Typical microscope perfusion chamber designs represent a compromise between optical considerations, flow requirements, and shear stress on the cells; optical constraints imposed by DIC microscopy are often favored at the expense of flow characteristics necessary for rapid exchange of media. We have developed a perfusion chamber which enables fast, reproducible medium exchange under controlled shear conditions. Our chamber is best suited for high numerical aperture epifluorescence microscopy and phase contrast microscopy with a long working distance condenser, but it cannot be used for DIC microscopy. Complete exchange of the medium over a 12 mm diameter area of the cover slip can be accomplished in several seconds, and the medium over a typical microscope field can be exchanged in about 1 second, with shear rates that will not damage adherent cells (0.1 - 3.0 dyn/cm2). The combination of this chamber with the Flow Injection technique, which is widely used in analytical chemistry, provides a highly versatile tool for microscopy. Experiments requiring complex perfusion profiles may be run under computer control with better than 1% reproducibility of the concentration profile from run to run. This technique is a significant improvement for cell physiological experiments requiring rapid, precise environmental control on the microscope stage.

It exploits radial flow-through a narrow ring-shaped gap (20-50% of the particle diameter) to retain suspended particles within a well-defined detection region; trapped particles can be removed instantaneously by flow reversal. The cell was characterized by analysis of various beads (e.g., Polysorb MP1 and Sephadex) stained with dyes or fluorescent reagents and suspended in suitable buffers, using a sequential injection system with a flow-rate of 2.5 ml/min, a reverse flow-rate of 10 ml/min, a carrier solution of 0.01 M sodium borate buffer and a microscope system equipped with an epifluorescence attachment (details given). Cytodex 3 beads covered by adherent, stained BHK cells were also used with a carrier solution of HEPES buffer. The cell should prove useful for automated immunoassays and monitoring the pre-concentration of analytes on sorbents. A new flow cell design for spectroscopic measurements of suspensions, the jet ring cell, is introduced. This cell exploits radial flow-through a narrow ring-shaped gap to retain suspended particles within the detection region. This ring constitutes a detection volume of well- defined area from which the trapped particles can be instantaneously removed at will. The bed of particles thus forms a renewable surface, which can be probed by reflectance, fluorescence, or chemiluminescence using a microscope or optical fiber.

Liquid/liquid interfaces were formed parallel to the side wall of the microchannels, because the surface tension and friction force are stronger than the force of gravity. A water/ethylacetate/water interface was formed in a 70 µm-wide and 30 µm-deep channel. The interface was observed to be quite stable and to be maintained for a distance of more than 18 cm. As an example of a multilayer flow application, we demonstrated the liquid/liquid extraction of Co-dimethylaminophenol complex in a microchannel.
