Systems and methods are provided for collecting a platelet product having a target concentration. First and second target concentrations are first selected. Blood is then separated into red blood cells and platelet-rich plasma, with the platelet-rich plasma then being separated into platelet-poor plasma and platelet concentrate. At least a portion of the platelet concentrate is collected in a container as a platelet product having an actual platelet concentration, attempting to collect platelet concentrate having the first target concentration. After separation of the blood has been completed, at least a portion of the platelet-poor plasma and/or an additive solution is pumped into the container to decrease the concentration of the platelet product from the actual platelet concentration to the second target concentration.

The present invention provides for a method for separating starch from processing solutions containing starch containing plants or roots such as potatoes, sweet potatoes, wheat, corn, tapioca, yams, cassaya, sago, rice, pea, broad bean, horse bean, sorghum, konjac, rye, buckwheat and barley to provide commercially acceptable starch while reducing disposal of solid or liquid waste matter into landfills or water treatment facilities.

The present invention provides a device for separating and purifying the collagen Type 2 in chicken bones, comprising a liquid fluid container, a raw liquid container, a membrane separation tank, a mixing tube, two high pressure metering motors, a precooler, two preheaters, a temperature controller, two one-way valves, two inlet control valves and two outlet control valves. The liquid extract of defatted chicken bones discharged from the raw liquid container and the liquid CO2 discharged from the liquid fluid container can be mixed uniformly in the mixing tube, and then fed into the membrane separation tank. The membrane separation tank produces small-molecular-weight peptides and large-molecular-weight collagen Type 2 harmlessly and efficiently.

The system and method for pretreating turbid seawater utilizes polyelectrolyte dosing, clarification through a clarifier system and centrifugation in a decanter centrifuge followed by microfiltration to treat seawater prior to its injection through a desalination plant. The system for pretreating turbid seawater includes a static mixer for mixing a polyelectrolyte with a stream of turbid seawater to produce a polyelectrolyte-treated seawater mixture. At least one clarifier tank is in fluid communication with the static mixer for receiving the polyelectrolyte-treated seawater mixture and removing a first portion of solids therefrom to produce a clarified seawater mixture. A decanter centrifuge is in fluid communication with the at least one clarifier tank for receiving the clarified seawater mixture and removing a second portion of solids therefrom to produce centrifuged seawater. A microfiltration system is in fluid communication with the decanter centrifuge for receiving the centrifuged seawater to produce the pretreated seawater.

A mitochondria extraction apparatus provided in the present invention includes a container used for holding a mixture fluid and a diafiltration assembly disposed in the container and used for isolating mitochondria. A basement of the mitochondria extraction apparatus is disposed in the container. During a circular motion of the mitochondria extraction apparatus, a centrifugal force in the mitochondria extraction apparatus acts on the mixture fluid in a hole-shaped microfluidic channel included in the diafiltration assembly, so as to provide a pushing force for the mixture fluid, enabling the mixture fluid to rapidly flow in the microfluidic channel for diafiltration.

A cell filtration assembly adapted to capture cells from a biological sample during centrifugation includes a centrifugation tube, a cell collection device adapted to be secured within a tapered end of the centrifugation tube and a funnel structure adapted to direct fluid into the cell collection device. The cell collection device includes a rectilinear structure that is adapted to permit fluid to flow through the rectilinear structure and a cell capture surface that is secured relative to the rectilinear structure. The cell collection device may be sectioned in either a horizontal or vertical orientation.

Filtration devices and methods for collecting, filtering, and/or processing biological samples are disclosed. An example filtration device may include a funnel member having a first end region and a second end region. A flange may be coupled to the first end region. A filter support portion may be coupled to the second end region. The filter support portion may include a base, a filter membrane coupled to the base, and a securing member for securing the filter membrane to the base.
