New Lab Ovens Combine Economy with Temperature Uniformity and Stability
A lower maximum temperature and associated re-engineering have enabled Carbolite (Hope Valley, nr Sheffield, England) to offer three new laboratory ovens at considerably lower prices than existing equivalent models without reducing temperature uniformity and stability.
While Carbolite's existing Peak series ovens operate to 300°C, the new Apex ovens - which are available in 30l, 60l and 120l sizes - operate up to 250°C, sufficient for many sample heating and hot air sterilisation procedures.
The ovens have fan-assisted air circulation which provides a uniform temperature throughout the chamber, rapid heat-up rates and quick temperature recovery after reloading. At 100°C temperature variation within the chamber is only ±0.9°C, while at 250°C the maximum variation is ±3.4°C. Temperature stability is ±0.2°C for all models and heat-up time to 250°C for the AX60 is 25 minutes.
Carbolite adds that efficient insulation reduces power requirements and ensures comfortable outer-case temperatures. A PID controller and stainless steel interior lining are also standard equipment. A digital count-down timer and over-temperature protection can also be fitted.
