Sample Preparation Surface Grinder
SPECTRAL 250 is a table-top portable surface grinder for the preparation of steel samples for spectroscopy. It’s compact design with vibration free operation makes it a practical instrument to work with. Low noise and dust generation levels as well as standard outlet for dust exhauster are additional advantages.
250 mm grinding disc is dynamically balanced for smooth running. Grinding paper is sucked to the grinding disc which does not require any glue. Papers with 60 grit can be used to obtain the desired surface quality. The grinding disc is covered halfway by a lid, allowing grinding only in a segment. A safety switch guarantees automatic switch off when the lid is opened.
SPECTRAL 350 is used to achieve precision flat surfaces of iron and steel samples for spectroscopic analysis. The robust and vibration-free construction has been designed for continuous operation at high sample throughput.
SPECTRAL 350 Series of instruments are available as single disc and dual disc units with 350mm wheel size which is dynamically balanced for smooth running. Due to its special design, grinding paper is sucked to the grinding disc which does not require any glue.
The SPECTRAL 350 is purpose-built to produce precision-flat surfaces on iron and steel samples for spectroscopic analysis. Has a dynamically balanced 350 mm grinding wheel, it delivers smooth, stable operation with dual-speed capability at 1,400 / 2,800 rpm and independent grinding discs as standard.
A powerful integrated aspiration system uses vacuum suction to hold abrasive paper firmly across its full width — no adhesives or mechanical fixings required. This not only makes paper changes quick and effortless, but ensures the full surface area of the abrasive is always in use. A built-in dedusting system with spark trap keeps the working environment clean, with minimal noise and dust generation throughout operation.
Safety and ease of use are central to the SPECTRAL 350's design. The unit is fully enclosed except at the operating segment, maximising operator protection, while compatibility with both mechanical and magnetic sample holders adds versatility. The SPECTRAL 350-S further enhances performance with two independent 2.2 kW drive motors, making it a robust and reliable solution for all spectroscopic sample preparation needs.
