There are further provided methods of screening sample fluids for predefined molecule.

A liquid droplet manipulation system has a substrate with at least one electrode array and a central control unit for controlling selection of individual electrodes of the electrode array and for providing the electrodes with individual voltage pulses for manipulating liquid droplets by electrowetting. A working film is placed on top of the electrodes for manipulating samples in liquid droplets with the electrode array. At least one selected individual electrode of the electrode array is configured to be penetrated by light of an optical detection system for the optical inspection or analysis of samples in liquid droplets that are located on the working film. Also disclosed is working film that is to be placed on the electrode array and a cartridge that includes such a working film for manipulating samples in liquid droplets.

An example apparatus includes a well plate having an array of wells, a light encoding layer positioned under the well plate, an imaging layer to capture an image of the well plate encoded by the light encoding layer, an array of electrodes positioned on a surface of a bottom floor of the at least one well, and a controller. The light encoding layer is to encode light passing through a microscopic object in at least one well of the array of wells. The light encoding layer has a substantially flat form. The controller is to direct electrical voltage to the electrodes to generate a non-rotating, non-uniform electrical field, the electrical field being to rotate an object in the electrical field.

A system for sex sorting of mosquitoes generally comprises: (i) a plate or similar receptacle that includes multiple wells, with each of the multiple wells configured to receive a mosquito; and (ii) an imaging subsystem, including a camera for capturing images of the mosquito in each of the multiple wells and a computer for analyzing the captured images to determine whether each mosquito is male or female. Mosquitoes have distinct anatomical areas for identification, which are captured in the images and are used to determine if a mosquito is male or female. Furthermore, in some implementations, the system includes a suction device or other means for exterminating the unwanted mosquitoes after the determination of whether each mosquito is male or female.

A process for freeze drying a material. The process has the steps of (a) placing material to be freeze-dried in a vessel, the vessel comprising a container having a base, and at least one wall defining an opening at one end; (b) applying a membrane to the at least one wall to thereby cover the opening, wherein the membrane comprises an aperture which, in use, is aligned with the opening; and (c) subjecting the vessel to a lyophilisation procedure, wherein the membrane is in place on the container during the lyophilisation procedure.

A treatment apparatus for treating biological cell cultures, located in respective storage chambers of a carrier, includes a work deck with one or more bearing spots for bearing the carrier. Each of the bearing spots includes a bearing region corresponding to an area of the carrier. The treatment apparatus additionally includes nozzles for producing a gas flow in a space above the work deck. To avoid liquid droplets or cell material being transported from one storage chamber to another as a result of a horizontal gas flow above the carrier during the treatment, the nozzles are arranged outside of and along an edge of the bearing region or within the bearing region and form a gas curtain around the carrier or the respective storage chambers.

A device for receiving, stacking, and removing microplates is presented and described. The device comprises a tower for stacking the microplates, wherein a microplate comprises a container and, optionally, a lid. There is a retaining device at the lower end of the tower, which has a first retaining tool and a second retaining tool, and preferably partially encompasses a microplate. The first retaining tool is designed to hold a microplate in a form-fitting manner. The second retaining tool is designed to fix a container in the microplate in place in a frictional manner. The first retaining tool is above the second retaining tool in the stacking direction. A system that comprises the device described above, a dispenser device, and a transport device, is also disclosed. The dispenser device is used to fill microplates, and the transport device is used to add and remove microplates to and from the device.

A container for the heating of samples and a system comprising such a container and provides a container for processing samples, wherein the container is made of a material comprising electrically conductive particles.

The present disclosure provides a microfluidic chip including a plurality of microcavities, at least two of the plurality of microcavities have different volumes.

Embodiments of lab automation workstations are disclosed in which the pod that performs pipetting operations is integrated with pipette tip-loading functionality. To generate the necessary tip-loading force, a dual drive system is used that is symmetric about the Y-axis to allow for offset or partial tip box loads by dynamically centering the drive force (e.g., the tip-loading force) over the reaction load. This minimizes the need for oversized linear motion components while still allowing for the generation of high tip-loading forces needed to properly load a large number of pipette tips simultaneously.
