Dispensette® S - the new generation bottle-top dispenser
The best Dispensette® ever - improvements in nearly every detail:
- Extremely easy filling and dispensing
- Simple priming by optimized flow channels
- Rapid and safe volume adjustment with internal scalloped track
The right bottle-top dispenser for each application: Dispensette® S, suitable for an amazingly broad range of applications, particularly for many acids, saline solutions and organic solvents. Dispensette® S Organic, ideal for dispensing of organic solvents and acids. Dispensette® S Trace Analysis, specialized for dispensing high-purity acids, bases and H2O2.
Three different approaches to volume adjustment
Digital: The mechanical volume setting is easy to read and ensures accurate and reproducible volume control. Easy Calibration Technique for calibration adjustment in seconds without tools. A calibration flag indicates changes from factory settings.
Analog-adjustable: Rapid and safe volume setting with new internal scalloped track. Simple calibration adjustment with a supplied tool.
Fixed-volume: For standard applications. Simple calibration adjustment with a supplied tool.
