Our vertical glass diffusion cells are classic Franz Cells. Standard orifice diameters are 5mm, 7mm, 9mm, 11.28mm, 15mm, 20mm and 25mm, other diameters are custom. The word “orifice” as it refers to a Franz Cell is the area at the top of the receptor chamber that is exposed to the membrane or device through which transport or permeation is being studied. Corresponding volumes from 5ml to 20ml are standard and are listed under Typical Dimensions. Clamping is achieved through o-ring joints, flat ground (ground o-ring) joints and flat flange joints. We manufacture our own clamps for the most popular Franz Cell models. Our clamps are all stainless steel and are much easier to use than clamps from other suppliers.

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 is a flat flange joint 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 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 7th code only follows the 6th 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 FL is for a female luer joint with stopper Examples #4G-01-00-09-05 describes a clear 9mm jacketed cell with a flat ground (ground o-ring) joint and 5ml receptor volume. #6G-02-01-09-03 describes an amber 9mm unjacketed cell with a flat flange joint and 3ml receptor volume. #4G-03-00-0918-10 describes a clear 9mm jacketed cell with a 18mm diameter spherical joint and 10ml receptor volume. #4G-01-00-11.28-08-VD-0725 describes a clear 11.28mm jacketed cell with a flat ground (ground o-ring) joint and 8ml receptor volume with a volatile donor chamber that has a 7/25 Teflon stopper. #4G-01-01-20-15-VDFT-1420 describes an amber 20mm jacketed cell with a flat ground (ground o-ring) joint and a 15ml receptor volume with a volatile donor chamber that has flow porting and a 14/20 Teflon stopper.
Typical Dimensions
These dimensions are for standard Franz cells. The joint variety does not affect the volume. We can modify most 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. Standard jacketed cells with clamp and stirbar 5mm:5ml volume – .20 square cm area 7mm:5ml volume – .38 square cm area 9mm:5ml volume – .64 square cm area 11.28mm:8ml volume – 1.00 square cm area 15mm:12ml volume – 1.77 square cm area 20mm:15ml volume – 3.14 square cm area 25mm:20ml volume – 4.91 square cm area Standard unjacketed cells with clamp and stirbar 5mm:5ml volume – .20 square cm area 7mm:5ml volume – .38 square cm area 9mm:5ml volume – .64 square cm area 11.28mm:8ml volume – 1.00 square cm area 15mm:12ml volume- 1.77 square cm area 20mm:15ml volume – 3.14 square cm area 25mm:20ml volume – 4.91 square cm area

Nail Adapters
All the pictures show the ABS adapters because its black color gives it better contrast for viewing purposes.
Our Nail Adapters are 28mm wide by 34mm long and were designed to work with 9 & 11.28mm Franz Cells having flat ground or flat flange joints. They have o-rings in the clamping surfaces to prevent leakage. Nail specimens may be secured without or without sealant by four stainless steel screws that hold the assembly together. Nail Adapters are available in three different varieties at this time. Nail Adapters made of plastic can be machined from either ABS or Neoflon. We also have 5mm Nail Adapters available in Type 316 Stainless Steel. The pictures on the right shows all the components of a Nail Adapter. Included are both halves of the adapter, the o-rings for the surfaces adjacent to the Franz Cell components, and the screws that hold the Nail Adapter together.
The upper pictures shows the underside of an assembled Nail Adapter. A piece of Teflon foam is shown between the upper and lower components for clarity. The screws are spaced to not interfere with a 9mm joint. The pictures on the left shows the Adaptors on a Unjacketed and a Jackted cell.
