The BRAND® Dispensette® S Fixed Volume Bottle-Top Dispenser (5 mL) delivers consistent, repeatable liquid dispensing directly from reagent bottles, supporting efficient laboratory workflows while minimizing chemical exposure and reagent waste.

This fixed-volume model is designed for applications requiring a single, precise dispensing volume without adjustment. By eliminating variability associated with manual volume setting, it is ideal for standardized protocols, repetitive dispensing tasks, and quality-controlled workflows. The 5 mL volume is well suited for routine laboratory operations such as reagent addition, sample preparation, and general analytical procedures. The unit is compatible with a wide range of laboratory chemicals, including acids, bases, and solvents.

Equipped with a recirculation valve, this configuration allows reagent to be returned to the source container during priming, reducing waste and improving safety when handling hazardous or high-value chemicals.

Fixed-volume bottle-top dispenser with recirculation valve for precise 5 mL liquid handling. Designed for consistent workflows and reduced reagent waste.
