Scientific & Industrial Dispensing Pumps & Metering Pumps SV690 Stepper Motor Driven Syringe Pump


The SV690 series syringe pump module is a direct-drive stepper motor-driven pump that accurately and precisely delivers a wide range of liquids. With dispensing ranges from a few microliters to 12.5 milliliters, the SV690C utilizes standard communication protocols and mounting configurations used by other compact syringe pump designs. The SV690C is perfectly suited for analytical and medical applications where precision dispensing of reagents, buffers, diluents, and gradients are critical to the performance of the instrument. The SV690 is also well suited for single-point aspiration and dispense of samples.


The SV690 series is a versatile pump module that provides all typical aspiration and dispensing operations expected from an OEM syringe pump. The SV690C is also ideal for the researcher looking for a complete desktop syringe pump system that can be set up and running in less than 15 minutes. Fully interchangeable syringes provide for a wide range of dispensing volumes with minimal investment.
