Whitehouse Scientific launches new Opaque Microspheres

Whitehouse Scientific, one of the most widely recognised and respected manufacturers of particle size calibration standards using glass microspheres, has added basalt microspheres to its range.

The transparency of standard glass microspheres presents problems for some particle sizing systems and technologies. Being opaque, the new basalt standards provide an alternative and long term solution.

There are 20 individual narrow distribution grades each with excellent sphericity, ranging in size from 50 microns up to 2 millimetres. The calibration standards are supplied in convenient 100g lots.

Available for immediate purchase, the new basalt microspheres are designed for use in both lower grade and initial research applications. Should additional classification be required, this can be carried out on request to provide a higher grade certified standard with NIST traceability.
