Controlled AlfaDos™ Dropping Funnel

Like a traditional dropping funnel, the innovative AlfaDos™ dosing system is simply driven by gravity and does consequently not require any pumps. Thus, the problems are eliminated which always occur in the case of pumps, such as media incompatibility, suction problems or bubbles.

In addition, this results in a considerable cost saving, no costly balances and pumps are required. The flow is controlled by a solenoid valve. As no measurement and no regulation of the flow takes place, the dosing rate is not constant. However, in some cases, such as for the pH value control, the maintenance of a certain dosing rate is not so important. Here AlfaDos™ is the absolutely most inexpensive solution.


Gravimetric Dosing GraviDos®

Like a traditional dropping funnel, the innovative GraviDos® dosing system is simply driven by gravity and does consequently not require any pumps. Thus, the problems are eliminated which always occur in the case of pumps, such as media incompatibility, suction problems, bubbles, etc. The integrated weighing system takes up so little space that several dose loops can be comfortably integrated into one compact laboratory plant.

In addition, this results in a considerable cost saving, as no costl balances and pumps are required. The price advantage particularly comes to bear when several dose loops are required.
