iMark Absorbance Microplate Reader
Feature Benefit
Intuitive user interface via onboard software with 64 preset or customized end-point and kinetic protocols (including food safety tests), powerful curve-fitting routines, and statistical analysis Automatically controls detection, data formats, and, analyses; reports and stores data for most complex photometric applications; configures, stores, and applies custom protocols easily
Integrated thermal printer Instant documentation
Built-in shaker with variable mixing speed Improves readout precision and minimizes variability of assays
Compatible with different types of 96-well plates (flat, U-, V-bottom) and 8- or 12-well strip plates Accommodates optimum sample conditions
Single and dual wavelength detection Detects OD specific to the reaction product and eliminates background
Motorized door for plate loading and retrieving Provides quick plate recovery and minimum environmental exposure
Fast plate reading — 6 sec at single wavelength detection Allows rapid detection of fast developing colorimetric reactions in kinetic assays using onboard software
Fast or step reading modes Fast reading or high-sensitivity detection
Eight-position filter wheel for detection by high efficiency band pass optical filters (400–750 nm). Easy to install additional detection filters. Spectral detection is reproducible, flexible, and easy to fine-tune
Options for interface with Microplate Manager software via USB2 connection to PC or Mac Customize individual protocols, reduce data, and analyze data comprehensively
Self-diagnostic capabilities to detect lamp burnout at startup Allows proactive and prompt maintenance
Multilingual (English, Japanese, Chinese, Russian) display and printed reports Adapts to localized regulatory requirements and local language standards
Checkmark reader protocols for performance validation and reporting Adapts to various IQ/OQ protocols and validation requirements
Self calibration Ensures accurate and reliable measurements for every reading

The iMark™ microplate absorbance reader, with a wavelength range of 400–750 nm, is an economical, high-performance solution for a wide range of applications, including immunoassays with colorimetric substrates, such as ELISA, and protein assays such as Bradford and Lowry. The instrument can be used as a stand-alone reader or be controlled by a PC or Mac with Microplate Manager® 6 software
