Union Biometrica, Inc. to exhibit the VAST BioImagerâ„¢ System for rapid automated imaging of 2-7 dpf zebrafish larvae at the 11th International Conference on Zebrafish Development and Genetics

We invite you to learn about our technologies by attending the “Tools for Image Acquisition, Analysis and Increased Throughput” Workshop on Wednesday, June 25, 2014 from 4:00pm – 6:00pm at the Playhouse Theater. Speakers include:


Erica Davis/Christelle Golzio, Duke University, “Modeling pediatric genetic disorders in zebrafish: Accelerated throughput with VAST BioImager”.

Peter Eimon, MIT, “New technologies for quantitative phenotyping of zebrafish larvae”.


The VAST BioImager system meets the growing needs of toxicology researchers studying zebrafish by allowing zebrafish handling and cellular-resolution imaging tasks to be automated. The system mechanically loads each larva into a capillary, positions it laterally, and then rotates it in the field of view of the on-board camera for organ level imaging. Alternately the VAST can be mounted on a high resolution upright microscope for high content bright field or fluorescent imaging at the cellular level.  Our LP Sampler can be added to the system to gently aspirate larvae from multi-well plates of many different formats such as 24-, 96-, 384-well and deliver them one at a time to VAST for imaging.  This allows for increased throughput of high content assays and screens.  For more detail and to see a video on VAST go to:


About Union Biometrica, Inc.

Large Particle Flow Cytometry for Gentle Sorting of Model Organisms -- Union Biometrica offers tools for high throughput research of model organism such as early stages of zebrafish, C.elegans, Drosophila embryos and larvae, sea urchin embryos, Xenopus eggs and embryos, Daphnia, various marine larvae and zooplankton. We provide Large Particle Flow Cytometers (COPAS™ and BioSorter®) for objects that are too large / too fragile for traditional cytometers and offer an alternative to manual sorting. These systems analyze and sort objects based on size and fluorescent parameters. Automating this process offers increased speed, sensitivity, quantification, and repeatability of experiments.
