Laborant Chemstation for Windows 1.21 (Freeware 02.01.03)

KLaborant Chemstation for Linux (Announcement)

(available in english)

LCS is a chemistry and data analysis program. LCS isn't a chemistry education program. It's a program for your daily laboratory work. LCS supports an enormous range of chemical, numerical und statistical functions. I believe, you´ve never seen such a comprehensive chemistry program as FREEWARE.

LCS is a Windows 3.1 program, but it works under Windows95/98, NT4, Windows 2000 and Windows XP, too.

You can use LCS on PowerMacs with the Virtual PC 5.0 emulator. LINUX-, Solaris- and other UNIX-user can use the WABI 2.2 windows emulator for LCS. This is a short overview about the basics of LCS. Additional, LCS includes a huge english ONLINE-help for every subject of LCS.

!!! Runs with SuSE 8.1-Linux and the WINE-Windows emulator without any Windows !!!

Hardware requirement:

min. 486DX33 / 8MB RAM / 640*480 16 colors or higher (386/40 4MB is possible, too)

Graphic resolution: 1024*768/256 colors will be great - min. 3 MB free harddisc space
