Language:

The Peak range 300 °C laboratory ovens are available in both PN natural convection and in the PF fan convection models. All PN models are bench mounted. In the PN ovens air circulation depends upon natural convection.

The resulting slow airflow is preferable, for example, for processes involving powders which may be disturbed by fan convection or where there is a risk of cross contamination between samples. 

The reduced complexity makes natural convection a less expensive option. It also allows for heat treatment in an ISO 8 working area.

Standard features

  • 300 °C maximum operating temperature
  • R38 PID controller (see below for other controller options)

- Shelf loadings are based on evenly distributed weight
- Maximum power and heat up times based on a 240V supply
- The uniform volume is smaller than the total chamber volume
