3 Disinfectant Sterile water What is Spiral method? With easyspiral automatic plater, increase your lab capacity with a counting range from 100 to 1x10 7 CFU/mL on one single Petri dish without prior dilution. Manual plating method Automatic Spiral method This method requires repetitive actions: at least 4 dilutions and 4 successive platings are necessary to obtain one good and readable Petri dish. dilution 1/10 spread 0.1 ml dilution 1/10 spread 0.1 ml dilution 1/10 spread 0.1 ml dilution 1/10 spread 0.1 ml With this method, make your analyses on 1 single Petri dish! easyspiral Pro + sample - sample All dilutions on 1 Petri dish! 1 st Petri dish 2 nd Petri dish 3 rd Petri dish 4 th Petri dish Incubation Incubation Incubation Incubation Incubation From 100 to 1x10 7 CFU/mL on 1 single Petri dish Up to 75% less consumables Full plating cycle in 25 seconds! How to count? With the Spiral method, a logarithmically decreasing volume of sample is dispensed on the surface of a rotating Petri dish in an Archimedes spiral. The volume is calibrated and known at every point of the Petri dish. Bacterial concentration is determined by dividing the number of colonies found by the volume dispensed in the same sector of the dish. For manual counting, count the colonies in the fi rst A or B outer segment and reach a minimum of 20 colonies. Repeat the same operation on the opposite side of the Petri dish.

11 interscience is proud to introduce easyspiral Dilute, a 2-in-1 automatic diluter and plater, which allows you to do 5 x 1/10 th serial dilutions. It will then automatically plate on 1 single Petri dish, with a countable range from 30 to 1 x countable CFU/mL. No more manual dilutions and plating is automatic! Place sample 2 Plate 1 Dilute Place your sample in the beaker 1. The easyspiral Dilute will automatically dilute the sample up to 5 times 2. The easyspiral Dilute will automatically plate the sample on a Petri dish up to 1 x countable CFU/mL Why use an automatic diluter & plater? easyspiral Dilute allows you to save 50% on consumables and 50% on your time.

13 How does it work? 1. Dilution cycle 1 sample Sample intake 2 sample ml of sample is deposited 3 sample ml of diluent is added to the sample and mixed The above dilution cycle is repeated for the next serial dilution. 1 sample ml of 10-1 diluted sample intake 2 sample ml of 10-1 diluted sample is deposited Dilution cycle can be repeated as many times as you wish. 2. Plating cycle Examples: Constant mode Homogenous surface deposition 50 µl, 100 µl, 200 µl and USB programmable Exponential mode Decreasing surface concentration 50 µl, 100 µl, 200 µl and USB programmable Circle mode 3 or 6 surface dilutions on 1 Petri dish 10 µl inner circle, 16 µl middle circle and 25 µl outer circle Pour mode Homogenous deposition* in pour plate mode 50 µl, 100 µl, 200 µl and USB programmable Before incubation Homogenous surface deposition + concentrated - concentrated Homogenous deposition in pour plate mode* After incubation Easy colony counting: No colonies on the edge of the Petri dish Counting on Petri dish up to 1 x CFU/mL Savings on Petri dishes Easy colony counting for invasive colonies. Pharmacopoeia compliant * In pour mode, easyspiral Dilute deposits one sample drop at the bottom of an empty Petri dish. Then, the user adds the molten agar on top and homogenizes it with the sample.

14 Questions What is special about the easyspiral Dilute? easyspiral Dilute is the only 2-in-1 equipment on the market making automatic serial dilutions and standardized plating. The accuracy of easyspiral Dilute is high: 0.5%. How can I check it? I usually dilute 1 ml to 1/10 and the easyspiral Dilute uses 0.5 ml to 1/10. Is easyspiral Dilute as precise with a volume divided by 2? It is easy and automatic. Test of the deposited volume during plating: Press on the plating volume test button. This function will fi ll a previously weighed beaker with 500 µl. Weigh the distributed volume to check the results. Test of the volume of the dilutions: Press on the dilution volumes test button. This function will fi ll 2 previously weighed beakers: one with 0.5 ml and the 2 nd one with 4.5 ml. Weigh the distributed volumes to check the results. Usually the average accuracy for the 9 ml tubes fi lling and 1 ml pipetting is 2% with the need to calibrate and regularly check the pipets you are using. easyspiral Dilute has an average accuracy of 0.5% on 0.5 ml and 4.5 ml volumes because it works with a high precision Hamilton TM glass syringe in a liquid displacement circuit. With volumes divided by 2, precision and repeatability are then much higher! Which diluents can I use? easyspiral Dilute works with saline solutions (e.g.: Ringer's solution, physiological saline). Avoid using diluents with nutrients as they may cause contaminations. Bacteria only remain a few seconds in the beakers before being deposited on the Petri dish so using a saline diluent has no effect on the fi nal enumeration. It is however possible to use nutrient solutions as diluent in the semi-automatic "My Diluent" mode. In that case, fi ll in the beakers with 4.5 ml diluent before processing. I need to make a 10-7 dilution. How can I do it? The easyspiral Dilute can do as many dilutions as you wish. Do a 10-5 dilution, take the last beaker and place it as the mother sample and then proceed with a new automatic dilution sequence. 6

17 Appendix 2. easyspiral / easyspiral Pro validation studies 1. Spiral plating method validation Purpose To study the reliability of Spiral plating with easyspiral comparing to the reference method (classical surface plating). Equipment and methods Five bacterial strains (three gram+ and two gram-) are tested: Lactobacillus casei var. rhamnosus, Bacillus cereus (ATCC 11778), Bacillus subtilis (ATCC 6633), Escherichia coli (ATCC 8739) and Pseudomonas aeruginosa (ATTC 9027). Bacterial cultures are diluted in buffered peptone water then plated on Petri dish agar (90 mm), using classical method and Spiral method (50!L in exponential mode). After 48h of incubation at 37 C (±1) on MRS (De Man, Rogosa, Sharpe) for Lactobacillus casei and 18h (±2) at 37C (±1) on PCA (Plate Count Agar) for Bacillus cereus, Bacillus subtilis, Pseudomonas aeruginosa and on Macconkey for Escherichia coli, counting is made with an automatic colony counter (Scan 1200). Results analysis Counting results are expressed in Log CFU/mL (Colony Forming Unit) and a regression analysis is made to assess the correlation between, Spiral method with easyspiral Pro and classical plating method. Results - Bacillus cereus: Spiral method (Log CFU/mL) y = 0,974x + 0,0217 R2 = 0, Classical method (Log CFU/mL) Figure 1: Correlation between Bacillus cereus counting (Log CFU/mL) obtained by plating in classical and Spiral method. 85/125 easyspiral / easyspiral Pro : Guide d installation et d utilisation V3

19 - Escherichia coli: 5.5 Spiral method (Log CFU/mL) y = 0,9822x + 0,0853 R 2 = 0, Classical method (Log CFU/mL) Figure 4: Correlation between Escherichia coli counting (en Log CFU/mL) obtained by plating in classical and Spiral method. - Pseudomonas aeruginosa: Spiral method (Log CFU/mL) y = 0,9632x + 0,1039 R 2 = 0, Classical method (Log CFU/mL) Figure 5: Correlation between Pseudomonas aeruginosa counting (en Log CFU/mL) obtained by plating in classic and easyspiral pro method. Conclusion Results show a strong correlation (R 2 " 0.982) between Spiral method with easyspiral Pro and Classical method. Hence the average difference of CFU/mL log between the two methods is resulting to be not significatif 12 times lower than the maximal deviation (0.5 log) authorised by AFNOR NF V08/ /125 easyspiral / easyspiral Pro : Guide d installation et d utilisation V3
