El Baidouri Shield

Developed in collaboration with Dr. Fouad El Baidouri, a research associate at Harvard School of Public Health’s Neafsey Lab, the El Baidouri Shield offered by Analytical Sales & Services, Inc. is an anti-contamination barrier which can be used when performing highly sensitive work, such as infectious disease research.

The shield solves the issue of micro punch-card particles (which may be ejected during operation) potentially falling into adjacent wells, resulting in undesirable cross-contamination. A semi-clear gasket washer creates a seal around the glass pipette and prevents the micro-particles from entering neighboring wells.

The shield attaches securely to the existing DBS punch unit. Installation is quick and easy via the provided set-up guide. Cleaning the shield is simple, as enough space is provided for users to remove and dispose of the particles that are caught by the shield.
