Brandtech Dispensette Organic Bottletop Dispensers are the solution for handling organic solvents, concentrated acids and peroxides. The “floating piston” design eliminates the seals that often wear and fail on other dispensers. They have a reinforced discharge tube with threaded safety cap, SafetyPrime valve to conserve solvents and reduce "spurting" while priming, safety discharge system to reduce the chance of inadvertent dispensing, and a telescoping filling tube and thread adapters that fits most lab bottles.
Adjustable Volume Analog Dispensette Organic Models feature a sliding pointer for volume adjustments. Calibration adjustments are made using the provided calibration tool.
Digital Easy Calibration Organic Models enable accurate and reproducible volume setting with an easy-to-read display and a convenient adjustment knob. Simply turn the knob to the desired volume setting. The mechanical digital display indicates the set volume.
All units have a standard 45 mm thread plus additional adapters for other bottle sizes (units ≤10 mL have 24, 28, 33, and 38 mm adapters; units >10 mL have 33 and 38 mm adapters). Units include discharge tube, telescopic filling tube, mounting tool, certificate of performance (with serial number), and operating manual.
Use for safe, convenient dispensing of organic solvents, HNO3 (up to 70%), HCL (up to 37%), peroxides, concentrated acids, THF, TFA, DMF and DMSO
