Most research is dependent on the transfer of measured volumes of liquid or a sample. This transfer technique is often employed up to several times per hour. Laboratory dispensers provide a simple means of storing and dispensing liquid and other materials in the laboratory. Common lab dispensers include bottletop dispensers and burettes, which are available in a variety of types including analog, digital, rotating, reciprocating, and adjustable. A lab dispenser varies in available volume range from as small as 0.2 microliters up to 100 milliliters, depending on the model. A laboratory dispenser is user friendly and can be comfortably suited to most applications.

| Description | Accurate Reagent Dosing- Eliminate Influence of Air Bubbles
- Increase Accuracy
- Save Time
- Save Reagent Cost
- Increase Safety
A titration is only as accurate as its reagent dosing system.

TOP-DOWN DISPENSING
Increase accuracy by eliminating bubbles in tubing.- Piston moves from the top–down
- Because dispensing occurs from the bottom of the buret, air bubbles are eliminated
PROTECTED DRIVE MOTOR
Save money by eliminating equipment damage due to spills and buret leaks.- Drive mechanism and electronics sit above reagent so spills or leaks will not drip into vital components
- Your equipment—and you—are protected!
SMARTCHIP TECHNOLOGY
Save time by never titrating with the wrong or non-standardized reagents.- Automatic recognition of the titrant’s serial number, ID, buret volume, standardization history—including control charts and limits
CHEMICAL SAFETY
Increase safety by reducing operator contact with chemicals.- Dosinos can be directly connected to almost any type of reagent bottle or chemical storage container
- No need to pour reagents anymore!
1-TOUCH RINSING
Save time by quickly and efficiently changing reagents.- 1 simple touch translates to zero dead volume and super-quick reagent changeover
1-TOUCH REAGENT EMPTY
Save time and money with a clean, ready-to-use dispensing system.- 1 simple touch empties the reagent back into the reagent bottle
- Eliminates crystallization of reagent in buret and tubing

They are ideal for dispensing aliquots of liquid from large supply bottles−extracting reproducible dispensing volumes without reagent waste. They also Brinkmann bottletop dispensers and ChemSaver dispensers offer you unique and useful features for reliable and convenient reagent dispensing. They are ideal for dispensing aliquots of liquid from large supply bottles−extracting reproducible dispensing volumes without reagent waste. They also ensure the best possible protection for you and your laboratory when working with caustic liquids such as solvents. For the utmost in safety, they feature extremely high chemical resistance and can be autoclaved (20 min, 121°C).
Every dispenser is supplied with three adapters.- Smaller dispensers−with volume settings from 2.5 mlto 10 ml−connect directly to 32 mm threaded bottles and are supplied with adapters for 28 mm, 40 mm and 45 mm bottles
- Larger dispensers−with volume settings from 25 ml to 100 ml−connect directly to 45 mm bottles and are supplied with adapters to fit 32 mm, 38 mm and 40 mm bottles
A wide range of adapters and accessories are available to expand your applications.
Features- Telescopic filling tube adjusts to fit most reagent bottles without cutting
- Rapid volume setting using precise graduation scale
- Support sleeve surrounds the discharge tubing to restrict movement−provides safe, accurate dispensing
- Dispenser rotates 360° to position the dispenser for easy and safe reagent dispensing
- Volume adjustment sleeve also rotates 360° to provide visibility to volume settings at any time
- Fully autoclavable without having to loosen valves or disassemble
- Modular construction allows simple cleaning and maintenance
- Adapters and accessories allow connection to almost any size reagent bottle
- Available in adjustable- and fixed-volume sizes covering the range from 2.5 to 100 ml
