The paper presents the 1st Slovak e-laboratory of nature sciences with real remote experiments and the data transfer. The laboratory uses a unified approach, as the hardware used is the ISES (Internet School Experimental System) and its modules, while the software for the server-client connection is based on internet pages and Java applets. E-laboratory is free available on the page http://kf.truni.sk/remotelab and in the present time it consists of five experiments from physics: Environmental monitoring, Simple pendulum, Free fall, Faraday’s law, Energy transfer in oscillators, and the first e-experiment from chemistry, Electrochemical cell.
