Product Description

The Labmart EMR4 ELISA Microplate Reader is a specialized microplate analysis instrument designed for ELISA applications and scientific research requiring accurate and reliable absorbance measurement of samples in 96-well plates. It features a 7-inch colour touchscreen, Android operating system, halogen lamp, 8-position filter wheel and built-in software for instrument control and data analysis. 

Product Overview

The EMR4 ELISA Microplate Reader is designed for enzyme-linked immunosorbent assay applications. The instrument uses a fixed-wavelength filter system to measure light absorbance in microplates and provides a means to quantify substances through analysis of colour changes in ELISA tests.

The supplied 2025–26 catalogue specifies an 8-position filter wheel, with four standard filters included at 405 nm, 450 nm, 492 nm and 630 nm, while allowing up to eight filters to be loaded. The wavelength range is 340–750 nm.

The EMR4 provides both Standard and Fast measurement modes, with whole-plate detection of a 96-hole plate in less than 6 seconds in fast measurement mode. It also incorporates automatic calibration and positioning, instrument self-diagnostics, built-in software and USB connectivity.
