New educational material for in vitro-laboratories

This paper presents the potentials to upgrade an educational in vitro laboratory using common devices and a personal computer. In a pilot project we have connected a digital balance with a PC through an RS232 port and in Microsoft's visual basic programming environment we have created the code needed for the interface between the two devices. In addition, we have succeeded in interfacing a common pH-meter connected to a digital burette with a personal computer. The initial results were encouraging, suggesting that we are able to upgrade an educational in vitro laboratory and in the same time to maintain its educative role.
