Biochrom Asys Expert Plus Microplate Reader

Biochrom Asys Expert Plus Microplate Reader
  • Standalone microplate reader supplied with 4 filters (405, 450, 492, 620 nm)
  • Multichannel reading, ideal for labs requiring simple rapid reading of microplates
  • Both onboard and PC software options for flexibility in analytical requirements
  • QC plate and QC software for instrument validation for peace of mind
  • Designed for simple rapid absorbance assays

The Biochrom Asys Expert Plus is a standalone modern design multi-channel microplate reader, for fast plate reading of standard ANSI SBS footprint 96 well, flat, round and v-bottomed plates. The Biochrom Expert Plus has four shaking modes for mixing of solutions and the ability to perform readings at timed intervals ideal for kinetic assays.
Four filters are supplied as standard that cover common absorbance assays. Filters from 400 up to 800 nm can be purchased separately when more specialised assays are required.

Choose the software options to meet your needs
The Biochrom Asys Expert Plus has onboard software for instrument control and data analysis. The onboard software enables instrument control, complete plate setup, plus qualitative, quantitative and kinetics, and a range of curve fit methods, including parabolic, cubic, point to point, spline and 4 parameter fit. Assay formulas can also be setup including validation outliers, elimination, transformation factors and floating cut-offs.
The onboard software can store upto 120 methods and the results of upto 100 plates.

PC-control of the Biochrom Asys Expert Plus for additional analytical capabilities
The standalone Biochrom Expert Plus can be operated in remote mode using PC software. The instrument is supplied with DigiRead which can control the plate reader and allow raw data to be transferred to a Microsoft® Excel spreadsheet for further analysis and Control Plus PC software which simulates the onboard software and allows both methods and raw data to be uploaded and downloaded to and from a PC.

Optional PC software packages:
• KIM is a data reduction package including end-point assay requirements for 96-well plates, and the ability to design bespoke reports

Designed for ELISA's, enzyme immunoassays, protein quantitation (BCA, Lowry, Bradford), cell proliferation, and cell survival assays, plus cell based assays where shaking is required to keep cells in suspension, enzyme kinetic assays, and high throughput assays where rapid plate reading is required.

Downloadable assay methods
The Biochrom Asys Expert Plus can be downloaded with methods for the Biotrak Assays from GE Healthcare http://www.biochrom.co.uk/user_downloads/?c=19
