A PermeGear flow type Franz cell is a standard Franz cell with additional porting for circulating receptor medium continuously through the receptor chamber of the cell. As with static Franz cells, flow porting may also be added to the donor compartment if needed. The phrases “flow thru”, “flow cell”, and “flow type” are used interchangeably and refer to flow only through the receptor compartment, and do not signify anything with respect to the heating jacket.
Ordering Information
Part numbers are generally made up of 2-character codes separated by hyphens.
- 1st code is cell type: 4G is for a jacketed cell, 6G is for an unjacketed cell
- 2nd code is joint type:
- 00 is an o-ring joint
- 01 is a flat ground (ground o-ring) joint
- 02 flat flange joints are not available on flow cells
- 03 is a spherical joint generally used for corneal work
- 3rd code is glass type: 00 is for clear glass, 01 is for amberized glass
- 4th code is orifice diameter in millimeters, 05 through 25
- 5th code is receptor volume in ml, 03 through 20
- 6th code is FT indicating a flow type cell
- 7th code is 01 through 04 indicating the configuration of the flow ports according to the variety of flow cell desired. The four varieties are pictured in the gallery at the left side of this page. Type 3 is the most commonly ordered.
- 8th code is optional and indicates:
- VD is for a volatile donor compartment with ground glass joint and Teflon stopper
- VDFT is for a flow through volatile donor compartment with ground glass joint and Teflon stopper
- VDOC is for an completely occluded volatile donor compartment
- VDOF is for flow thru volatile donor compartment without ground glass joint and Teflon stopper
- 9th code only follows the 8th VD or VDFT codes if a stoppered donor is required:
- 0725 is for a 7/25 ground glass joint with teflon stopper
- 1420 is for a 14/20 ground glass joint with teflon stopper
Examples
- #4G-01-00-09-05 is for a 9mm jacketed cell with a flat ground (ground o-ring) joint and clear glass with a 5ml receptor volume
- #6G-02-01-05-05 is for a 5mm unjacketed cell with a flat flange joint and amberized glass with a 5ml receptor volume
Typical Dimensions
These dimensions are for standard flow type Franz Cells, the joint variety does not affect the volume. We can modify most any of these parameters within the practical limits of blown glass. Do not hesitate to inquire if your studies need something other than what is listed here. The term “cell” for sales and pricing purposes includes the two glass components, the clamp for the joint, and the stirbar.
