This manual hydraulic press for a 25-t pressure load is a Retsch laboratory
instrument and is suitable for, among other things, preparing samples for X-ray
fluorescence analysis and the potassium bromide pellet technique.
Safety discs made of polycarbonate and the ease in handling this press make it
very user-friendly.
The pressure gauge has a 0-40-t scale with increments of 0.5 tonnes. The
available working range amounts to a max. 147 mm.
(Spacing between the lower supporting space and the pressing face of the
threaded spindle)
The die tool can be evacuated with an appropriate pump and vacuum hoses. To
facilitate this, the die tool has a hose connection nipple for hoses with a nominal
width of 8 mm.
NOTE
This press is suitable only for pressing tablets in sizes of 1¼ inch (32 mm) and 40
mm and ejecting them out of the die tool. It accommodates die tools for tablets in
the sizes 1¼ inch (32 mm) and 40 mm.
