2. Description of the Product
Pentamix
™
2, manufactured by 3M ESPE, is an automatic mixing unit for
processing of Penta impression materials. Penta impression materials,
manufactured by 3M ESPE, were specifically designed for this device
and are supplied in specialized foil bags. Only this form of packaging
permits the use in the Pentamix device. Each Penta foil bag is sealed
with a PentaMatic sealing cap. The external geometry of the sealing
cap ensures proper positioning on the cartridge. After the Pentamix
device is started up, a special internal device opens the foil bag once
sufficient pressure is established by the plunger. The connection pieces
located on the PentaMatic sealing caps serve for proper attachment
of the mixing tip.
The cartridges, labeled like the product, and the PentaMatic sealing
caps are the components of a mechanically sound unit for processing of
pastes in the Pentamix device that allows a change of products without
intermediate cleaning of the device and no loss of paste.
The Pentamix is supplied as a table-top unit, but can be converted into a
wall-mounted unit with the respective wall mounting brackets, which can
be ordered from 3M ESPE (Art. No. 077600).
