Channel #1 = 0/2000 mbar | Channel #2 = -900/1000 mbar | Channel #3 = -900/1000 mbar. Upgradable : possibility to add 1 independent channel of any pressure range to this OB1. All necessary fittings & tubing are available in the Kit Fitting OB1 Starter Pack Push-in. Includes one Microfluidic Air Flow Cleaner Kit (5 µm pore size pneumatic filter). Elveflow® Smart Interface software included. Important note: additional pressure (6.5-10 bar) & vacuum sources are required. Cutting-edge Microfluidic Flow Controller Designed by scientists for scientists, the versatile and powerful OB1 MK4 pressure controller provides the perfect flow control for all kinds of applications.Whether you need pressure or vacuum, low or high flow rate, for short or week-long processes and experiments, the OB1 MK4 is the ideal instrument for your microfluidic needs. The Best Performance in the Market: Piezoelectric Technology The Elveflow OB1 MK4 is the only microfluidic flow control instrument worldwide to use piezoelectric regulators. The piezoelectric technology gives you 20 times more precise and 10 times faster flow control than any other flow controller on the market. Customizable & Upgradable: 1 Module, Up to 4 Channels, 5 Pressure & Vacuum Ranges Available The OB1 MK4 can be configured according to your needs. In one piece of equipment, you can have up to 4 pressure and/or vacuum channels (and other customized options). If your needs change, the instrument can be upgraded later, in any way you want. Get the Fastest Flow Rate Control When Paired with a Flow Sensor Connect the OB1 MK4 to a standard liquid flow rate sensor (MFS) or our premium Coriolis flow sensor (BFS, suited to both liquid and gas) to directly control the flow rate in your chip. The system continuously calculates the pressure and maintains the desired and constant flow rate. Full Control Software, SDK, and UART Communication Single and intuitive software to get started in a few clicks and automate the most complex and long experiments. The SDK libraries allow you to control the OB1 MK4 using your own code while connecting it to other instruments. The MK4 is also equipped with UART communication protocol in addition to the ESI and SDKs control, allowing it to communicate with most control systems, such as Mac, Linux, Arduino, PLC. OEM Version Available The OB1 MK4 can be used on a bench setup or embedded in your own product. Elveflow has a solution for every step of your research & development.
