The RE1600 Transcellular Electrical Resistance Meter is a compact instrument specifically designed for measuring transepithelial/transendothelial electrical resistance (TEER) and potential difference (PD), serving as a domestic alternative to imported counterparts.
Using a small, hands-free chopstick-style electrode, the RE1600 conveniently enables rapid measurements of epithelial or endothelial cell tissues in Transwell inserts.
With specialized electrodes, the RE1600 can also measure native or cultured epithelial tissues mounted in Ussing chambers.
【Key Features】
1. Utilizes AC pulse technology to prevent metal deposition on electrodes and avoid adverse effects of continuous DC current on tissues. Resistance readings are unaffected by membrane capacitance and voltage.
2. Employs AC pulse technology to prevent metal deposition on electrodes and avoid adverse effects of continuous DC current on tissues. Resistance readings are unaffected by membrane capacitance and voltage.
3. Dual-leg, four-core electrode structure: Insert each leg into the inner and outer compartments of the culture cup, select the appropriate range, and real-time measurement values are displayed.
4. Hands-free measurement electrode minimizes data fluctuations caused by handling, ensuring more stable readings and accurate results.
5. Built-in 1K ohm standard resistor allows for隨時(shí) verification of the instrument's measurement circuit functionality.
6. Multiple electrode specifications available, compatible with 6 to 96-well plates.
