KD Scientific Multi Syringe Infusion Pump KDS220

KD Scientific KDS220 Multi-Syringe High-Capacity Infusion Pump (78-0220V)

The KD Scientific KDS220 Multi-Syringe Infusion Pump (78-0220V) is a high-precision, microprocessor-controlled laboratory syringe pump designed for applications requiring simultaneous, smooth fluid delivery across multiple channels. Engineered to hold up to 10 syringes simultaneously, this dual-guide rod rack assembly provides rigid mechanical stability and pulseless linear flow across micro-dosing and high-volume infusion protocols. Driven by a high-step-resolution stepper motor and precision lead screw, the KDS220 delivers accurate, reproducible flow rates from 0.001 microliters per hour up to 140 milliliters per minute depending on the installed syringe geometry. Featuring a back-lit digital display with a simple keypad interface, the system allows operators to enter exact syringe inner diameters, volume targets, and flow rates. Equipped with an RS-232 serial interface for automated computer control, the KDS220 is an essential tool for microfluidics, electrospinning, continuous chemical synthesis, and multi-channel animal infusions.

Technical Performance & Structural Attributes

• High-Capacity Multi-Syringe Rack: Adjustable syringe rack accommodates up to 10 syringes (10 microliters to 10 milliliters) or up to 6 syringes (20 milliliters to 140 milliliters) for simultaneous parallel dosing.
• Precision Linear Lead Screw Drive: Micro-stepping drive motor paired with heavy-duty dual guide rods eliminates pulsing and mechanical backlash during low-flow micro-dosing.
• Programmable Microprocessor Control: Intuitive non-volatile memory stores user-set parameters, including syringe inner diameter, flow rate unit selection, and total target volume cutoff.
• Rugged Industrial Enclosure: Heavy-gauge steel housing shields internal mechanical components and power electronics from chemical spills and mechanical wear on laboratory benches.
• RS-232 Serial Communication Port: Enables remote computer control, automated parameter programming, and multi-pump daisy-chaining via TTL or serial commands.
