Polyvalent programmable syringe pump – LAMBDA VIT-FIT<\/h2>\n

These days there are so many different types of syringes and so many different volumes used\u2026<\/p>\n

Some users need a standard syringe from a certain producer; others use only glass, metal or plastic syringes. Volumes start from few microlitres to over 150 millilitres.<\/p>\n

Is it possible to satisfy everybody with just a single syringe pump?<\/strong><\/p>\n

With our new VIT-FIT syringe pump we have tried to solve just this problem.<\/p>\n

Our new syringe fixing system allows\u00a0almost any syringe to be used<\/strong>, from micro syringes to large volume syringes,\u00a0without the use of an adapter<\/strong>. The syringe is tightly held in both directions \u2013 infusion and filling.<\/p>\n

In addition, the handling of the syringes is very easy.<\/p>\n

 <\/p>\n

Construction advantages and properties of the VIT-FIT (HP) syringe pumps<\/h2>\n

\"Construction<\/a><\/p>\n

Precision mechanics for pulse-free operation<\/h3>\n

To move the pusher of the VIT-FIT syringe pumps and the VIT-FIT HP high-pressure syringe pumps, we have selected a\u00a0Swiss made motor<\/strong>\u00a0which uses new technology to ensure\u00a0very high torque and ten times longer lifetime<\/strong>.<\/p>\n

For the transformation of the rotation into a linear movement required for pushing the syringe plunger, we have introduced the\u00a0Swiss made ball screws with highest mechanical load capacity<\/strong>. This is an expensive component in our instrument, but it offers decisive advantages to the user in terms of efficiency and mechanical yield\/force of the system. This is crucial for a\u00a0pulsation-free operation<\/strong>.<\/p>\n

 <\/p>\n

Metal chassis and\u00a0protection<\/h3>\n

The\u00a0precise mechanics is protected<\/strong>\u00a0in the instrument casing and the\u00a0pusher arm does not reach out from one side<\/strong>\u00a0(as it is usual with existing syringe pumps), but is integrated into the rear of the instrument.<\/p>\n

The casing and the main body of the syringe pump are made of metal with\u00a0solvent resistant protection<\/strong>.<\/p>\n

 <\/p>\n

Programming flow\u00a0profile (infusion and filling)<\/h3>\n

The microprocessor electronics allow control of the activity of the syringe pump in an easy but effective way. The movement of the new brushless neodymium magnet motor is constantly under the control of the microprocessor, which corrects immediately any deviation from the preset speed.<\/p>\n

Up to\u00a099 program steps<\/strong>\u00a0can be memorized by the processor. The syringe pump can be programmed in both directions – delivery (infusion) and filling, locally on the syringe pump control display.<\/p>\n

The program can be\u00a0repeated<\/strong>\u00a0in\u00a01 to 99 cycles or endlessly<\/strong>.<\/p>\n

    \n
  • Constant flow rate:<\/strong>\u00a0In this standard application of the syringe pump \u2013 the flow rate will be kept constant during the pre-selected time period<\/li>\n
  • Profile:<\/strong>\u00a0Permits varying flow rates to be pre-programmed (including exponentially increasing flow rate as used for e.g. in feeding cultures during fermentation, etc.)<\/li>\n
  • Increment:<\/strong>\u00a0Stepwise increase of the flow rate over time (to make gradients)<\/li>\n
  • Decrement:<\/strong>\u00a0Stepwise decrease of the flow rate<\/li>\n
  • Pause:<\/strong>\u00a0Stops the syringe pump for a specified time before going on to the next step<\/li>\n
  • Timer:<\/strong>\u00a0By programming a required time interval with zero flow rate as the first step before the program the syringe pump can be automatically switched on or off<\/li>\n
  • Stop:<\/strong>\u00a0Stops the syringe pump after the program has finished.<\/li>\n<\/ul>\n

    Safe switching power supply<\/strong><\/h4>\n

    As the mechanical losses are so small, we can use a miniature plug-integrated switching power supply using line voltages (from 95 to 240 V AC, 50\/60 Hz).<\/p>\n

    During\u00a0field application<\/strong>\u00a0the syringe pump can be powered by a 12 V accumulator or a 12 V battery.<\/p>\n

    Automatic switch\u00a0OFF<\/strong><\/h4>\n

    The motor of the syringe pump will be\u00a0switched off automatically<\/strong>\u00a0when the\u00a0syringe is empty<\/strong>\u00a0or has been\u00a0refilled<\/strong>.<\/p>\n

    Remote control (analog and digital)<\/strong><\/h4>\n

    Several remote control possibilities of the syringe pump are available:<\/p>\n

      \n
    • Simple\u00a0ON\/OFF<\/strong>\u00a0(with a 3 to 12 V DC signal or higher with resistor)<\/li>\n
    • Progressive<\/strong>\u00a0speed control over the\u00a0whole range signal<\/strong>\u00a00 to 10 V DC, (0 to 20 or 4 to 20 mA option)<\/li>\n
    • RS-485 or RS-232 interface<\/strong>\u00a0(option) for communication with a PC or similar device<\/li>\n<\/ul>\n

      Speed selection \/ syringe calibration<\/strong><\/h4>\n

      To be able to fit the many types of syringes used, the speed selection is made using speed numbers corresponding to the velocity of the rotation of the motor.<\/p>\n

      The selected syringe has to be calibrated. This means that the\u00a0motor speed setting<\/strong>\u00a0(000 to 999)<\/em>\u00a0has to be put into relation with the\u00a0delivered volume as a function of time<\/strong>\u00a0(flow rate). The\u00a0flow rates<\/strong>\u00a0and delivered volumes corresponding to each speed setting are then easily calculated.<\/p>\n
