TURBO TEC systems are accurate and extremely fast voltage and current clamp amplifiers for studying large membrane currents. They are based on the standard two electrode approach. TEC systems are ideal for recordings from oocytes as well as for recording from other excitable tissues with relatively large membrane currents such as vertebrate and invertebrate neurons and muscle cells. A significant improvement over other two electrode clamp amplifiers is that the TEC systems fully compensate the current injecting microelectrode and need NO virtual ground for recording membrane currents. TEC systems can be operated with a reduced bandwidth of 10Hz to allow simultaneous single-channel recordings with patch-clamp amplifiers. All amplifiers are equipped with two headstages. The standard output voltage is ±150V. All systems include four modes of operation, many automatic functions, protection circuits, versatile I/O signal conditioning units, and digitally controlled operation.

The TEC-05X is a universal two electrode clamp system for recordings muscle cells and large neurons, but also from Xenopus oocytes. It allows the use of high resistance electrodes.

The TEC-10CX is npi's most sophisticated two-electrode amplifier for Xenopus oocytes. Multiple elements for controlling parameters of voltage clamp and a transient compensation unit allow experiments to take place with maximum clamp speed and accuracy.

All TEC systems can be completed with a Series Resistance Measurement Instrument for measuring series resistance in two electrode voltage clamp recordings.
