Precision Microspheres
Precision Microspheres (iSpheres(TM)) Manufactuered by XL Sci-Tech Inc.
i Spheres™ have the highest sphericity (>95%) and quality in
the industry (>90% in range, minimal over Max).  Mono-sized (i.
e. mono-dispersed) spheres are even tighter in size (tightest in
the industry).  XL Sci-Tech has a proprietary and advanced ON-
DEMAND microspheres production facility capable of large
volume and custom sphere properties (color, density,
tracers/isotopes, diagnostic, fluorescent, …).

i Spheres™ Density Range from 1.3 to 15.0 grams/cc
Density is a function of matrix material and micro/nano structure of
microspheres.  i Spheres™ are made of glass, ceramic, polymer, metal/alloy or
hybrid/composite.  Let us discuss the right i Spheres™ for your application.
i Spheres™ Colors and Surface Modifications
Colors and surface modifications or functionalizations are discussed as part of
Functional Microspheres product line.  Contact us for any questions.
i Spheres™ (aka IsoSpheres™)
Size codes for standard U.S sieve sizes are shown in table to the right.  For
applications that require extremely tight tolerance and non-standard sieve sizes,
monodisperse i Spheres™ are available.  The tolerance can be specified by
customer in microns (e.g. 90±5um or 85-95um or size code 085095)
