An espresso-coffee making apparatus comprising a brew water tank at least one heating device for the purpose of heating the brew water, and a pump operatively engaged to the brew water tank with both its inlet and outlet. The pump outlet is attached to a housing such that the pump's discharge moves past the heating device for effective mixing at the heat source. The housing may also include turbulators for further enhanced mixing. Thus, maximum temperature homogeneity within the brew water tank is achieved. The apparatus may further comprise a biasing device operatively engaged to a piston-type pump via a linkage mechanism. Wherein the biasing device is energized by the operator, by means of a lever and the pressurized water produced used to brew espresso. Further, the pressure of the water produced by the pump is modified by the linkage mechanism such that the brew pressure as a function of displaced liquid is controlled. Thus more optimal brewing pressure profiles can be achieved.

The invention discloses a preparation method for small-particle-size magnetic agarose microspheres. According to the preparation method, emulgator and hydrophobic organic solvent serve as an oil phase, mixed liquor of agarose and superparamagnetic Fe3O4 aqueous solutions serves as an aqueous phase, the aqueous phase is added into the oil phase under mechanical stirring to carry out pre-dispersion, then ultrasonication is carried out on pre-dispersion emulsion, and cooling, magnetic separation and purification are carried out on the crushed emulsion to obtain the small-particle-size magnetic agarose microspheres. The magnetic agarose microspheres prepared according to the preparation method have high magnetic response and superparamagnetism, and compared with commercially available products, the magnetic agarose microspheres have smaller particle sizes, larger specific surface areas, more active sites, and broad application prospects.
