Name: Carbolite CR Clean Room Oven - Opti-Tech Scientific Inc
Availability: InStock

The CR Clean Room Oven Series of 250 °C ovens comprises nine standard models in sizes from the 30-litre model to the 1810-litre model, which, once processed through a customer’s standard material entry regime, are suitable for operation within an ISO 14644-1 Class 5 environment*.

All sources of particulate contamination are fully sealed. Their easily cleaned stainless steel interiors and gloss white epoxy exteriors prevent the shedding of particulate contamination.

*Federal Standard 209E Class 100 was superseded in 2001 by ISO 14644-1 Class 5

Please note
– Uniformity is measured in an empty chamber with vents closed after a stabilization period
– Shelf loadings are based on evenly distributed weight
– Minimum operating temperature approximately ambient +30°C
– Maximum power and heat-up time based on a 240V supply
– The uniform volume is smaller than the overall chamber volume
