Laboratory Ovens

JP Selecta laboratory ovens cover a broad spectrum of thermal applications: sample drying, dry-heat sterilization, microbiological culture, accelerated aging tests, adhesive and resin curing, and controlled heat treatments. For applications requiring controlled temperature in liquid media, see our thermostatic baths and immersion thermostats.

The operating principle combines shielded electric resistors with mineral wool or ceramic fibre insulation systems that minimize heat losses. The thermal uniformity and stability required by the DIN 12880 standard on electrical laboratory devices (ovens and incubators) is guaranteed by digital PID control with high-precision Pt100 sensors calibrated against NIST Thermometry program standards.

The range includes natural convection ovens for lightweight samples and gentle drying, forced convection ovens with internal fan that ensures thermal uniformity throughout the chamber, vacuum ovens for low-temperature drying of heat-sensitive samples, and muffle furnaces with ceramic chamber for thermal treatments up to 1,100 °C. Construction specifications follow the guidelines of the ASTM E145 standard on gravity-convection and forced-ventilation ovens.

Applications cover dry-heat sterilization (160-180 °C for 2-4 hours) verifiable with biological indicators per ISO 11138-4, moisture and dry matter determination in food analysis (see our food analysis equipment), microbiological culture in ovens with regulation between 20 °C and 70 °C, and pharmaceutical stability testing in accordance with ICH guidelines.

All JP Selecta equipment meets the electrical safety requirements of IEC 61010-1 and the particular requirements for laboratory equipment for the heating of materials in IEC 61010-2-010. For laboratories accredited under ISO/IEC 17025 we provide qualification documentation and traceable calibration, as well as support for analytical instrument qualification described in USP <1058>.

Manufactured in Abrera under ISO 9001:2015 and ISO 14001:2015 certifications, JP Selecta ovens include downloadable technical documentation, official technical service with our own network and guaranteed access to original spare parts throughout the equipment lifecycle.
