The Watson-Marlow 120U/R, 120S/R and 120F/R compose a 102R quick-change pumphead. This machine is powered by a 120 fixed speed may it be on variable speed or automatic drive.

End users can free up space in the clean room, LAF and biosafety cabinet installations as the 120 pumps are not only small but also stackable. On the other hand, 120U requires manual remote control as well as automatic control via 4-20mA or 0-10V inputs. 120S also operates through manual control with 1-32 rpm in 1 rpm increments. And lastly, the 120F is available in 10, 17 and 31 rpm versions.
