Microfluidic Flow Chamber for Bacteria

The B-Series microfluidic plates keep bacteria cells in a single focal plane, allowing you to follow and induce cell events during high magnification imaging over many generations.
B04 Microfluidic Plate   e. coli
Features and Benefits:

• Elastic trap sites holds cells in single focal plane for 16+ hours
• 4 independent chambers under a single imaging window
• Laminar flow switching between 5 inlet solutions
• 170 um thick optical glass bottom for high quality imaging

Plate Types:
B04A for 0.7-1.0 um Cells, 4 Chambers

B04A Application Note

For Updated Applications, please click here to visit the EMD Millipore site.

The B04 plates utilize a microfabricated silicone ceiling with a height similar to bacteria cells to restrict their growth in a single focal plane and maintain x,y position over time. Each chamber contains 6 tapered trap heights to maximize loading efficiency of various cell sizes. The B04A plate has heights of 0.7, 0.9, 1.1, 2.0, 3.0 and 4.0 um. (See Product Sheet for more detail.)

Bacteria Trapping   Single Focal Plane Bacteria 

Continuous perfusion of culture medium to the cells ensures a suitable growth environment for long term experiments. Typical experiments run for 4-16 hours on the microscope stage, enabling single cell tracking for over 10 doublings. The six inlets to each chamber allow solution switching experiments during time lapsed imaging. The highly laminar flow results in a rapid and complete solution change in under a minute.
