Self-Contained Ussing Chambers (U9926, U2500)
The U9926 and U2500 Self-Contained Ussing chambers improve on the Classic design by bringing the solution reservoir into the chamber housing. This dramatically reduces the size of the apparatus and increases the ease-of-use of the system.
- Modular design for separate inserts
- No glass circulation reservoirs
- Inserts are quickly exchanged between experiments
- Solution warming is provided by pumping heated water through the chamber halves.
How to order (Please see Item Listing):
1. Select Base Assembly

The Self-Contained Ussing Chamber Systems
The Self-Contained Ussing Chambers systems come in single- and dual-channel models and offer many advantages over the Classic design. The single-channel U9926 and dual-channel U2500 are shown to the right. Both systems make use of inserts to secure and position the tissue or culture cup within the chamber body.
Chamber bodies (single- and dual-chamber models) consist of chamber-halves which clamp around the insert(s). Each chamber-half has four ports that enter into its respective bath compartment: a voltage electrode port, a current electrode port, an air/gas port, and a solution drain port. Solution warming is provided by pumping heated water through each chamber-half and there are no delicate glass heat exchangers to be broken. The dual-chamber U2500 has the additional feature of including four needle valves for adjusting the air/gas mixture into each individual chamber-half.
Inserts can be easily exchanged between experiments. Solutions are removed from the chambers through the drain valves and the halves unclamped from each other. The insert is then simply replaced. Inserts are available to support a variety of tissue sizes and culture cups.
Standard Accessories Supplied with U9926 and U2500
The U9926 (single-channel chamber is supplied with 1 electrode set (consisting of 2 voltage and 2 current electrodes), 12 bridge fittings with adapters; and a tubing/ fitting kit. The U2500 (dual channel) chamber is supplied with two each of the above described accessories. Chamber inserts are ordered separately.
