Spex

Founded in 1954 in the United States, Spex® (now part of Spex SamplePrep) has established a global reputation as a premier innovator in the design and manufacture of high-performance sample preparation equipment. Known for rugged reliability and precision engineering, their systems are designed to handle even the most challenging materials, from rock and mineral specimens to forensic tissues. As the authorised Australian partner, we provide local laboratories and research institutions with direct access to these advanced tools, which are fundamental to the Laboratory sector across Australia and New Zealand.

Spex engineering focuses on delivering sample homogeneity and analytical accuracy through high-energy milling and automated grinding solutions. Their portfolio is built to support demanding analytical workflows in forensics, geology, and pharmaceutical research, ensuring reproducible results every time. We back these advanced technologies with factory-trained engineers and local technical guidance to help your facility maintain the highest standards of preparation efficiency and durability.

Technical Applications for Spex in Australia

In Australian research and industrial settings, the ability to rapidly homogenise complex samples is critical for downstream analytical success. The range of Laboratory and scientific equipment available from this brand includes the Spex 2030 GenoGrinder, an automated high-throughput homogenizer that replicates a vigorous vertical grinding motion for fast cell lysis and tissue disruption. This system is particularly valuable for labs requiring unattended, large-scale sample processing in fields such as molecular biology and genetics.

For X-ray fluorescence (XRF) and elemental analysis, maintaining a contamination-free sample window is essential for data integrity. Our inventory includes a variety of high-purity films, such as the Spex Mylar Window Film (0.25 mil) and the ultra-thin Spex 3516 Mylar Window Film Sheets for maximum transmission. For specific chemical resistance needs, technicians can choose the Spex 3520 Polypropylene Window Film or the high-purity Spex 3525 Ultralene Window Film, which offers an excellent balance between strength and X-ray transmission for light-element analysis. By combining these precision consumables with robust grinding mills, we help Australian laboratories achieve consistent, high-fidelity results across all sample types.

Frequently Asked Questions

What is the benefit of using a Geno/Grinder for tissue homogenization?
The Geno/Grinder utilizes a unique vertical pulverizing motion that ensures consistent sample processing across every well of a titer plate. This motion is far more efficient than traditional horizontal shakers, resulting in complete cell lysis and homogenization in under two minutes.

Why would I need a cryogenic Freezer/Mill instead of a standard ball mill?
Cryogenic milling is essential for samples that are difficult to grind at room temperature, such as polymers, rubber, or certain biological tissues. By cooling the sample with liquid nitrogen, the material becomes brittle and can be pulverized without melting or losing volatile components.

Which XRF window film should I choose for light-element analysis?
Ultralene window film (0.16 mil) is typically preferred for light-element analysis because its thinness allows for a greater degree of X-ray transmission while maintaining the strength and chemical resistivity needed to contain liquid samples.

Are Spex mills suitable for rock and mineral preparation in geology?
Yes, the ShatterBox ring and puck mill is specifically designed for rapidly pulverising brittle materials like ores, rocks, and cement into fine powders. It is a staple in Australian geology and mining laboratories for preparing samples for XRF or XRD analysis.

Can the Spex 2030 GenoGrinder be integrated into an automated robotic workflow?
Absolutely. The 2030 model is designed with a specific footprint and control interface that allows for seamless integration with most robotic systems, enabling high-throughput labs to process samples unattended for 24/7 operation.

Does John Morris Group provide local maintenance for Spex equipment?
We have a dedicated team of factory-trained service engineers across Australia and New Zealand who provide installation, preventative maintenance, and repair services for all Spex SamplePrep instruments. This local support ensures your laboratory avoids downtime and maintains technical precision.
