LED Indicator

The LED indicator displays instrument status or behavior.

White to GreenThe system is running protocol.
Yellow (Blinking)Paused during a protocol execution.
RedAn error has occurred or the system detects a failure.
MulticolorThe system is idle.

Power Button

The various colors of the power button indicate the following status and behavior.

Red (Blinking)µPULSE is starting on or turned off.

Touch Screen

The touch screen controls the µPulse software.


Chip Cover

The chip cover securely holds the chip in place.


Rotating Release Lever

Rotate the lever from left to right to open the chip cover.


Filter Chip

µPULSE filter chips come with various membrane cutoff sizes: 5, 10, 30, 50, 100, and 300 kDa. See also, Hardware V2.

Note: Filter chips can be purchased from the FORMULATRIX online store at


Permeate Collector

The permeate collector transfers waste liquids from the chip to the permeate bottle.


Permeate Bottle Door

The permeate bottle door keeps the permeate bottle covered. You can easily check the bottle capacity through the window in the permeate bottle door.


Permeate Bottle

The instrument accepts both 50 mL conical tubes (using the supplied tube stands) or a 125 mL bottle.


Transfer Tubing

The transfer tubing connects to the chip for aspirating and returning the sample and/or buffer to the 50 mL tubes. It can be single-use or cleaned for reuse. See Chip Maintenance for more information.


Sample and Buffer Tube Positions

The left input of the µPULSE is for your sample. The right input can be used for additional sample or buffer. The system is compatible with all common varieties of 50 mL conical tubes.


Balance Pad

The balance pad provides a repeatable place for the tube adapter to sit. It detects and calculates volume changes when the µPULSE is running profiles.

Ethernet Port

The Ethernet port is used to connect the µPULSE instrument to the Internet through hard-wire.


Universal Serial Bus (USB) Port

The USB port is used for updating the µPULSE software manually if an Internet connection is not available. It may also be used by support for debugging or troubleshooting purposes.


Power Button

The power button turns the µPULSE On or Off. To turn off the device, it is preferred to shut down the system by tapping the SHUTDOWN button on the Home Screen. Then, press the power button.


Power Port

The power port is where you plug in the power cable. See also, Electrical Requirements.
