SPCALC Electronic Solubility Handbook, Database and Calculator
If you are a working scientist, engineer, student, or formulator or you simply need to find optimum solvents or solvent mixtures for any application, try SPCALC. SPCALC can find solvents in its database of physical properties for 1200 solvents meeting single or multiple criteria for any solute, sort the results in any of 8 ways, predict solute solubility, or calculate an optimum solvent mixture from basic physical principles. Full, context-sensitive, pop-up help, extensive documentation, quick-tour tutorial, fully-customizable, macros, Windows/OS2 multitasking support, and much more! Based on the original Hildebrand-Scott solubility parameter concept, as extended by Hoy and Small, SPCALC's calculation methods are founded on accepted, fundamental physical principles. SPCALC was written by Dr. John M. Zeigler for use in his own research, formulation and polymer compatibility work. Its over 100 page manual includes a quick tour tutorial, full use instructions and suggestions, support information and a detailed scientific appendix for those who would like to understand the scientific basis for the program. SPCALC has been newly updated in 2007 with a Windows install program and an updated manual, available to registered owners in printable PDF format.
SPCALC's default solvent database file contains physical property data (molecular weight, density, solubility parameter, melting point, boiling point, refractive index, and dielectric constant) for nearly 1200 organic and inorganic solvents. The physical property data have been derived from a variety of standard reference works. Every effort has been made to assure the accuracy of these data and several corrections of incorrect data in these works have been made.
A trial version of SPCALC, with limited functionality and a reduced database of 200 common solvents, can be downloaded free from the link below. A full version, with support, over 100 page manual, full functionality, and the full printable 1200 solvent database is available for $29 US, plus $5 S/H, or $29 sent by e-mail from this site. SPCALC System Requirements SPCALC, Version 5.0.1, requires an IBM PC compatible computer with 1.5 Mb free hard disk space, 384K RAM of free conventional memory, and any video card and monitor (color VGA recommended). The program will run under DOS, v. 2.11 or later, any version of 16 or 32-bit Windows (including Vista®), 64-bit Windows with a DOS emulator, and OS/2. Macintosh users can run it only if they have DOS emulator software running on their machines or if DOS is supported natively. See our support page for more information on DOS emulator software and SPCALC. Download Trial Version

SPCALC runs on all PC operating systems, including
32-bit Windows Vista® and 64-bit Vista with a DOS
emulator.
As a result of extensive code optimization, it will run rapidly on virtually any
PC-compatible. An earlier trial version of SPCALC, lacking the Windows
installation program and PDF documentation, has been included in a number of
compendia of scientific programs and has been rated 4 stars by Ziff-Davis
Interactive. 
A full version of SPCALC, with support, over 100 page manual in
printable PDF format (see reduced size pages at left), full functionality, and the full 1200 solvent database is available for $29 US, plus $5 S/H on diskette or CD-ROM, or $29 US (no S/H) sent by e-mail or
downloaded upon receipt of your check or money order. See our
