Dodavatel: THERMO H + P LABORTECHNIK

Popis: Compact magnetic stirrers with VARIOMAG drive, hermetically sealed in resistant stainless steel housing (except MINI units which are plastic), making these stirrers ideal for use directly in water baths. MINI stirrers are ideal for integration in analytical instruments, cuvette holders or photometers due to their size, however these plastic units are not designed for use directly in baths. There are units with up to 60 stirring positions in this range, and a choice of three external control units. The TELEMODUL 7 has one power setting, the TELEMODUL 20 C has four power settings: 25%, 50%, 75% and 100% and can store three programmes, the TELEMODUL 40 C features ten different power settings from 10 to 100% and a RS232 interface.
