For safe dosing of chemicals in your lab. Unique powder pump for free-flowing solid substances.<\/p>\n<\/div>\n<\/div>\n

\n
\n

The LAMBDA DOSER & HI-DOSER powder feeder is a\u00a0unique programmable powder pump for free-flowing solid substances<\/strong>.<\/p>\n

It allows\u00a0automated\u00a0continuous\u00a0dispensing or intermittent addition\u00a0(with pauses)\u00a0<\/em><\/strong>of powders, powdery and crystalline substances without a spoon.<\/p>\n

The powder dispensers with an optional\u00a0foot-switch<\/strong>\u00a0can be\u00a0used to\u00a0dispense the powder in portions\u00a0in media preparation, monitoring and screening.<\/p>\n

LAMBDA DOSER \/ HI-DOSER powder feeder will modernize your laboratory<\/h2>\n

The powder dispenser\u00a0consisting of a dosing unit coupled to a digitally controlled stepping motor, allows the constant and reproducible dosing of solids.<\/p>\n

As the DOSER \/ HI-DOSER powder feeder offers different control options, it can also be used in automatically controlled processes.<\/p>\n

Automation of the powder dispensing process<\/strong>\u00a0in the life sciences, pharmaceutical or analytical laboratory can be done with the programmable powder dosing pump as it\u00a0reduces human error, risk of spillage and conforms to laboratory safety standards.<\/strong><\/p>\n

Properties of LAMBDA DOSER \/ HI-DOSER powder dosing instrument<\/strong><\/h2>\n

Dosing\u00a0rate\u00a0of powder dispenser<\/strong><\/h3>\n

The dosing speed can be set directly on the control display of the powder feeder\u00a0or remotely\u00a0from 0\u2013999 speed range for precise and reproducible solid flow rate.<\/p>\n

The powder dosing rate depends mainly on the powder properties.<\/p>\n

For example, the\u00a0dosing rate\u00a0range of NaCl<\/strong>\u00a0at our laboratory conditions:<\/p>\n

    \n
  • LAMBDA DOSER:\u00a050 mg\/min to 50 g\/min<\/strong><\/li>\n
  • LAMBDA HI-DOSER,\u00a0slow mode*<\/em>: 60 mg\/min to 60 g\/min<\/li>\n
  • LAMBDA HI-DOSER,\u00a0fast mode*<\/em>:\u00a0250 mg\/min to 250 g\/min<\/strong><\/li>\n<\/ul>\n

    *On the HI-DOSER unit, you can work with either slow or fast mode at a time, based on your flow rate requirement.<\/em><\/p>\n

     <\/p>\n

    Program dosing\u00a0speed, time and pauses<\/strong><\/h3>\n

    Dosing speeds and dosing times with pauses can be easily\u00a0programmed locally on the pump display<\/strong>.<\/p>\n

    The entered program can be repeated ‘n’ number of times\u00a0(1-99 or infinite loop)<\/em>\u00a0with the \u201ccycle\u201d setting in the program.<\/p>\n

    Volume of storage vessels<\/strong><\/h3>\n

    DOSER and HI-DOSER powder feeders are supplied with the following glass vessels:<\/p>\n

      \n
    • Approx.\u00a0200 ml or 0.2 L<\/strong>\u00a0glass vessel
      \nCorresponds to 250 g NaCl, 200 g NaHCO3 or 150 g sucrose. This capacity is optimal for most laboratory applications.<\/li>\n
    • 1 L<\/strong>\u00a0glass vessel (approx. 1 L volume)<\/li>\n
    • 3 L<\/strong>\u00a0glass vessel (approx. 3 L volume)<\/li>\n<\/ul>\n

      The glass vessels are\u00a0interchangeable<\/strong>.<\/p>\n

      For\u00a0larger volumes<\/strong>, the side neck in the glass vessel allows filling during operation.<\/p>\n

      Remote control of powder pump<\/strong><\/h3>\n

      The\u00a0whole speed range<\/strong>\u00a0of powder dispensing can be remotely controlled by applying a voltage of\u00a00-10V<\/strong>.<\/p>\n

      Switching the powder feeder on and off (ON\/OFF<\/strong>) is controlled\u00a0by an external contact or\u00a012V signal<\/strong>.<\/p>\n

      The\u00a0RS-485 or RS-232 interface<\/strong>\u00a0(optional) allows for enhanced PC control (variable flow rates, dosing gradients, etc.).<\/p>\n

      A\u00a0PC control software PNet\u00a0is also available (optional).<\/p>\n

      Please refer the\u00a0LAMBDA DOSER \/ HI-DOSER User Manual\u00a0for connection details.<\/p>\n

      Data storage and visualization<\/strong><\/h3>\n

      The\u00a0PNet PC control software<\/strong>\u00a0is ideal for remote control of dosing units, data storage and visualization of powder dosing.<\/p>\n

      You can connect up to 6 powder dispensers via RS-485 interface and cables to USB or serial port of the computer, without having to purchase additional software licenses for the additional laboratory equipment.<\/p>\n

      The\u00a0PNet\u00a0software allows to create dosing\u00a0profile,\u00a0record data for analysis or comparison, visualize real time trends and save data to PC.<\/p>\n

      Conformity to safety in lab<\/strong><\/h3>\n

      The powder dispensers LAMBDA DOSER and LAMBDA HI-DOSER allows a safe and reproducible\u00a0dosing of hazardous\u00a0chemicals in the lab and conforms to modern safety rules.\u00a0To protect the laboratory technician or researcher or student, the powder dosing device can also be controlled remotely.<\/p>\n

      The hermetic construction of the DOSER and HI-DOSER allows\u00a0safe handling of dangerous and toxic solid substances<\/strong>.<\/p>\n

      Several seals make the DOSER air-tight and it can be used with a\u00a0slight over- or under-pressure<\/strong>.<\/p>\n

      If the\u00a0powder sample has to be\u00a0protected from agglomeration or reaction with air humidity<\/strong>, the glass vessel can be\u00a0purged with inert gas or dry air<\/strong>\u00a0using the supplied gassing plug.<\/p>\n

      If the\u00a0process needs to be protected from the risk of breakage, you can also order the\u00a0glass\u00a0vessels with a silicone coating<\/strong>\u00a0(outside)<\/em>.<\/p>\n

      All parts in contact with the powdery substances are made of\u00a0chemically resistant materials<\/strong>.<\/p>\n

      Quality standards\u00a0for powder dosing<\/strong><\/h3>\n

      LAMBDA DOSER \/ HI-DOSER powder feeders are recommended for high quality standard of powder dosing in the laboratory.<\/p>\n

      In addition to the\u00a0digital setting\u00a0and\u00a0precise dosing mechanism<\/strong>, the\u00a0automatic recording of dosing data\u00a0makes it an optimal choice to dispense\u00a0powders under GMP and GLP.<\/p>\n

      Simple and easy to use lab device<\/strong><\/h3>\n

      The lab powder dispensers DOSER and HI-DOSER has been\u00a0designed specially for\u00a0easy assembly and cleaning<\/strong>. The laboratory powder feeder, is thus, quickly\u00a0out to together\u00a0to use:<\/p>\n

      Fixing\u00a0to lab equipment: By standard glass adapters<\/strong><\/h4>\n

      The DOSER and HI-DOSER can be\u00a0coupled to all common glass recipients<\/strong>\u00a0having standard ground fittings\u00a0NS 29\/32<\/strong>\u00a0or SVL threaded connectors. It can also be\u00a0fitted to the reactor vessel<\/strong>\u00a0using an adaptor.<\/p>\n

      Special attention has been paid to\u00a0minimizing the dimensions<\/strong>\u00a0of all parts of the powder dispenser. Thus, DOSER 0.2 L can be\u00a0adapted easily to complex laboratory installations<\/strong>.<\/p>\n

      The robust construction and the use of high quality materials assure a long lifetime of the powder feeders.<\/p>\n

      Economic powder dosing<\/strong><\/h3>\n

      Automated dispensing of same amount of repeated powder addition in the lab gives the time for the lab staff to work on other tasks.<\/p>\n

      Due to\u00a0better reproducibility<\/strong>\u00a0and\u00a0elimination of errors,<\/strong>\u00a0the number of experiments can be reduced.<\/p>\n

      The DOSER and HI-DOSER offers an\u00a0excellent price-performance ratio<\/strong>.<\/p>\n

      Quantification of the dosed substances<\/strong><\/h3>\n

      The powder DOSER can be configured with the electronic\u00a0LAMBDA INTEGRATOR\u00a0(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.).<\/p>\n<\/div>\n<\/div>\n
