LAMBDA POWDER DOSER

for powder dosing. Unique powder pump for free-flowing solid substances.

• For automatic or continuous addition of solids, powders, crystalline substances, nano-materials and nano powders without a spoon.
• Dosing speed range from 0 to 999.
• Reproducible dosing flow rates (e.g. 50 mg/min to 50 g/min for NaCl).
• Allows operation in controlled atmospheres.
• Safe operation with hazardous material - GLP.
• Programmable; Remote controls; RS-interface
• Easy assembly and cleaning

he LAMBDA DOSER powder feeder is a unique programmable powder pump for free-flowing solid substances. It allows the automatic or continuous addition of powders, powdery and crystalline substances without a spoon.

This laboratory instrument, consisting of a dosing unit coupled to a digitally controlled stepping motor, allows the constant and reproducible dosing of solids. As the DOSER powder feeder offers different control options, it can also be used in automatically controlled processes.

The LAMBDA DOSER solid feeder / powder pump will modernize your laboratory.
Properties of the LAMBDA DOSER powder dosing instrument
Dosing rate

The digital dosing speed range from 0–999 allows a precise and reproducible solid flow rate (e.g. 50 mg/min to 50 g/min for NaCl).
Programmable

27 pairs of dosing speeds and dosing times can be easily programmed.

Safety
With the DOSER the additions of powdery chemicals become reproducible, safe and conform to modern safety and quality rules (GLP), as it is required for the laboratory manipulation of chemicals. The hermetic construction of the DOSER allows safe handling of dangerous and toxic solid substances.

Assembly and cleaning
The dosing apparatus has been constructed for easy assembly and cleaning. The DOSER can be coupled to all common glass recipients having standard ground fittings NS 29/32 or SVL threaded connectors. All parts in contact with the powdery substances are made of chemically resistant materials.

Small dimensions and robust construction
Special attention has been paid to minimizing the dimensions of all parts of the powder DOSER. The DOSER can be adapted easily to complex laboratory installations. The robust construction and the use of high quality materials assure a long lifetime of the DOSER.

Controlled atmosphere
Several seals make the DOSER air-tight and it can be used with a slight over- or under-pressure. The glass vessel can also be flushed by a neutral gas, if it is necessary for a given reaction.

Economical
Automatic dosage frees technicians for other works. Due to better reproducibility and elimination of errors the number of experiments can be reduced. The DOSER offers an excellent price-performance ratio.

Remote controls
The speed of addition can be remotely controlled over the whole range by applying a voltage of 0 to 10 V and switch-ON/OFF is controlled through an external contact or 12 V signal. The RS-485 or RS-232 interface (optional) allows for enhanced PC control (variable flow rates, dosing gradients, etc.). A PC control software PNet is also available (optional).

Quantification of the dosed substances
The powder DOSER can be configured with the electronic LAMBDA INTEGRATOR (optional) and allows the quantification of the amount of powder added as a function of time. This provides important information on the processes or reactions, e.g. when the DOSER is controlled by a controller (pH-stat, thermostat, etc.)
