The ability to rapidly apply reagents to cells and tissue is an important issue in laboratories today. The DAD-8VC is a voltage controlled superfusion drug application device, designed for drug application to single cells, groups of cells, or cell chambers. The system is equipped with 8 reservoirs, 8 magnetic valves for 8 drug channels and one flush channel. The magnetic valves can be controlled via PULSE or TIDA, using one DA output channel of the EPC 9, ITC-16, or ITC-18. The valve number is encoded by analog voltage. For connection to the EPC 9/ Double/ Triple and ITC-16, ITC-18. Other versions on request.

The 8 tubes converge in a micromanifold with polyamide-coated quartz capillaries of inner diameters of 100 µm (flush tube 200 µm). The quartz capillaries flow together into a terminal tube of 100 µm ID with a dead space of <1 µl. The micromanifold is within a silicone sleeve to be mounted in any micromanipulator.

optional:

• Solenoid valves with min. 1 ms opening time (24 - 9 V)
• Micromanifold with tubes of 200 µm or 300 µm ID
• custom variations of tube number and size
• Pressure regulator PR-10
• Other versions as DAD-8 (with laptop and software) on request.

The DAD-12 is the programmable equivalent to the DAD-8VC. It is equipped with its own laptop leaving the control of the valves and valve sequence independent of the data acquisition computer.
