Abstract: A disposable staining system is provided including an insertable module configured to receive a biological sample therein, the insertable module including a well in which the biological sample is positioned; and a staining cartridge configured to receive the insertable module including the biological sample therein, the insertable module being positioned in the staining cartridge. The insertable module has first and second inclined planes on opposing sides of an upper surface of the insertable module. A sled configured to receive the insertable module has corresponding first and second inclined planes on a bottom surface thereof. The first and second inclined planes of the insertable module and the first and second inclined planes of the sled are configured to transform horizontal movement of the insertable module into the staining cartridge into a vertical movement of the sled such that the sled is pushed upward.

Abstract: A water-in-oil-in-water multiple emulsion comprises a continuous aqueous phase having dispersed therein oil phase droplets wherein each oil phase droplet contains an inner dispersion of aqueous phase droplets, a water-soluble or water-dispersible active material being dissolved or dispersed in the inner dispersion of aqueous phase droplets and at least one of (a) the inner dispersion of aqueous phase droplets and (b) the oil phase droplets being encapsulated within a polymer wall material.
