GSA L87

The heart of the Linseis GSA L87 series is our unique magnetic suspension balance, which is characterized by a reaction chamber for very aggressive gases, as the weighing chamber is decoupled in this variant.
A large selection of reactors is available in a temperature range from
-170 °C to 1800 °C and a pressure range from ultra-high vacuum to 300 bar.
