摘要:
Using phase separation technique perforated as well as non-perforated polymeric structures can be made with high aspect ratios (>5). By varying the phase separation process the properties (e.g. porous, non-porous, dense, open skin) of the moulded product can be tuned. Applications are described in the field of micro fluidics (e.g. micro arrays, electrophoretic boards), optics, polymeric solar cells, ball grid arrays, and tissue engineering.

A device for generating microspheres from a fluid includes an injection plate with at least one defined injection channel having on an inlet side an inflow opening for receiving the fluid and on an outlet side an outflow opening for delivering microspheres formed from the fluid. The device includes feed elements for carrying fluid through the injection channel and is in open communication, on a side wall thereof, with at least one secondary channel at least at the position of a break-up point where at least during operation a flow of fluid in the injection channel breaks up into separate parts. The secondary channel includes in use an auxiliary fluid at least at the position of a break-up point.

Nozzle device and nozzle for atomisation and/or filtration as well as methods for using the same. The present invention relates to a nozzle and nozzle device for atomisation, in particular a micro-machined reinforced nozzle plate, that may produce small liquid droplets in air (spray) or into a liquid (emulsion) with a narrow droplet size distribution and to make small air bubbles into a liquid (foam) and to methods of making the same. The invention is further related to a nozzle part for filtration as well as means and methods to facilitate atomisation and filtration.

An atomizing device, includes an atomizing body (1) with an inlet (16) for receiving a fluid under increased pressure, and with at least one set of outflow ports (18) for allowing the fluid to escape on a delivery side with forming of a vapor. Imaginary central axes of the outflow ports directed in a flow direction herein enclose a mutual angle (α) in order to intersect each other at an intersection (S). The atomizing body includes a roof (21) and a bottom (11 which extend over at least a first distance (d1) beyond the set of outflow ports (18) and bound a vaporizing space (17) on either side. The intersection (S) of the imaginary central axes of the outflow ports lies at a second distance (d2) from the set of outflow ports, wherein the second distance (d2) is greater than the first distance (d1) and extends beyond the vaporizing space.

摘要:
A membrane filter comprises a membrane provided with pores with a pore size between 5 nm and 50 .mu.m. The membrane may easily and reliably be processed with use of silicon micromachining through depositing a relatively thin membrane layer on a support, by use of a suitable vapour deposition or spincoating technique, after which perforations are made in the thin membrane layer, for example by etching with aid of photo-lithography or an imprint technique. Such a membrane is very well applicable for the separation of biological cells. A membrane with a thickness smaller than the diameter of the perforations is in particular suited for the separation of vulnerable cells and may be used as a leucocyte filter or as a blood plasma separator of blood concentrates. A microfiltration membrane according to the invention may very well be applied as a support for the deposition of a separation layer for ultrafiltration, gas separation or catalysis.

A system for packaging a low acid liquid is provided herein. The system includes feeding unit configured to feed the low acid liquid into a filtration unit. The filtration unit is configured to filter the low acid liquid by using a number of pores provided on a micro sieve membrane. Further, the filtered low acid liquid is provided to an aseptic buffer unit configured to fill the aseptic filtered low acid liquid into packaging containers. The system further includes an automatic cleaning in place unit configured to automatically clean the feeding unit, the filtration unit and the aseptic buffer unit by decontamination using a decontaminating material.
