The Katanax® X-300 fluxer is a key part of our new offering in next-generation electric fusion, providing exceptional flexibility for outstanding ease of use and unparalled results.

This multi-sample fluxer is available in 1, 2 or 3 positions, and can later be expanded, thus adapting to the needs of today’s modern laboratories. Here is what customer Owens Corning had to say about its pre-release trial:



The X-300: Features

Special features

  • Expandability
    • Available pre-configured as a 1, 2 or 3 position unit
    • Upgradeable by customers in their own labs
    • Adapts laboratories' changing needs
  • Innovative heating elements
    • Impervious to flux and other chemical projections
    • Robust and non-brittle (instrument can be moved without element damage)
    • Cartridge type for easy replacement
    • Can be changed individually, with minimal interruption
  • Advanced furnace
    • Dynamic Temperature Profile (DTP) to ensure uniform temperature (patent pending)
    • Individual element automatic power compensation (patent pending)
    • Fast heat-up (<15 minutes)
    • Strict use of ceramic eliminates metal contamination
  • Other
    • Industrial PLC interface (does not depend on Windows updates)
    • Requires no external supplies (no power supply box, no cooling fluids)
    • Single-phase power (no need for 3-phase)
    • Tiltable interface screen for various user heights
    • Ambient status light (red when processing, blue when completed)


  • Built with the most demanding lab in mind
  • Heating elements impervious to flux and chemical projections
  • Robust, all-ceramic platinumware holders
  • Industrial-grade motors and electronics
  • Shares several components with the heavy-duty X-600


  • Simultaneous processing of up to three (3) samples
  • Can prepare glass disks (beads) for XRF, or solutions for ICP, including preparations in peroxide or pyrosulfate
  • Throughput of up to 15 samples/hour
  • Fast initial heat-up time of under 15 minutes
  • Productivity is improved by a user-adjustable holding temperature. Therefore, the temperature between fusions can be maintained to minimize initial ramping time


  • No gases used, so no post-combustion toxic products released
  • Minimal heat dissipation; only a standard vent hood is required
  • Integrated, auto-locking protection shield with safety glass viewport


  • Extra-precise temperature control achieved by Dynamic Temperature Profiling (DTP) and automatic individual element power compensation (patents pending).
  • Entirely automated, cold-to-cold
  • Fully reproducible fusion methods
  • Outstanding reproducibility: all crucibles and molds are at the same temperature
  • Real-time temperature display
  • Optimum pouring conditions, since the molds are in the furnace with the crucibles


  • Makes glass disks for XRF
  • Can also make solutions (including peroxide or pyrosulfate fusions without modification)
    • Optional variable-speed embedded solutions stirrer available
    • Prepares up to three (3) solutions for ICP or AA
    • Switching from disk to solution mode is quick and easy
  • Ready to fuse with built-in methods for oxides, minerals, metals, alloys, sulfides, fluorides and more
  • Can perform solid or liquid oxidations
  • Fully customizable fusion methods


  • An expandable, intelligent, advanced furnace
  • Easy installation
  • Intuitive graphical interface with multiple languages
  • Easy icon touch-screen navigation
  • Virtually maintenance-free; easy component access


The X-300 fluxer:
Technical specifications

Installation is fairly simple, just like another lab furnace:

  1. Run a 220 VAC wire from the 15A breaker box to the installation site. (You might well have such an outlet already installed.)
  2. Connect instrument to this standard wall outlet and turn on.
  3. Enjoy !

What is in the X-300 box

  • 1 fluxer (X-300 main unit)
  • 1 tool kit (hex keys, spare fuses...)
  • 1 instruction manual
  • 1 USB memory stick (for firmware upgrades and program backups)
