The MP36R Research System from BIOPAC Systems, Inc. is a highly flexible and powerful system for life science research and teaching. The four-channel MP36R Research System is a data acquisition system with built-in universal amplifiers that can record a wide range of physiological signals (e.g. EMG, ECG, EDA, Pulse Plethysmography, Respiratory Effort, Temperature, Air flow and many more). Start with one of our Starter Systems, then add compatible SS#L Series Lead SetTransducersStimulation, and Gas Analysis hardware to match your research design.


System components

All MP36R starter systems include the following items:

  • MP36R data acquisition unit
  • Latest AcqKnowledge software
  • USB cable and power supply
  • Digital guides and manuals


BIOPAC's MP36R Packages 

MP36R Scripting Package

The BIOPAC scripting package (-BAS) ships with an MP36R Data Acquisition unit and AcqKnowledge software licensed for BIOPAC Basic Scripting, a scripting language development option. Use BIOPAC Basic Scripting to customize the AcqKnowledge display…control, automate, or consoidate AcqKnowledge functions…and increase standardization and consistency to improve the quality of data. Scripting allows for viewing of runtime variables, creating new script files and editing existing script files, triggering of individual script functions for testing and single step functionalities. Scripts are easily created within AcqKnowledgeand do not require programming experience, but a familiarity with scripting will certainly help. Commands are documented in the online reference library and Script examples and tutorials assist in the learning and development process. The scripting license is available for AcqKnowledge4.1 and above.


MP36R NTD Package (Network Data Transfer)

BIOPAC's Network Data Transfer system (-NDT) includes an MP36R Data Acquisition unit and AcqKnowledge software licensed for Network Data Transfer, a real-time network data transfer system. Network Data Transfer allows access to the data being acquired into a graph by AcqKnowledge for use in an external application; the computer used to run the AcqKnowledge process and the custom application may be the same computer. NDT is a basic method for allowing third party applications to tap into the data stream being generated by both the MP unit and AcqKnowledge during data acquisitions.

  • NDT provides networking facilities that allow for integration into a distributed application environment.
  • NDT provides basic control facilities to allow external applications to query and control the AcqKnowledge application state.


MP36R Developer Package (Enterprise, Windows only)

The fully packed Enterprise (-ENT) Developer’s system from BIOPAC comes with an MP36R Data Acquisition unit and AcqKnowledge licensed for BIOPAC Basic Scripting and Network Data Transfer, plus BHAPI and ACKAPI hardware and software API for software development. 


AcqKnowledge Acquisition & Analysis Software

AcqKnowledge is an interactive, intuitive program that lets you instantly view, measure, analyze, and transform data. Perform complex data acquisition, stimulation, triggering and automated analysis routines using simple pull-down menus and dialogs - no need to learn a programming language or new protocol.
