What it is

Transportable Sample Press

What it does

Used to generate a pressed puck from sample powder for use in XRF and other sensor analyses such as VNIR and LIBS

Key benefits:

  • Better quality data – densely packed uniform sample puck, and improves light element analysis
  • reduces potential for signal attenuation due to film coating
  • Lower cost – decreased cost of consumables (sample cups no longer required – savings $150 per day)
  • Increased productivity – reduced number of steps with simplified process
  • Increased safety – uses only high quality, fit for purpose products, light and easy to transport


On-site for greenfields, brownfields and operating mines where consistent workflows and high throughput are required


Q: How heavy is it – can I transport it?
The REFLEX SP30M is less than 30kg in weight and comes in 2 robust and easy to transport pelican cases.
Q: Does the sample press produce a representative sample?
No. The sample press does not reduce the need to use representative sampling methods to sub-sample the powder
Q: Can any powder be used to make a puck?
For most geological materials it should be fine to make a puck without binder, however very qtz rich materials (i.e. qtz blank) will not fuse properly. In this case the user can either use an XRF cup OR source a binder such as wax or boric acid depending on how much problem material they have
Q: Is the sample press safe?
The sample press does pressurise with hydraulics and does exert large forces on the sample, however the system is engineered with specific custom materials and designs to maximum safety with a large factor of safety built into the SOP. As long as the user follows are guidelines there is very little chance for injury. The materials and hydraulics have all been pressure tested and the sample press has been through Solidworks simulation to test for failure and repeated cycling. These reports can be made available.
