1. Dilute the sample
Automatic method
Gravimetric dilutors
![Automatic dilution with DiluFlow Automatic dilution with DiluFlow](IMG/png/comparaison_panneau1_auto_680x650.png)
Automatically dilute the sample with the appropriate mass of diluent.
- Fast: 225 mL in 8 s
- Dilution accuracy: > 99% (in Standard or Accurate mode under optimal conditions)
- Reproducible
- Secure
- Automatic traceability

Manual method
Manual dilution
![Weight and dilute a the sample Weight and dilute a the sample](IMG/png/comparaison_panneau1_manuelle_680x650.png)
Weigh the sample and manually add the diluent.
- Long and tedious
- Lack of precision
- Not reproducible
- Lack of security
- Manual traceability
2. Blend the sample
Manual method
Laboratory blenders
![Blending the sample with BagMixer Blending the sample with BagMixer](IMG/png/comparaison_panneau3_auto_680x650.png)
- Time saving on cleaning
- Filtration and blending
- No cross-contamination
- Optimal bacterial extraction
Our laboratory blenders

Manual method
Sample grinding
![Sample grinding in a blender Sample grinding in a blender](IMG/png/comparaison_panneau3_manuelle_680x650.png)
- Time consuming cleaning
- No filtration
- Risk of cross-contamination
- Undesirable cell lysis
3. Collect the filtrate
Automatic method
Filter bags for blenders
![Collect the filtrate in an interscience filter bag Collect the filtrate in an interscience filter bag](IMG/png/comparaison_panneau3_auto_680x650-2.png)
Diluted and blended sample particles in the bag
Microorganisms to be analyzed
- Instant filtration
- Easy pipetting

![Blender bags with filter Blender bags with filter](IMG/png/sacs-filtre_250x250.png)
Manual method
Bag without filter
![Collect the filtrate in a bag without filter Collect the filtrate in a bag without filter](IMG/png/comparaison_panneau3_manuelle_680x650-2.png)
- No filtration
- Blocked pipette
4. Dilute and plate the sample
Automatic method
Automatic platers
![Automatic plating with easySpiral Automatic plating with easySpiral](IMG/png/comparaison_panneau4_auto_680x650.png)
- From 100 to 1x107 CFU/mL on 1 Petri dish
- Up to 75% savings in consumables
- Automatic traceability to automatic colony counters with dataLink

Manual method
Manual plating
![Manual serial dilutions Manual serial dilutions](IMG/png/comparaison_panneau4_manuelle_680x650.png)
- Repetitive action method: 4 dilutions + 4 successive platings
- Lots of consumables
- Manual traceability
5. Counting the colonies
Automatic method
Automatic colony counters
![Simplified counting with filter bag - Correlation for automatic counting Simplified counting with filter bag - Correlation for automatic counting](IMG/png/comparaison_panneau5_auto_680x650_en.png)
- Counting is simplified with the use of a filter bag
- Standardized and reproducible results (Study conducted on Bacillus cereus, Escherichia coli and Lactobacillus casei.)
- Results exported and archived automatically
