Pump Component

This component allows you to deliver liquid stimuli using a Cetoni neMESYS syringe pump.

Please specify the name of the pump configuration to use in the PsychoPy preferences under Hardware / Qmix pump configuration. See the readme file of the pyqmix project for details on how to set up your computer and create the configuration file.

Properties

Name : string
Everything in a PsychoPy experiment needs a unique name. The name should contain only letters, numbers and underscores (no punctuation marks or spaces).
Start :
The time that the stimulus should first appear.
Stop :
Governs the duration for which the stimulus is presented.
Pump index : int
The index of the pump: The first pump’s index is 0, the second pump’s index is 1, etc. You may insert the name of a variable here to adjust this value dynamically.
Syringe type : select the appropriate option
Currently, 25 mL and 50 mL glass syringes are supported. This setting ensures that the pump will operate at the correct flow rate.
Pump action : aspirate or dispense
Whether to fill (aspirate) or to empty (dispense) the syringe.
Flow rate : float
The flow rate in the selected flow rate units.
Flow rate unit : mL/s or mL/min
The unit in which the flow rate values are supplied.
Switch valve after dosing : bool
Whether to switch the valve osition after the pump operation has finished. This can be used to ensure a sharp(er) stimulus offset.
Sync to screen : bool
Whether to synchronize the pump operations (starting, stopping) to the screen refresh. This ensures better synchronization with visual stimuli.
