Polydipsia is a syndrome characterised by an abnormal increase in water intake driven by increased thirst, leading to excessive urine production, known as polyuria, and resulting in more frequent and abundant urination.

Microplastics are small fragments of plastic that originate from the environmental or industrial breakdown of plastic polymers such as polyethylene, polystyrene or polypropylene.

Formol Number, also known as Formol Index, measures the content of Primary Amino Nitrogen (PAN) from free amino acids and ammonium present in a sample. It is used as a quality parameter of fruit juice, grape must and wine.

When it comes to winemaking or brewing, fermentation is more than a simple metabolic process. Success on this key step greatly depends on the yeast assimilable nitrogen (YAN).

Absorption photometry is an analytical technique that measures the amount of light absorbed by a liquid solution, at a specific wavelength, in order to determine the concentration of an absorbing substance. In this technique, a beam of light passes through a solution, and the decrease in light intensity due to absorption is measured.

Although some yeasts can produce sulfites in small quantities, winemakers also add them deliberately to help the wine maintain its quality over time.

At BioSystems, we're always evolving to meet your needs and expand our analytical solutions portfolio. This year we have introduced our new Complete Immunofluorescence Assay (IFA) System, designed for seamless, high‑accuracy autoimmunity testing.

LEDs (Light Emitting Diodes) are now a widespread and well-known light source in our ordinary life, very reliable, and with very low energy consumption. But more than 15 years ago, BioSystems pioneered its use in the clinical and food analysis laboratories.
