Description
Kjeldahl Distillation Assembly (Markham Still) – EISCO (Cat # 09 027)
The EISCO Kjeldahl distillation assembly — also known as a Markham still — is a complete apparatus designed for distillation steps in Kjeldahl nitrogen/protein analysis. This system integrates boiling flask connections, condenser columns, and receiving tubes to facilitate efficient steam distillation of ammonia from acid-digested samples.
Constructed from high-quality borosilicate glass, it offers excellent thermal stability, chemical compatibility with digests and reagents, and seamless integration with laboratory heating and vacuum systems. Ideal for dairy, food, environmental, and agricultural laboratories conducting routine Kjeldahl analysis.
