Producing liquid oxygen in the classroom

Williams, David; Warden, Nicole; Wharton, Barry

Abstract

A number of organisations have provided instructions on how to produce small quantities of liquid oxygen in the classroom using liquid nitrogen and a copper condensation coil (Lister 1995 Classic Chemistry Demonstrations (London: Royal Society of Chemistry) pp 61–2, French and Hibbert 2010 Phys. Educ. 45 221–2). The method presented below describes a process which is believed to be safer as it contains the oxygen during production and produces a controllable amount of the liquid. The method also has the advantage that it can be conducted using cheap and easily available materials.
