    • A device and method to provide a simplified wash process and controlled disintegration of a soft substance, such as a gel, are disclosed. In use, a block of, e.g., gel matrix is placed in the device and washed with a series of appropriate solutions to remove interfering contaminants. The washing liquid is removed through a deformable narrow opening in the bottom of the device, and, subsequently, the gel block is extruded through the deformable narrow opening, by a physical force, such as centrifugal force, a vacuum or positive pressure from a gas or liquid, etc., resulting in fragmentation of the gel block into a series of particles of similar size. The fragmentation of the gel results from shear forces exerted onto the gel block traveling through the deformable narrow opening in the device. The rate of such fragmentation and resulting fragment size can be controlled by extruding the gel block using a predefined level of force as well as by controlling the dimensions and shape of the narrow opening (s) in the device.
    • 公开了一种提供简化的洗涤过程并控制软物质如凝胶的分解的装置和方法。 在使用中,将一块例如凝胶基质置于装置中并用一系列适当的溶液洗涤以除去干扰的污染物。 洗涤液体通过设备底部的可变形的窄开口被去除,随后,凝胶块通过物理力,例如离心力,来自气体的真空或正压挤压通过可变形的窄开口 或液体等,导致凝胶块破碎成一系列类似尺寸的颗粒。 凝胶的断裂是由施加在凝胶块上的剪切力所引起的,该凝胶块穿过装置中的可变形的窄开口。 可以通过使用预定水平的力挤压凝胶块以及通过控制装置中的窄开口的尺寸和形状来控制这种碎裂和所得碎片尺寸的速率。
