DVC1000

￭DVC1000 Two-Channel Voltage- Current Clamp

For the study of epithelial tissues
Operate in five modes: voltage clamp, amplify, current clamp, timer, and remote

Features

WPI’s DVC-1000 Two-Channel Voltage/Current Clamp is well-known and widely used for studying epithelial tissues. Each DVC-1000 consists of two separate clamp instruments, one for clamping a control tissue, another for clamping a test tissue. This dual clamp technique lets you monitor changes in membrane permeability as a function of voltage or applied chemical agents. Either clamp unit operates in five modes. Voltage clamp: Clamps the tissue voltage to a given level and displays the current required to maintain that level. Amplify: Shows the potential difference between the two voltage electrodes. Current clamp: Lets you deliver a constant current between the two current electrodes while simultaneously monitoring voltage changes at the tissue. Timer: Functions in either current clamp or voltage clamp experiments, letting you cycle automatically between zero clamp and a preset clamp level. Remote: Allows you to control clamp operation from a computer or other logic level source. Small preamplifiers (included) which mount close to the chamber let you connect to voltage and current electrodes without long cables or agar bridges. DVC-1000 also features a unique ±100 V power supply capable of delivering up to 1 mA of clamp current. Each clamp lets you correct for input offset voltages and fluid resistance error.

Includes:

Two DVC3 preamps and one DVC2 dummy membrane.
