The iMark microplate absorbance reader offers fast reading speeds, extensive onboard software capabilities, a preprogrammed validation protocol and a built-in printer in a compact, lightweight unit. The instrument can be used as a stand-alone reader or controlled by a PC or Macintosh with Microplate Manager™ Software. The wavelength range of the iMark reader is 400–750 nm, permitting many applications, including enzyme-linked immunosorbent assays (ELISAs) with colorimetric substrates, protein assays (Bradford and Lowry), and DNA quantitation.
The iMark instrument reads an entire 96-well plate in 6 seconds in Fast Read mode and performs dual-wavelength reads in 10 seconds. Kinetic reading can also be programmed with onboard software or controlled by Microplate Manager software. The iMark reader’s onboard software is well suited for life science and clinical laboratories. The software includes security login features that allow locking and unlocking of key protocol settings by the administrator, generous memory capacity for protocol creation and storage storage, comprehensive curve-fit selections and extensive reporting functions. Onboard software includes preprogrammed protocols for Bio-Rad’s Checkmark reader performance check plate to validate the installation qualification/ operational qualification/performance qualification (IQ/OQ/PQ) of the iMark reader in compliance with GLP. Other life science and clinical protocols are also included, such as those for the Bio-Rad TSE kits and a growing number of clinical testing kits.The iMark reader comes with 4 standard absorbance filters: 415, 450, 490 and 655 nm. There are 7 additional filter options: 405, 540, 550, 570, 595, 630 and 750 nm. Bio-Rad also supplies custom filters at 5 nm intervals from 400 to 750 nm on request. A wide-format internal thermal graphical printer saves counter space and simplifies stand-alone operation. The iMark reader can also be used with an external printer with or without a data station.
