  • Publication number: 20220146544
    Abstract: Aspects of the present disclosure relate to evaporation compensation in fluidic devices. An example apparatus for evaporation compensation includes an assessment circuit to determine an amount of evaporation of a volume dispensed in a microwell of a fluidic device. The amount of evaporation may be determined based on the volume in the microwell, and an amount of time after dispensing the volume in the microwell. A compensation circuit may determine, based on the amount of evaporation, a compensation factor for the microwell including an amount of a normalizing fluid to compensate for the amount of evaporation. The compensation circuit may also create a normalization profile for the fluidic device, including an association between the fluidic device and the compensation factor. A dispensing circuit may dispense the normalizing fluid in the microwell according to the normalization profile.

  • Patent number: 11007529
    Abstract: According to an example, a microfluidic apparatus may include a fluid slot, a foyer in fluid communication with the fluid slot via a channel having a relatively smaller width than the foyer, a sensor to detect a presence of a particle of interest in a fluid passing through the channel, a nozzle in fluid communication with the foyer, and an actuator positioned in line with the nozzle. The microfluidic apparatus may also include a controller to receive information from the sensor, determine, from the received information, whether a particle of interest has passed through the channel, and control the actuator to expel fluid in the foyer through the nozzle based upon the determination.

  • Publication number: 20210088540
    Abstract: In example implementations, a method is provided. The method may be executed by a processor of a fluid dispensing apparatus. The method includes detecting a pause signal due to a surface load error. Corrective actions are initiated in response to the pause signal. A continue signal is received after the corrective actions are completed and a correct microplate is loaded into the fluid dispensing apparatus. Fluids are then dispensed into wells of the correct microplate.
