The MINIPULS 3 is a rugged peristaltic pump with interchangeable heads for delivering smooth, low pulse flows of biological and chemical fluids in 1, 2, 4, or 8 channel standard flow rate and 2 or 4 channel high flow rate configurations. Gilson's MINIPULS® 3 is a peristaltic pump specifically designed to meet process laboratory liquid handling needs. The MINIPULS 3 peristaltic pump combines microprocessor speed control with a high-torque stepper motor. Chemical-resistant pump heads, equipped with 10 stainless steel rollers, set the performance standard in producing smooth, low-pulse flow and reproducible flow rates at higher pressures.
