Used VARIAN TV 401/301 #9286937 for sale

VARIAN TV 401/301 pump is a versatile and reliable pumping equipment with a range of features to maximize chemical analysis accuracy and efficiency. VARIAN TV 401/301 pump is primarily used for gas and liquid chromatography. It has a flow control range of 0.1 to 400 mL/min, depending on the back pressure range of 0.05 to 7 bar (1 bar = 1 atmosphere). This pump has a pressure control accuracy of 0.1%. The inlet and outlet pressure gauges make it easy to control the pressure in the system. VARIAN TV 401/301 pump includes circulation and eductor loops along with a simple to use two-stage charging process. During operation, the circulation loop pressurises the eductor loop to move sample from the inlet to the analysis channel. The analysis chamber pressurises the semi-circular rotor and moves liquid sample from the inlet to the sample injection port. The sample is then moved to the retention column for analysis. The sample introduction process can be adjusted with a knob to ensure consistent and accurate results. VARIAN TV 401/301 pump is equipped with several programming features as well. The display panel is easily navigable and provides the user with complete information about the pump's operation. The built-in microprocessor and main processor make programming and communication adaptable to the user's needs and preferences. With the QuickConnect software, users can connect the pump to a computer to monitor the operation of the unit in real time. VARIAN TV 401/301 pump is equipped with an automatic leak detect machine that is user adjustable and will detect when exceeding the set pressure of the pump. In addition, the failure alarm will alert the user if there is any error or malfunction. The alarm tool can be customized to maximize asset security and to avoid errors. This pump provides a high-pressure analysis model that is reliable and accurate. With its wide range of features and its compatibility with various chromatography systems, VARIAN TV 401/301 pump is an important tool for efficient and reliable chromatography.
