Laboratory gas-heated oven for drying or sterilising using hot air, with base stand, probably dated to the early 20th century. The maker is unknown. The oven contains two tubulures on top, in which a thermometer and thermostat can be fitted, and an air regulator in the door. The heating source would be for example a Bunsen burner placed below the oven (Figure 1).
