BrandTech Scientific Dispensette® S Organic Bottletop Dispensers are precision-engineered instruments designed for the safe, efficient, and reliable dispensing of organic solvents, chlorinated and fluorinated hydrocarbons, concentrated acids (such as HCl, HNO₃, and TFA; excluding HF), tetrahydrofuran (THF), and peroxides. Optimized for demanding laboratory environments, these dispensers ensure contamination-free, reproducible dispensing even under continuous operation.
Key Features:
- Available in both analog and digital models with intuitive adjustment mechanisms
- Handles media with densities up to 2.2 g/cm³, viscosities up to 500 mm²/s, and vapor pressures up to 600 mbar
- Minimal operating forces and ergonomic design for user comfort
- Quick, tool-assisted calibration ensures consistent accuracy
- Designed to operate reliably between +15 °C and +40 °C
- Engineered without recirculation valve for simplicity and optimized organic chemical compatibility
