Multimode Microplate Reader

Modulus Multimode Microplate Reader

User-friendly operation – touch screen control, data download onto USB stick         MMReader

Microplate format - Accepts 96-well plates conforming to the SBS plate standard

3 Detection Modes: Luminescence, Fluorescence, Visible Absorbance

Compatible with most commercially available kits




  Luminescence Module:

- >8 Logs Dynamic Range

- Dual-masking System Reduces Crosstalk
- Very high sensitivity



The Luminescence module is separated from other measurement technologies and positioned directly above the sample well, maximizing light capture for increased sensitivity, with a detection limit of 3 x 10-21 moles Luciferase Detection or 1 x 10-18 moles ATP. The head-on photomultiplier tube has a spectral range of 350-650 nm and automatically adjusts for the optimum reading of bright or dim samples.

Dual auto injectors are available for flash-based luminescence applications or dual-reporter assays. Each injector system has a volume range of 25 - 200 µl in 5µl increments.


 Fluorescence Module

- Epifluorescent Detection
- Multiple Optical Kits Available
- High Sensitivity

                flor. DNA

The Fluorescence module uses powerful wave-length matched, light-emitting PIN photodiodes (LEDs) as excitation sources. The narrow excitation/emission spectrum increases sensitivity and reduces non-specific light leakage. The fluorescence capability has a maximum linear dynamic range of 6 logs and a detection limit of 0.5 fmol/200 µl or 1 ppt of fluorescein in a 96-well plate, or 30 pg/well dsDNA with a DNA quantification dye
