The Laboratory is equipped for pollen extraction from sediments and morphoscopic analysis of fine-grained microscopic organic matter: hoods, centrifuges, air pump, stirrer, sieving systems, glassware.
The CNR - IGAG Laboratory owns a LECO®TGA 601 thermogravimetric analyzer for automated analysis on water, total organic matter, carbonate, silicoclastic and oxides components of sediment samples.
Sediment samples for macro-remains analysis are processed in the Laboratory equipped at the CNR - ARM3 Area.
Lab1
The Laboratory of Palynology and Palaeoecology is equipped with four biological microscopes and one stereomicroscope provided with digital camera. In the CNR - ARM3 Area one additional biological microscope and one stereomicroscope provided with digital camera are available.
A microscope for bright and dark field observations, used for anthracological analysis, is available at the CNR - ARM3 Area. The reference collection of charcoal is in progress and consists of ca. 75 species.
The reference pollen collection includes 1551 pollen samples belonging to 648 species especially documenting the Alpine and Pre-Alpine flora. It is available in two copies at the Laboratory of Palynology (Università di Milano Bicocca) and at the CNR - ARM3 Area.
The reference collection of plant macroremains (seeds, fruits and vegetative parts) includes 909 samples belonging to 562 species. It is available at the CNR - ARM3 Area.
Manual corings in sediment and soft soils down to 10 m depth: the Laboratory is equipped with undisturbed peat corers of various lenghts and diameters, gouge and Edelmann augers, tools for percussion and extrusion. They may operate in inconvenient locations and extreme environments. CNR-IGAG also holds expertise in geophysical prospection supporting projects of deep coring (https://www.igag.cnr.it/lista-laboratori/geofisica-applicata/).

Deep continuous corings with scientific purposes (idraulic extrusion and specific feed) are usually carried out by specialized firms.

The position of corings and samplings can be accurately set thanks to the total station available in the Laboratory of Palynology.

Sediments are usually sampled with volumetric piston samplers, enabling the sampling of precise volumes of sediment to be further treated in the laboratory.

The core repository of the Laboratory of Palynology is housed at the CNR - ARM3 Area. Cores drilled during coring campaigns are stored there.

Cores obtained with manual coring and stored in plastic tubes are usually kept in fridges under constant temperature and humidity, to avoid desiccation and mould.
