Used VARIAN VHS 250 #293764955 for sale

VARIAN VHS-250 is a precision diaphragm pump designed for low flow-rate, low-pressure applications such as liquid sampling, liquid and gas chromatography, and sample introduction. The VHS series features low pulsation, high accuracy and high reliability in a compact, cost-effective design. VHS-250 is a precision diaphragm pump with a maximum flow rate of 250 ml/min. Its low flow capabilities make it ideal for applications that require high accuracy and precision such as liquid sampling, liquid and gas chromatography, and sample introduction. The pump is designed with a simple, efficient diaphragm design and the pump-head can be configured in either a tubing-style or manifold-style configuration. The tubing is designed to ensure minimal loss of the sample, while providing a flexible system that can be tailored to meet a wide variety of requirements and applications. VARIAN VHS-250 is capable of pressures up to 50 psig, providing flexibility for a variety of applications. The pump speed is adjustable over a wide range and can be set precisely via a digital speed controller. The speed and pressure are adjustable within the range of 1-250 ml/min. VHS-250 is equipped with various safety features. It has an overpressure valve to prevent damage to samples if the pressure exceeds safe limits. There is also an automatic feed stop that prevents over-pressurising the pump when the flow rate exceeds the preset limit. VARIAN VHS-250 has a simple design and low power consumption, allowing for efficient operation and high energy efficiency. The pump head contains an integral pumping system and control elements for easy installation and maintenance. The control knob is also conveniently located on the pump body, allowing operators to set flow rate without the need to open the pump. Overall, VHS-250 is an ideal choice for low-pressure applications such as chromatography and sample introduction. It is designed to provide a reliable, precise, and cost-efficient solution for liquids sampling and handling. VARIAN VHS-250 is a versatile pump with low pulsation and high accuracy. Additionally, its low power consumption and simple design make it an excellent choice for laboratories in need of an efficient and reliable pump.
