OB1 MK3+pressure vacuum controller

Product features:
OB1 MK3+is a high-performance multi-channel microfluidic pressure and flow controller. The number of pressure output channels can be customized from 1 channel to 4 channels, and 5 pressure ranges can be mixed and customized for use. The OB1 controller has the characteristics of modularity, upgradability, and inclusion of graphical operating software.

• Pressure stability -0.005% of full range

• Response time ---9 ms

• Pressure resolution -0.006% of full scale

• Establish/stabilize time -35 ms

  ‍

• Number of pressure channels: up to 256 pressure channels, default OB1 MK3+pressure flow controller channel number can be selected from 1 to 4;

• Characteristics between pressure channels: Each pressure channel is independent of each other and can independently control pressure output. At the same time, through ESI software, multiple pressure channels can also be coupled together to form a linkage work;

  ‍

• Pressure channel range: Provides five pressure range options, namely 0-200 mbar, 0-2000 mbar, 0-8000 mbar- 900 mbar~1000 mbar and -900 mbar~6000 mbar. These 5 pressure channel ranges can be mixed and integrated into the same OB1 MK3+pressure flow control, for example, channel 1 ranges from 0 to 200 mbar, channel 2 ranges from 0 to 2000 mbar, channel 3 ranges from -900 mbar to 1000 mbar, and channel 4 ranges from -900 mbar to 6000 mbar;

• Number and range of channels can be upgraded: In the future, the number and range of pressure channels can be upgraded based on existing equipment. For example, if you already have an OB1 MK3+pressure flow controller with 2 channels ranging from 0 to 2000 mbar, you can continue to upgrade one pressure channel with a range of -900 mbar to 1000 mbar. After the upgrade is completed, it will not have any impact on the performance of the existing pressure channel.

• Flow sensor connection: The high-precision digital flow sensor MFS is directly connected to the OB1 MK3+pressure flow controller without the need for third-party adapters;

• Accurate measurement and constant flow control of multiple microfluidics: The Coriolis flow sensor BFS is a mass flow sensor that can directly measure the mass flow rate, volume flow rate, density, and temperature of liquids. The liquid medium can be a single liquid or a mixed liquid. More importantly, when measuring each liquid medium, there is no need to calibrate the liquid medium separately, with a measurement accuracy of up to 0.2% of the measured value. Connect the USB cable directly to the computer without the need for a third-party adapter. In addition, BFS flow sensors can also measure the mass flow rate, volume flow rate, density, and temperature of gases. When used in conjunction with the OB1 MK3+pressure flow controller, it can achieve closed-loop constant current control function.

• Constant flow control (constant flow function): Fast response and stable closed-loop fluid flow control can achieve high-precision microfluidic flow injection and smooth fluid flow without pulsation.

• Diversity waveform control: Free ESI operation software directly provides pressure output control for sine, square, triangular, ramp, and custom waveforms, as well as flow control for microfluidics, without any programming operation;

• Experimental system flow resistance diagnosis function: The free ESI operation software provides flow resistance diagnosis function for microfluidic experimental systems, which can provide flow resistance optimization suggestions for specific microfluidic experimental device systems, greatly improving the fast stability and responsiveness of fluid control, as well as precise quantitative injection of micro upgraded liquid volume.

• Pressure sensor connection: The MPS pressure sensor can be directly connected to the OB1 MK3+pressure flow controller without the need for a third-party adapter. The pressure sensor MPS can measure fluid pressure fluctuations in real-time in pipelines or achieve constant pressure control of liquids at designated locations in pipelines.
