

Accessories-

A membrane filter can be attached to protect sterile solutions from airborne contamination

Drying tube connects directly to the back of the dispenser to protect sensitive reagents from moisture or CO₂

Bottle adapters allow attachment to a variety of bottle sizes. Smaller dispensers, with maximum volumes of 2.5 to 10mL, connect directly to 32mm bottles and are supplied with adapters for 28mm, 38mm and 45mm bottles. Larger dispensers, with maximum volumes of 25 to 100mL, connect directly to 45mm bottles and are supplied with adapters to fit 32mm and 38mm bottles. Adapters are available in polypropylene for use with most reagents and PTFE for use with strong acids, strong alkalis or aggressive reagents.
