Alembic Instruments makes patch clamps amplifiers with 100% Rs Compensation! Our patented Rs CompensatorTM completely eliminates series resistance errors rapidly, easily, and with full stability. Only the Rs CompensatorTM can voltage clamp the largest, fastest ionic currents, under physiologic conditions - currents that are simply out of reach without it. Come see the NEW Alembic VE-3 computer controlled Patch clamp amplifier! Features: 4 channels with integrated data acquisition, true current-clamp, embedded computer with dedicated FPGA for real-time Dynamic Clamp experiments, and more.
