SEPARATION OF LIQUID IN DROPLETS AND SEDIMENTED MATERIAL ENCLOSED THEREIN
The invention relates to methods for drawing-off liquid from individual droplets which are in a predefined arrangement on a flat substrate and have sedimented material enclosed in them. A mask of an absorbent material comprising a pattern of indentations or holes which corresponds at least partially to the regular arrangement of the individual droplets, or a stiff, rigid plate of an absorbent material is positioned above the flat substrate in such a way that the droplets come into contact with the absorbent material peripherally so that liquid is drawn off there-into. The invention also relates to a mask of an absorbent material with a substantially rectangular shape which has a predefined pattern of indentations or holes for the purpose of separating liquid and sedimented material enclosed therein.
Recognizable carrier for optical measurement methods
The invention relates to a recognizable carrier for determining physical, chemical or biochemical interactions by means of optical measurement methods. The carrier comprises a surface that defines a substrate surface and that has a base layer coated with reactive elements, which are bonded to receptor molecules, wherein the base layer and/or the reactive elements are provided with a pattern of holes which forms a code and/or the reactive elements are provided with linker molecules or markers which form a code. The substrate surface may additionally have a macroscopically planar pattern which is applied using laser light or chemical etching and forms a code. The invention likewise relates to a method for producing a recognizable carrier for spectroscopic processes and/or intensiometric tests to determine said interactions. The code to recognize the carrier can be controlled via a read-out unit coupled to the photometric analysis unit. Such a carrier can be used to analyze biomolecules during security checks, access controls or in-vitro diagnostics.

Automated modular system and method for production of biopolymers
The present invention provides an automated modular system and method for production of biopolymers including DNA and RNA. The system and method automates the complete production process for biopolymers. Modular equipment is provided for performing production steps with the individual modules arrange in a linear array. Each module includes a control system and can be rack mounted. One side of the array of modules provides connections for power, gas, vacuum and reagents and is accessible to technicians. On the other side of the array of modules a robotic transport system is provided for transporting materials between module interfaces. The elimination of the requirement for human intervention at multiple steps in the production process significantly decreases the costs of biopolymer production and reduces unnecessary complexity and sources of quality variation.

Method of and System for Printing In-Well Calibration Features
An apparatus and a method are disclosed for printing in-well calibration features onto assay substrates. An apparatus includes a testing substrate; a plurality of capture compound features in a well of the testing substrate; a calibration feature on one of the capture compound features in the well of the testing substrate, where the calibration feature has a known concentration of a compound that is capable of binding to the capture compound; and at least one additional capture compound feature in the same well of the testing substrate, where the at least one additional capture compound feature does not have a calibration feature printed onto the at least one additional capture compound feature. Methods for using the same are disclosed.
Well plate and suction device provided with well plate
A well plate is formed with a well for holding a subject to be sucked by a suction nozzle on an inner bottom part and storing liquid and, a clearance forming member for forming a clearance to allow the liquid to flow in a state where a tip part of the suction nozzle is inserted into and held in contact with the well is provided in the well. According to the present invention, the clearance enabling the liquid to flow is formed even in the state where the tip part of the suction nozzle is inserted into and held in contact with the well in sucking the subject held in the well by the suction nozzle. The suction nozzle can suck the liquid around through the clearance and the subject held in the well is efficiently sucked through the suction port along the flow of the sucked liquid.
