MVCS / MVCC
Iontophoretic Drug Ejection

MVCC-M-45   Standard system
   Balance module for up to four channels without capacity compensation

MVCS-M-45   
   Single channel system with capacity compensation, elecctrode resistance test
   and a headstage

MVCS EPMS modules have the same specification as the 19" stand-alone devices except that they do not have a built-in balance channel. But a separate module (MVCC) can be used to balance the ejection current from up to four ejection modules.

IMPORTANT: The EPMS-H-07 housing is required to operate these modules!!!

Standard voltage range is ±45 V. Other voltage ranges (±15 V, ±150 V, ±225 V) are available on request.  

Options

OVERLOAD: starting to light up at ±10 V

OUTPUT: impedance 250 Ohms, max ±12 V, short circuit protected

DIMENSIONS: front panel 12 HP (60.6 mm) x 3U (128,5 mm), 175 mm deep.

PDES 
Pneumatic Drug Ejection

HV-TR150
Tracer Injection

BRAM(1) and HV-TR150(2) headstages with electrode holder(3)

PDES modules for the EPMS system are available in digital and analog versions with one channel. They can be operated using an internal or an external valve. Maximum pressure is 4 bar / 58 psi. For digital timing an additional module, TMR-01, is required.

PDES systems are also available as 19" stand-alone devices.

The HV-TR150 is a high voltage amplifier designed to inject dyes into cells iontophoretically. It can be used in combination with an amplifier module or independently as a iontophoresis system.

The HV-TR150 can deliver max. 1500 nA into 100 MOhm and can be operated continuously or gated by a TTL signal. The injection current can be set either by a built-in potentiometer or by a data acquisition system.
A toggle switch allows convenient switching between recording and injection, when operated in combination with an amplifier module using the same electrode. This switch can also be operated with a TTL signal. Two LEDs at the front panel indicate whether the amplifier or the HV-TR150 is connected to the electrode. A red LED at the headstage indicates additionally that the HV-TR150 is connected to the electrode.
A digital display shows the amplitude of the injection current.

IMPORTANT: The EPMS-H-07 housing is required to operate this module!!!
