The setup of the powder dispensing system, LAMBDA DOSER is very easy - a short video of the installation is in this section
Figure 1-1: The ground glass piece is put through the threaded screw cap SVL 42. | Figure 1-2: The Teflon disc is put inside the screw cap and placed on the ground surface of piece. |
Figure 1-3: The screw cap with the Teflon disc and ground glass piece is screwed to the Doser glass vessel with one side arm. | Figure 1-4: The distributor (standard) is inserted inside the glass tube with its opening directed downwards so that it will not be damaged. |
Figure 1-5: There is a silicon baffle on the lowest part of the tube. The distributor must be turned with its opening towards this baffle. | Figure 1-6: Teflon treated rubber seal is placed on the centering part with the Teflon layer facing outside (towards the glass tube). |
Figure 1-7: Place the centering part with the rubber seal on the axis of the distributor. | Figure 1-8: Secure the centering part with through the axis of the distributor with the screw cap to the glass vessel. |
Figure 1-9: Axis of the motor unit with metal pins and the centering part with six holes. | Figure 1-10: Press the axis of the motor unit completely inside the centering part. So that the metal pin of the motor unit will fit into one of the six corresponding holes in the centering unit. This assures a perfect seal of the DOSER and a sufficient pressure of the distributor against the Teflon disc in the bottom of the Doser vessel. |
Figure 1-11: The 12 V connector of the power supply is plugged into the 12 V DC socket of the motor unit and the power supply is connected to the mains. | Figure 1-12: The solid is added through the filling arm of the tube. The filling arm can be closed with a ground glass or plastic stopper NS 29/32. |
