Description
A Kjeldahl digestion flask is designed for accurate nitrogen and protein determination using the Kjeldahl method, where consistent heating and chemical resistance are essential for reliable analytical results. Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, the flask provides excellent thermal stability, low thermal expansion, and strong resistance to concentrated acids and digestion reagents in accordance with ISO 3585 and ASTM E438 Type I laboratory glassware standards.
The distinctive Kjeldahl flask profile supports efficient heat distribution and controlled boiling during digestion, helping reduce bumping and sample loss. Its robust construction allows safe use on digestion units, heating mantles, or hot plates during extended digestion cycles. The smooth internal surface minimises residue retention and supports easy cleaning between analyses, maintaining consistency across repeated testing.
Supplied by LabChoice Australia, this Kjeldahl digestion flask is widely used in university laboratories, teaching facilities, food and beverage testing, environmental analysis, agricultural research, and industrial quality control laboratories across Australia. Its durability, accuracy, and analytical reliability make it an essential vessel for routine nitrogen determination, ammonia analysis, and Kjeldahl based laboratory workflows where precision and repeatability are critical.
