The virtual scalpel comprises a console, a service trolley and a range of single use hand pieces.

The console houses the control system with LCD display and touchpad.

There is also an integrated cooling circuit, which uses Bürkert fluid control valves to cool the tip of the hand-piece.

The first prototype of the 8711 MFC was supplied to their client in August 2008.

The unit was then tested in Sweden that same month at the company’s R&D facility, in the presence of engineers from Burkert’s Gas segment support team.

Following successful tests, the Burkert factory created a part number for the variant of the 8711, in October 2008.

This was followed by the RoHS statement and request for UR approval, also in November 2008.

The culmination of this activity also occurred in the same month, with a pre-production order to Burkert for an initial batch of ten 8711 units.

In the PlasmaJet application the MEMS technology integrated into 8711 MFC.

This operates according to a thermal principle which has the advantage of delivering the mass flow without any corrections for the required pressure or temperature.

The actual flow rate is detected by a sensor embedded in the wall of a specifically designed bypass channel, into which a small part of the total gas stream is diverted, ensuring laminar flow conditions.
