Description
A jointed Kjeldahl digestion flask is designed for precise nitrogen and protein determination using the Kjeldahl method, where secure connections and controlled digestion conditions are essential. Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, the flask delivers excellent thermal stability, low thermal expansion, and strong resistance to concentrated acids and digestion reagents, meeting ISO 3585 and ASTM E438 Type I laboratory glassware standards.
The classic Kjeldahl flask shape supports efficient heat transfer and stable boiling during digestion, helping to reduce bumping and improve reaction consistency. The precision ground joint allows direct, leak free connection to distillation apparatus, condensers, and adapters, enabling smooth transition from digestion to ammonia distillation without sample loss. Uniform wall thickness enhances durability during prolonged heating on digestion units or heating mantles, while the smooth internal surface minimises residue retention and simplifies cleaning between analytical runs.
Supplied by LabChoice Australia, this jointed Kjeldahl digestion flask is widely used in university laboratories, teaching facilities, food and beverage testing, agricultural research, environmental analysis, and industrial quality control laboratories across Australia. Its robust construction and analytical reliability make it an essential vessel for accurate Kjeldahl analysis, ammonia recovery, and routine nitrogen determination where precision, safety, and repeatable results are critical.
