Tip: The mold is optimally used in the 100-800 MPa range. The maximum pressure limit for the mold is 1500 MPa. |
Simple Operation Steps
Prepare your XRF samples efficiently. Standard die sheet size is outer diameter 40mm (for a Φ32mm sample) or Φ40mm sample, with typical pellet thickness of 5-8mm.

Step 1: Assemble the die according to the operation diagram. Place the boric acid-mixed sample powder into the die cavity.

Step 2: Position the assembled die in the center of your laboratory press. Apply the required pressure based on your sample and desired pellet density.

Step 3: After pressing, reconfigure the die for demolding (as per the release diagram). Carefully eject the formed pellet from the die sleeve, typically using the press or a dedicated ejector.

Step 4: Gently retrieve the finished pellet. Your sample is now optimally prepared for XRF analysis.
