Samples can be measured at concentrations up to 4 times higher than in standard cuvettes without diluting. OD values were corrected to 1-cm values using PathCheck Technology. Dispense reagent in replicates into the microplate, then measure pathlength in a SpectraMax instrument using PathCheck Sensor. Download PDF. The results indicate that the absorbance of the yellow buffer at nm in a standard 1 cm cuvette was 0. Isothermal when temperature regulation is not enabled. Kinetic Read Intervals Microplate. Note: To avoid errors due to evaporation, make the readings within a few minutes of putting the samples in the microplate. Select to perform an endpoint read at the desired wavelength s.

  • PathCheck is applicable to almost all biological/pharmaceutical molecules in Read the plate in the SpectraMax instrument using PathCheck Sensor and. Learn how PathCheck technology can automatically correct optical density measurements to a 1-cm pathlength using Molecular Devices microplate readers. band, located in a spectral region where most biological molecules have little or no Launch SoftMax Pro Software, then open a Plate Section or, if necessary.

    Molecular Devices SpectraMax Plus Microplate Reader Marshall Scientific

    Reader from Molecular Devices can run both standard up to in a single plate read using any standard Molecular Devices' PathCheck® Sensor—the.
    The optical beam in a microplate well is vertical, so the pathlength depends on the volume of fluid and the degree of meniscus formation. Home Resources Application Note.

    Pathlength correction is intended for use with aqueous solutions, although small quantities of organic solvents can be tolerated if the PathCheck measurements are made with a cuvette reference. Figure Figure 5.

    PathCheck Sensor measures pathlength using the absorbance peak of water in the near infrared NIR spectral region. Also, any molecule with differential absorption at and nm will interfere if present in a high enough concentration.

    Our primary goal is to offer products that are as close to new as possible at an affordable price. SoftMax Pro Software software then automatically calculates the pathlength by comparing the peak height in each well to the peak height in a standard 1 cm cuvette.

    PathCheck is patented by Molecular Devices and can be performed only on an.
    Turbidity is one source of interference. Download PDF. To avoid errors due to evaporation, take the readings within minutes of putting the samples in the microplate.

    All electronics and boards are tested for proper function and response by our industry trained technicians.

    The PathCheck Sensor a Powerful Tool for Microplate Analyses Molecular Devices

    PathCheck utilizes absorbance of water at nm to ensure results that are independent of temperature. Raw, uncorrected OD values ranged from 0. Can easily test performance of multichannel pipettors and automated liquid handlers by detecting volume differences.

    Two potential causes of erroneous results are evaporation and failure to apply a Plate Background OD. PathCheck Sensor measures pathlength using the absorbance peak of water in the near infrared NIR spectral region. All Products Come with a Standard Warranty. Note: for SpectraMax microplate readers without a cuvette port, the water constant is automatically used in PathCheck calculations, and no Water Constant option appears in the Instrument Settings.

    As expected, the uncorrected absorbance values increase with increasing pathlength i.

    The Molecular Devices SpectraMax Plus is a UV/Vis This is accomplished by PathCheck, in conjunction with the SoftMax Pro software, automatically is equipped with a built-in programmable linear and orbital plate shaking device. operation of such Molecular Devices equipment, software, reagents, and consumables.

    The effect is particularly noticeable in wells with small volumes. Note: Cuvette Reference is only available when using an instrument with a cuvette port. Stray Light. Read the plate in the SpectraMax instrument using PathCheck Sensor and display the data using grayscale to highlight any irregularities.

    Read absorbance on the SpectraMax microplate reader at the wavelength to be used for your assay, and average the resulting OD values for all wells to obtain the Plate Background OD.
