Phase behaviour of premixed 0 Phase behaviour of premixed 0.25% isoflurane in 50% nitrous oxide and 50% oxygen† M.E. Tunstall, J.A.

Fig 1 Variable scale broken diagram of test cylinder showing dip-tubes. A and B, gas sample pathway from bottom of cylinder. C and D, gas sampling and filling pathway from the top of the cylinder. E and F, insertion pathway for thermistor probe into closed end dip-tube. G, shrouded thermistor probe on surface of cylinder.

Fig 2 Trace of part of a recording of a cooling experiment. The upper trace is internal cylinder temperature and is offset to the left by the chart recorder pen position. First dew formation is indicated by the decrease in isoflurane concentration at A. Heavy vapour formation is indicated by the increase in concentration at B, which is then stopped by closing the valve at END. The internal cylinder temperatures at which A and B occur are at X and Y, respectively; offset in position by the chart recorder. The weight of gas in the cylinder at point A was 1361 g.
