autoclave

Though I did enjoy the fellow who suggested that he sterilized everything in his kitchen with a Harvest Gold autoclave.

Sterilisation by means of superheated steam is carried out in a special boiler—Chamberland's autoclave (Fig. 30).

Fix the bucket over a large Bunsen flame and boil for thirty minutes—or boil in the autoclave for a similar period.

Heat the whole apparatus in the autoclave at 120° C. for twenty minutes.

Steam applied in an autoclave under a pressure of two atmospheres destroys even the most resistant spores in a few minutes.

The author found that in an autoclave of the type shown in Fig. 81 it required ten minutes for 500 cc.
