Used GL SCIENCES GL-7420 #9165848 for sale

GL SCIENCES GL-7420 is a lab equipment and accessory designed for use in precision laboratories. It is a highly precise and reliable inert gas flow controller capable of providing accurate and predictable gaseous flow over a wide range of flow rates. Its robust and compact design makes it suitable for use in diverse applications, such as chromatographs, ion implanters, and surface chemistry reactors. GL-7420 is based on a single-pressure control system and offers excellent accuracy, sensitivity, and repeatability. The device features a digital proportional-integral-derivative (PID) controller, which accurately responds to the changes in flow rates, making the gas flow moreconsistent. This ensures a uniform flow rate even when there is a discrepancy between setpoints. GL SCIENCES GL-7420 also offers precise adjustment capabilities, allowing the user to fine-tune the flow rate for each application. GL-7420 is equipped with a stainless steel mass flow sensor, which provides precise measurements of gas flow rates over a wide range. This sensor is highly responsive, making the adjustments needed to maintain the desired output of the unit very simple. GL SCIENCES GL-7420 is also equipped with four gas registers, which allow the user to easily adjust the actual gas output to match the desired flow rate. Furthermore, the device also includes an integrated pressure gauge that displays the actual gas pressure. This provides the user with a quick indication of the pressure and enables them to adjust the pressure in order to achieve the desired output of the unit. GL-7420 provides a number of safety features. It is equipped with an isolation valve to protect against gas leaks, as well as a back pressure valve that prevents excess pressure. Additionally, the unit has an emergency stop button and integrated alarm system for easy monitoring and safety in emergency situations. Overall, GL SCIENCES GL-7420 is an excellent choice for precision laboratories that require reliable inert gas flow controllers. Its accuracy, repeatability, and ease of adjustment make it a versatile and dependable tool for a wide range of laboratory applications.
