In some embodiments, the deformable portion is in at least one of a base and sidewall of the vessel body. In some embodiments, the deformable portion is deformed according to a deformable pattern. In some embodiments, the deformable portion is deformed via a deformation plate having one or more movable members that contact the deformable portion.

HIGH THROUGHPUT RADIOCHEMISTRY SYSTEM

A radiosynthesis system is disclosed that leverages droplet microfluidic radiosynthesis and its inherent advantages including reduction of reagent consumption and the ability to achieve high molar activity even when using low starting radioactivity. The radiosynthesis system enables the parallel synthesis of radiolabeled compounds using droplet-sized reaction volumes. In some embodiments, a single heater is used to create multiple reaction or synthesis sites. In other embodiments, separate heaters are used to create independently-controlled heating conditions at the multiple reaction or synthesis sites. In one embodiment, a four-heater setup was developed that utilizes a multi-reaction microfluidic chip and was assessed for the suitability with high-throughput radiosynthesis optimization. Replicates of several radiochemical operations including the full synthesis of various PET tracers revealed the platform to have high repeatability (e.g., consistent fluorination efficiency). The system may also be used for synthesis optimization.

Systems for Operating Microfluidic Devices

Systems for operating a microfluidic device are described. The systems comprise a first surface configured to interface and operatively couple with a microfluidic device and a lid configured to retain the microfluidic device on the first surface. The lid comprises a first portion having a first fluid port configured to operatively couple with and flow fluidic medium into and/or out of a first fluid inlet/outlet of the microfluidic device and a second portion having a second fluid port configured to operatively couple with and flow fluidic medium into and/or out of a second fluid inlet/outlet of the microfluidic device. The second portion of the lid is separable from the first portion and movable between a closed position in which the second fluid port of the second portion of the cover is operatively coupled with the second fluid inlet/outlet of the microfluidic device and an open position in which a portion of the microfluidic device that contains the second fluid inlet/outlet is exposed. Other embodiments are described.

Automated System and Method for Single Dye Volumetric Verification and Calibration of Automated Liquid Handling and Pipetting Systems
20220404269 · 2022-12-22 ·

The method presented here is used to determine the volume dispensed by any liquid handling device (automated or manual) . A reference curve is first generated by spectroscopically reading a fixed-volume set of known, variable-concentration derivatives of a single dye. During testing the liquid handling device dispenses a yet undetermined volume of known-concentration dye into a known volume of diluent which results in a new dye concentration (resultant concentration). The absorbance of the resultant concentration is then compared to the absorbance vs concentration relationship of the earlier generated reference curve to determine the volume of dye (hence volume) dispensed by the liquid handling device. This method is an alternative to the dual dye and gravimetric volume verification methodologies. It considers and corrects for the uncertainties found in a traditional single dye approach as stated in the IWA-15 ISO standard. The system and method is distributed in bundled kits including but not limited to standardized labware, a calibrated reference pipette, a proprietary Validation Reference Plate (VRP) which automates reference curve generation, a spectrophotometer calibration plate for NIST Traceability, an environmental monitor, reference reagents, test reagents, an apparatus for quality assurance and control during manufacturing, and proprietary software for data analysis and reporting.

Automated seed sampler and methods of sampling, testing and bulking seeds

An automated method for sampling seeds generally includes removing material from a seed at an automated sampling station and then, after removing the material from the seed, detecting, by at least one sensor, movement of the seed out of the automated sampling station. The automated method may also include, after removing the material from the seed, transferring the seed from the automated sampling station to a seed container and transferring the material removed from the seed from the automated sampling station to a sample container.
