Manufacturer: Molecular Devices
Model: VersaMax

The VMax Kinetic ELISA Microplate Reader, the first of its kind for monitoring reactions over time, opened the door to enzyme assays and continues to be the workhorse of the laboratory environment. Based on a rugged simple design, the VMax Absorbance Microplate Reader offers a mean time between failure (MTBF) of 20,000 hours with 97 independent and stationary fiber optics so that the microplate remains stationary during the entire reading cycle, reducing the number of moving parts that can wear and need replacement. Through sequential, single-well illumination, 100% of the available light is directed to each well through the optical fibers to achieve linearity to higher optical densities (ODs) and optimal signal-to-noise ratios. At 5 seconds to read a 96-well endpoint assay or a 5 second minimum interval between kinetic reads, the VMax Microplate Reader has both speed and performance.

Plate Reader Commands

  • Close Document

    void closeDocument()Closes the current document. If the data has not been saved, the document is closed anyway without user warning.
  • Close Drawer

    void closeDrawer()Closes the instrument drawer.
  • Select All

    void selectAll()Selects all the data in the table for copying or exporting.
  • Export As

    void exportAs(string filePath)Exports data in the standard SoftMax Pro format to the specified file.

    Parameters:

    • filePathFile path for the exported file.
  • New Plate

    void newPlate()Creates a new plate section within the current experiment.
  • Open Assay

    void openAssay(string filePath)Opens a protocol file.

    Parameters:

    • filePathFile path for the protocol file. The file should be in SoftMax Pro Protocols folder if the full file path is not specified. Protocols can also be stored in subdirectories of the Assay folder. SoftMax Pro appends “.ppr” to any file name passed in.
  • Open Document

    void openDocument(string filePath)Opens a a new document (i.e. data file). The file should be in SoftMax Pro application folder unless the full file path is specified.

    Parameters:

    • filePathFile path for the document.
  • Read

    void read()Starts reading of the microplate.
  • Return Status

    string returnStatus()Returns the current instrument status. This command can be sent to check whether the instrument is busy or reading or staying idle.

    Returns:

    Current status of the instrument.
  • Set Port

    void setPort(int portNumber)Tells the SoftMax Pro to use the specified serial port.

    Parameters:

    • portNumberSerial port number.
  • Set Temperature

    void setTemp(float temperature)Sets the current instrument incubator temperature.

    Parameters:

    • temperatureInstrument incubator temperature.
  • Shake On

    void shakeOn()Starts shaking the microplate tray.
  • Shake Off

    void shakeOff()Stops shaking the microplate tray.
  • TrayLock On

    void trayLockOn()Keeps the microplate tray locked inside the instrument after the read.
  • TrayLock Off

    void trayLockOff()Releases the microplate tray lock inside the instrument after the read. The tray also comes out.
