You can pay using your credit card via PayPal. Most importantly, it is not necessary to have a PayPal account to make the payment via credit card.
The biggest particle size for powders that could be dosed with our DOSER is about 4 mm. A good dosing of powders depends essentially on the flowing properties of the respective powders to be dosed. In general, homogeneous and free-flowing powders can be dosed best.
The powder / granules / solid must be properly treated for good flowing properties It is also possible to allow a gas flow to pass through the Lambda dosing vessel in order to create a controlled atmosphere.It is often possible to substantially improve the flowing properties of the respective powder / granules / solid by adding Aerosil (fumed silica – pure SiO2) to your powder (~0.1 - 2% by weight).
In the case of abrasive materials being used with the LAMBDA Powder DOSER, you will have an opportunity to replace the glass vessel and / or the distributors as needed.
The motor of the driving unit is controlled with quartz-driven electronics, similarly as it is done in electronic watches.Therefore, the accuracy depends mainly on the powder. For best accuracy and precise doses, the powder needs to be free-flowing and homogeneous.
It is always possible to control the mass flow rate of the powder using the LAMBDA Doser. You could program the DOSER up to 27 pairs of speed and time settings to control your desired mass flow rate (g/min).
Yes, the powder DOSER can be controlled by Mettler Titration Excellence T50/T70/T90 via RS-232 communication (most common type of connection with Mettler accessories), to dispense the desired amount of powder to the titration process. The powder DOSER has to be included as RS-232 control in the titroprocessor unit and the desired activity can be selected (e.g.: the signal would switch off the DOSER or switch it on, etc.) For integration of DOSER with your Mettler titroprocessor, you would need the RS-232 interface activated in the powder dosing unit and RS-232 connection cable.
