Zero-field furnaces
Two Pyrox furnaces used for thermal demagnetization, located in the magnetic shielded room.
Capacity of 24 samples each.
Field in the cooling part: 2 to 5 nT.
Mobile medium capacity paleointensity furnace
Pyrox furnace used for palaeointensity experiments.
Up to 48 standard size samples.
Heating and cooling in air or under Argon flow continuously passing over the samples and controlled by a bubbler.
Furnace kept at the right temperature and positioned over the tube containing the samples for the time needed for the heating. Cooling either by inertia or with air-circulation around the tube.
Large capacity palaeointensity furnace
Pyrox furnace.
Up to 72 standard size samples.
Measurement in the morning, heating in the afternoon, cooling overnight.
Small capacity palaeointensity furnace
Homemade furnace.
8-9 standard size samples.
