HI, Julien, We have found atleast 10ml of water resudue on head after filteration. Do we need to open the head every time to ensure contamination free operation ?? Second thing is , this entrire operation need further validation as there are many concerns as mentioned bleow, 1) Water residue inside head can lead to bacterial growth and contaminate the Analysis. 2) detaching the membrane from funnel is require more precision compare to usual Filtration method. 3) using the funnel lead as petriplate require validation.
Hi Gael, as it´s mention on the User Guide, drops could remain into the groove of the head not affecting the filtration. Just remove them with a dry wipe and also get sure you are following the dry out step correctly. Hope this helps !
Hi Julie, not sure I do understand correctly your question but the funnel is the part to help to filtrate the product. The culture media plate, is where we put the membrane to let the bacterias grow. Is it answering your question ??

Hi Julien! What is the difference between using the growth promotion accessory and using a funnel? Thanks!
