ScanRDI (ChemScan RDI outside the US)
With its unique combination of speed and sensitivity, represents a revolution in microbial detection. For the first time, direct cell counts down to one microbial cell can be delivered within minutes for viable micro-organisms. Even spores, stressed cellsand fastidious organisms can be detected within minutes.
Real-time Analyzer ScanRDI for filterable products
Combining Speed & Sensitivity!
Ultra-rapid: results within 90 min !
Direct enumeration of microorganisms
Sensitivity : down to 1 cell per sample!
Accuracy: labels all viable microorganisms (bacteria, bacteria spores, yeasts, moulds and moulds spores)
Ideal for pharmaceutical MICROBIOLOGY
Applications : process water control, non sterile products, environmental control, cryptosporidium giarda, etc.
ScanRDI : the unique combination of key performances
• From Sampling to result within minutes
• Sensitivity down to one microbial cell in a sample
• Sensitivity independent from the volume filtered (large volumes can be tested)
• No cell multiplication required
• Direct detection of bacteria, yeast, molds & spores
• Direct cell count removes the need for operator calibration and interpretation
• Linear response from 1 to 105 cells for bacteria and 1 to 104 for yeast & molds
• Non-destructive test protocol permits microscopic confirmation
• Robust and easy to use
• 21 CFR 11 compliant
• Full traceability
A quantum leap in microbial detection
Although it offers revolutionary performance, is based on two proven technologies - fluorescent cell labeling and laser scanning, and is also called Solid-Phase Cytometry. On their own each has a contribution to make towards enhanced cell detection, but when integrated together the results are truly dramatic - a quantum leap forward.
Cell LabelingAll viable microorganisms retained on the membrane are labeled with an advanced reagent system which uses enzymatic cleavage of a non-fluorescent substrate to liberate free fluorochrome into the cytoplasm. Only metabolically active cells (including spores) have the ability to perform this cleavage. Even under conditions of stress - such as the nutrient-depleted conditions of process water or in the presence of growth inhibitors - the cleavage will still occur within viable organisms. |
Laser Scanning
Scanning is fully overlapping and any cell present on the filter, |
Data Processing
To ensure only labeled microorganisms are detected and counted, ScanRDI employs proprietary powerful signal discrimination techniques.
|
Result traceability
ScanRDI provides total traceability for each analyzed sample, which simplifies compliance with accreditation |
An Investment with Immediate Return
FDA - Approved technology
• Rapid Environmental Monitoring REM: Water - Air - Surfaces
• Process water
Numerous validation studies in the US and Europe show that provides results equivalent to that of the plate-count method, but in a much shorter time frame. This advantage can be used to very efficiently address important situations such as a) Fast characterization of water systems, b) Surveillance of biofilm formation, c) Water-system trend monitoring.
• TVC Bioburden
• Anti-microbial Effectiveness Testing (AET) has a very large measuring range. For general use, there is a linearity between 1 and 105 cells per membrane for bacteria 1 and 104 for fungi. Thus, the need for multiple dilutions is dramatically reduced, thereby minimizing errors and saving time and money. It also helps develop better quality products and tests many more different formulas.
• OOS / Failure investigations
• Desinfectant efficacy, Immediate Cleaning validation
• In-process sample testing
• Final product release
• Specific tests for: Legionella pneumophila, Cryptosporidium, Giardia
• Beverages (beer, wine)spoilers detection
• Cell cultures processes (scale-up & downstream)
ScanRDI eliminates the delay in acquiring results of in-process sampling and reduce the turnaround time of a contaminated run. allows proactive control procedures and reduction in production cycle times for the scale-up and downstream processes. ScanRDI protocol provides consistent sensitivity even in the presence of up to 106 animal cells.
