Union Biometrica to exhibit at the Heart of Europe Zebrafish Meeting in Warsaw, Poland

Join us before the meeting for a workshop and demonstration of our instruments developed specifically for zebrafish screening:

Topic: Tools for High Throughput / High Content Zebrafish Screening

Date: Tuesday, September 16, 2014

Time: 9am-5pm

Location: International Institute of Molecular and Cell Biology: Lecture Hall 012 (ground floor)


At the meeting you can learn more about our technologies by attending the following customer presentation:

     Herman P. Spaink, Leiden University, Leiden, The Netherlands
    At the crossroads of immunity and metabolism: novel insights from zebrafish screening technologies.

    IX session - Emerging technologies, Friday, September 19, 2014 2:15 p.m. - 2:45 p.m.


The VAST BioImager system, automates the tedious step of positioning 2-7 dpf zebrafish larvae for imaging. The system gently 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. Additionally the VAST can be mounted on a high resolution upright microscope for high content bright field or fluorescent imaging at the cellular level.  An LP Sampler module 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:

The BioSorter flow cytometer is designed to provide the flexibility for working with samples ranging in sizes from 1 to 1500 microns.  These samples can be analyzed and dispensed intact because of the low sample pressures, low shear forces and the gentle air sorting mechanism.  An LP Sampler (Large Particle auto-Sampler) can be added to automatically load samples from multiwell plates to the BioSorter for analysis and re-sorting.

About Union Biometrica, Inc.

In addition to the VAST BioImager system, Union Biometrica offers Large Particle Flow Cytometers for high throughput research of model organisms (early stages of zebrafish, C.elegans, Drosophila embryos and larvae, sea urchin embryos, Xenopus eggs and embryos, Daphnia, various marine larvae and zooplankton), plus bead based assays, stem cells and cell clusters (iPS cells and embryoid bodies as well as other types of large cells / cell clusters). The COPAS™ and BioSorter Large Particle Flow Cytometers are designed 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. 

Peer reviewed journal papers referencing our COPAS and BioSorter instruments can be viewed using the links below.
