Abstract: A viscometer comprises a liquid feeding conduit opening into a measuring chamber and a capillary liquid outlet conduit connected to said chamber, pressure-sensitive means associated with said chamber for sensing the pressure variations in the latter, converting means for converting the pressure variations sensed by said pressure sensitive means into measurable and displayable quantities of value, said feeding and capillary conduits and said pressure-sensitive means being enclosed in a metallic block arranged in a heat-insulated space which includes heating means for heating said block, said heating means being adapted to maintain the temperature of said block at an adjustable predetermined value.

Abstract: From an aqueous medium derived from milk substantially free from caseins, proteins are extracted, particularly lactoferrine and immunoglobulins, by adsorption on a solid support. The aqueous medium is weakly basic, while elution is effected by means of an acid solution.

Abstract: A novel process of separating from an aqueous medium at least one protein or at least one morphologically organized unit by liquid exclusion chromatography on a solid support previously passivated by treatment with an aqueous solution of a non-proteinic polymer. In this process, the chromatographic support is submitted, prior to the chromatographic operation, to a second passivation consisting in contacting the support with an aqueous solution of a protein which has a molecular weight lower than that of the protein to be separated, and which is adapted to be adsorbed by said support. The support and/or the liquid to be treated are sterilized with antiseptic agent selected from the group constituted by the lower aliphatic halogenated hydrocarbons.
