Handles Critical Solvents
The Dispensette Organic handles your critical solvents: THF, TFA, methanol, acetonitrile, methylene chloride, DMF and DMSO. The instrument is also the right choice for HNO3 and HCl, and peroxides, but is not suited for alkaline solutions or hydrochloride salts.
Enhanced Safety Features
The Dispensette Organic adds this specialized chemical compatibility to the familiar safety and convenience features of the popular Dispensette S, including 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 telescoping filling tube and thread adapters to fit to most lab bottles.
Available in Digital and Analog Models
The Dispensette Organic comes in analog and digital models with bright yellow trim for easy identification. Accessories are available for serial and drum dispensing.
Limitations of use
The parts of the Dispensette Organic which come into contact with the liquid are made of high-grade materials such as ETFE, PTFE, PFA, borosilicate glass, FEP and tantalum. The Dispensette Organic should not be used with any liquids that attack these materials.
Limitations of use (all instruments)
This instrument is designed for dispensing liquids, observing the following physical limits:
- Use between 15°C and 40°C (59°F and 104°F) of instrument and reagent
- Density up to 2.2 g/cm³
- Vapor pressure up to max. 600 mbar; aspirate slowly above 300mbar in order to prevent the liquid from boiling
- Kinematic viscosity up to 500 mm²/s (dynamic viscosity [mPas] = kinematic viscosity [mm²/s] x density [b/cm³])
Operating Exclusions–
Never use the Dispensette® Organic with:
- Liquids attacking PP (screw cap), Al2O3-ceramic, tantalum, ETFE, FEP, PFA and PTFE (e.g., dissolved sodium azide*)
- Liquids attacking borosilicate glass (e.g., hydrofluoric acid)
- Bases and saline solutions
- Explosive liquids (e.g., carbon disulfide)
- Suspensions as solid particles may clog or damage the instrument (e.g., of charcoal)
*Dissolved sodium azide permitted up to a max. concentration of 0.1%
