VWR propose un éventail de solutions tampons pour répondre aux besoins spécifiques des procédures chimiques et microbiologiques en laboratoires. Pour isoler et séparer les protéines lors du processus d'électrophorèse, l'utilisateur pourra sélectionner des tampons en poudre ou liquides qui protègent et suivent les échantillons protéiniques durant le process. Une large gamme de tampons de pH, de compositions et de formats différents est proposée pour la calibration et la normalisation des pH mètres. Pour la purification et la récupération des protéines dans des procédés de chromatographie, sélectionnez des tampons dans des formats adéquats aux procédures d’échange d’ions. La plupart des tampons sont disponibles en concentrés liquides, dans des bouteilles prêtes à l’emploi ou dans des formats déshydratés.
