International Corporation Flexcell® Fluid Shear Systems

Fluid Shear System
Fluid-induced shear stress occurs in every tissue in the body as a result of interstitial fluid movement. Tissue deformation by compression, tension or shear forces results in the movement of interstitial fluid around cells. Fluid movement acts as a transport vehicle for ions, proteins, carbohydrates and other molecules capable of movement within the matrix. As the fluid moves past cell membranes, a shear stress, t, is generated. If one assumes that laminar flow occurs through a parallel-plate flow chamber, fluid-induced shear stress values can be determined with the following formula: t = 6uQ/bh², where t is the shear stress in dyne/cm², u is the viscosity of the fluid in dynes/cm², Q is the flow rate in ml/s, b is the width of the flow channel in cm, and h is the height of the flow channel in cm.

The Streamer® is a parallel-plate flow system that is used to apply fluid-induced shear stress to cells grown in a monolayer. The system includes a six-chamber laminar flow device designed to hold 75 x 25 x 1 mm Culture Slips®. The Streamer® system can be used to apply laminar, pulsatile*, or oscillating* flow to cell in monolayer culture (Figure 3) and uses a computer-controlled peristaltic pump to regulate shear stress from 0-35 dynes/cm².

*When used in conjunction with the Osci-Flow® Flow Controller.

Flexcell® Osci-Flow® Flow Controller
 

A flow control system that gives the user the ability to regulate the frequency of oscillation or pulsatile patterns as well as shear stress levels applied to cells through StreamSoft™ and NI-DAQ software.

• Reverses fluid flow instantaneously.
• Reduces wear and tear on pumps and motors.
• Adapts to other perfusion systems.

The Flexcell® FlexFlow™ Shear Stress Device is a parallel plate laminar flow device designed to apply fluid shear stress and/or cyclic strain to cells in culture while providing a means for viewing cell activity under a microscope in real time. Like the StageFlexer®, the FlexFlow™ fits on the stage of a standard upright microscope.

For fluid flow on the micro and nanofluidic levels, Flexcell has the HiQ Flowmate Fluid Control System. The HiQ Flowmate® unit is a dual syringe pump that utilizes five separate modules: constant, continuous, ramped, oscillatory, and pulsatile flow to represent a variety of applications. In addition to applying fluid shear stress to cells in culture, this device can also be used for diluting, dispensing, & injecting; animal drug infusion and fluid withdrawal; mixing & proportioning fluids, among other applications.

FlexFlow™The FlexFlow™ is a parallel plate laminar flow device designed to apply fluid shear stress and/or cyclic strain to cells in culture while providing a means for viewing cell activity under a microscope in real time. The FlexFlow™ fits on the stage of a standard upright microscope.

Osci‐Flow®The Osci-Flow®

Osci‐Flow®The Osci-Flow® is a software-controlled valve-operated device designed to provide oscillatory or start-stop flow patterns to cells cultured in the Streamer®, FlexFlow™ or other perfusion devices. The Osci-Flow® device is able to regulate flow both in an oscillatory (flow reversal) manner and in a pulsatile (square wave) mode, where the flow is stopped and then restarted after a designated period of time. The StreamSoft™ software allows the user to regulate frequency of oscillation or pulsatile patterns, as well as shear stress levels applied to cells.

Why fluid shear stress

Fluid-induced shear stress occurs in every tissue in the body as a result of interstitial fluid movement. Tissue deformation by compression, tension or shear forces results in the movement of interstitial fluid around cells. Fluid movement acts as a transport vehicle for ions, proteins, carbohydrates and other molecules capable of movement within the matrix. As the fluid moves past cell membranes, a shear stress, τ, is generated. Applying stresses to cells in culture simulates the in vivo environment causing dramatic morphologic and biochemical responses.

Culture Slips® Microscope Slides and Coverslips

 

• Culture Slips® are available in two sizes: 75 mm x 25 mm x 1.0 mm (for Streamer® or FlexFlow™), 75 mm x 24 mm x 0.2 mm (for FlexFlow™ only).
• The 25 mm x 75 mm x 1.0 mm Culture Slips® are rimmed with a 1.0 mm wide Teflon® border to help limit cell culture growth to the portion of the slip exposed to fluid flow.
• Available with covalently bound extra cellular matrix surfaces such as Collagen Type I, Elastin, Pronectin®, Laminin, Amino, as well as untreated.

StageFlexer® Membranes for the FlexFlow™

 

Flexible growth surfaces that are individually packaged free membranes for the StageFlexer® or FlexFlow™ dynamic culture products.

• Applications consistent with BioFlex® culture plates.
• Membrane is clear for direct viewing of cells.
• Membranes are in a closed SpillGuard® culture dish to maintain sterility even after outer packaging is opened.
