Higher Force Pump for Demanding Applications

The new KDS 410 is a high pressure syringe pump which more then doubles the linear force available on the KDS 200 series. This extra force makes the pump ideal for delivery of fluid to reactors in chemical applications or for working with viscous fluids. The robust design of the syringe holder ensures the syringe is kept level during delivery of the fluid. It features two different types of clamping mechanisms, for both smaller and larger syringes. When the application demands a more rugged pump, select the KDS 410. The KDS 410 features two modes of operation a dispense and a withdrawal mode. It is easy to set up and use in 2 quick steps; select the type of syringe and the flow rate. The selectable flow rate is entered directly into the program and stored in memory. A volume can also be set to dispense a known amount and then shut off.

Programmable pumps

All 200 series syringe pumps are available as programmable pumps, as well as the KDS 410 syringe pump.  They permit multistep dispenses without the need for computer control.

From the pump keypad, a custom program can be entered which will control the syringe pump from seconds to days; permit the flowrate to be changed for discrete time periods; repeat dispenses control output TTL signals to coordinate with other laboratory instruments (or valves); or respond to inputs from other devices such as switches or relays and to perform loops where dispense sequences are repeated.

The program is divided into time periods called STEPS, each of which can be up to 12 hours long.  Each step is automatically numbered and, to simplify programming, a menu prompts the user to select the options available in each step.

The flowrate can be ramped up or down or kept constant for a defined time period for a volume dispense.  The initial and final flow rate for each period is entered and the pump automatically makes rate changes over the time period.  No need to enter increments for a ramp up or down, the syringe pump automatically ramps the rate linearly.

The syringe pump can be paused and then restarted, either by a time delay or by a TTL input.  Both TTL inputs and outputs can be controlled by the pump.   The syring pump can therefore, respond to switch closures or send out signals to actuate a valve, or other relays, switches etc.

Two separate loops can be programmed so that steps can be repeated.  The number of repeat operations is controlled by the "loop count".  For example, this is helpful when a volume dispense is required repeatedly, triggered by a switch.

The two loops can be "nested" so that the program can run for days and complex dispenses can be repeated many times.

Each step offers these options:

1. Time duration from one second up to 12 hours
2. Travel direction – Infuse or withdraw (where available)
3. Beginning flow rate (µl/hr to ml/min range)
4. End flow rate (µl/hr to ml/min range)
5. Pause – Waits for an external trigger to start
6. Status of output TTL pins
7. Loop option – Loops back to any previous step and repeats the intermediate steps.  Two separate loops are available.
8. Set the count in the loop cycle.  Steps may be repeated up to 100 times.
