Bonjour, je travail sur un projet d'extraction et séparation des hémicelluloses issus du bois. je souhaite des conseils sur les filtres a utiliser pour la séparation solide liquide de l’hydrolysât obtenu après extraction (taille des pores, nature...) ainsi pour faire une micro-filtration avant de passer à l'ultrafiltration des hémicelluloses. Je suis intéressé aussi par les filtres nécessaires à la filtration des hémicelluloses avant leur analyse par chromatographie d'exclusion stérique. Merci de m'envoyer toutes les informations nécessaires ainsi que les devis des filtres dont j'aurai besoin. Bien cordialement
