A powder sample or sample cup with powder that is placed into the
stainless steel die body of the APEX Die is compressed between the
polished surfaces of an internal plunger and a top stainless steel
polished plate. The top pressing anvil is permanently affixed into the
leadscrew assembly of any Specac Press for use of the APEX Die.
There are two top pressing anvils that are common for use with both
the 40mm and 32mm pellet APEX Dies. One top pressing anvil (P/N
GS26310) is specifically for fitting to the leadscrew assembly of
Specac Autotouch 40T Presses. The other top pressing anvil (P/N
GS26311) is for use with ANY other Specac Press (Manual, Power or
Autotouch variants.)
hen using the APEX Die, it is very important to position the Die
centrally within the pressing sample compartment area of the Press.
To help for a quick and consistent positioning of the APEX Die
centrally in use, a base locator plate is provided with the APEX Die.
This circular locator plate has two dowel pins projecting from its upper
surface and is fitted over the main pressing piston part of a Specac
Press. The APEX Die is simply placed onto the base locator plate and
will be positioned centrally and correctly when the outer sleeve of the
APEX Die engages to touch both dowel pins.
The overall height of both the 32mm and 40mm APEX Dies is 118mm
when the reset button is pressed (Step 1). The maximum amount of a
solid or ground, powdered sample that can be placed into the APEX
die body at the load stage (Step 1), is limited to a depth of 20mm. A
maximum compacted pellet thickness is 7.5mm. hen the APEX Die
is compressed under an applied, steady load (Step 2), the overall
height can be between 92mm to 98mm dependent upon a 1.5 to
7.5mm sample pellet thickness produced within.
The overall outer sleeve diameter of both 32mm and 40mm APEX Dies
is 90mm.
The dimensions and 2.7Kg weight of the APEX Quick Release Dies
are well suited for the preparation of solid pellets/discs for study by X-
Ray Fluorescence (XRF) spectroscopy. Their ease and quickness of
use can assist in the production of a high number of pellet samples per
hour, depending on specific pressing tonnage load cycle regimes.
