Dosing very aggressive and corrosive liquids in laboratories is a challenge. Diaphragm pumps are the ideal tool for this difficult task.
The new SIMDOS® 02 FT (full PTFE) has been especially developed for the transfer of aggressive chemicals. To do this, the SIMDOS® 02 FT is fitted with a PTFE head, a PTFE-covered diaphragm, and chemically resistant FFKM Kalrez® valves. An optionally available Chemraz®-valve kit even allows using the pump with highly concentrated acids such as nitric, sulphuric and hydrochloric acids and solvents such as TFH, DMF, DMSO and MEK. The pump head is situated outside the splash-protected IP-65 housing, providing a very significant safety feature.
Also available with heads in PP or PVDF, the new SIMDOS® 02 FT dosing pump transfers liquids with a flow rate of 30 µl to 20 ml/min, and dose volumes of 30 µl up to 999 ml. Following calibration, repeatability is +/-1% (full range) and the pump offers excellent long-term stability and consistent reliability throughout entire processes. The SIMDOS® 02 FT is safe to run dry and is self-priming up to 2 m. It is effective against pressures of up to 6 bar, and transfers viscous media up to 150 centistokes. The integrated software permits the transfer parameters to be modified for a range of different viscosities at the touch of a button. Thanks to its neat design and small footprint, the new SIMDOS® 02 FT dosing pump takes up very little valuable laboratory space.
