Abstract: A system for measuring flow rates of fluid flows to parallel reactors includes a common feed line, a plurality of reactor feed lines for receiving a reactor fluid flow, a measurement line, and a valve system. The valve system includes one or more valves and a valve control unit for controlling the one or more valves, the valve system being arranged and/or adapted such that it can assume a measurement setting in which the valves redirect one of the reactor feed flows such that it flows through the measurement line.

Abstract: A flow controller assembly for microfluidic applications includes at least one microfluidic flow controller, which includes a microfluidic chip, a thermal energy transmitter, a flow sensor for measuring the flow rate of a fluid running through the flow controller and a data control unit. The data control unit, which is connected to the flow sensor by a first data connection which allows the data control unit to receive flow rate measurement data from the flow sensor, and which is also connected to the thermal energy transmitter by a second data connection allows the data control unit to influence the thermal output of the thermal energy transmitter, includes a data processing unit that determines the difference between the measured flow rate and a preset desired flow rate and to regulate the thermal output of the thermal energy transmitter in order to obtain or maintain the desired flow rate.

Abstract: A stir system for stirring a liquid in a vial includes a top for at least partially closing the vial and a stirrer rotatable mounted in the top. The stirrer extends from the top into the vial and the stirrer is being connected with a magnet, which is rotatable during use by a rotating magnet field so as to rotate the stirrer in the vial. The system further includes a holder for holding the vial and a cover for covering the vial in the holder.

Abstract: The invention relates to a sample analysis apparatus. The apparatus comprises: a radiation system to irradiate the sample in a vial and an analyser with a camera to analyse the radiation received from the sample in the vial. The apparatus is provided with a holder to releasable hold the vial and with an optical path for the radiation system to irradiate the sample and for the camera to make images of the sample. The radiation system can be used for front lighting of the sample in the vial or for back lighting of the sample in the vial. The camera may be provided with a telecentric lens.

Abstract: The invention pertains to reaction systems in which at least one capillary unit is applied.
