Frequently asked questions
What is the difference between a natural-convection oven and a forced-convection oven?
The main difference is the air circulation system. In natural convection, air moves by density difference, providing gentle drying ideal for volatile samples or fine powders that must not be dispersed. In forced convection, a fan drives the air to achieve superior thermal homogeneity and much faster temperature recovery after opening the door, making it the ideal option for dense loads or large volumes.
What is a vacuum oven used for in the laboratory?
The vacuum oven is used to process samples that are heat-sensitive or that could oxidise in the presence of air. By reducing pressure, the boiling point of liquids drops, allowing the removal of solvents or moisture at much lower temperatures, thus preserving sample integrity.
When do I need a vacuum oven?
It is essential when working with heat-sensitive materials that degrade at standard drying temperatures. It is also required to remove solvents with high boiling points at low temperatures, prevent oxidation of metallic or chemical components, and dry very fine powders without them being projected by the air stream of a fan.
What is a Poupinel oven?
A Poupinel oven is a dry-heat sterilisation device. Unlike the autoclave (which uses steam), the Poupinel uses hot air at temperatures of 160 °C to 180 °C during 2-hour cycles to eliminate microorganisms. It is specifically applied to dry material that does not withstand water vapour, in food analyses such as oils, powders, petroleum jellies, or glassware that must be kept completely dry.
What temperature range do JP Selecta ovens cover?
Our range covers an exceptionally broad thermal spectrum to meet any technical need. We offer everything from precision incubators operating at 5 °C above ambient temperature to industrial muffle furnaces that reach 1,100 °C for calcination processes and advanced thermal analyses.
What is a muffle furnace and what is it used for?
A muffle furnace is an oven designed to reach extremely high temperatures (up to 1,100 °C or more) inside a chamber insulated with refractory materials. It is mainly used in laboratories for ash analysis, calcination of organic and inorganic samples, incineration and material resistance testing.
Do JP Selecta ovens comply with GMP standards?
Yes, our advanced models with TFT display and integrated datalogger are designed to comply with [GMP](https://www.fda.gov/drugs/pharmaceutical-quality-resources/current-good-manufacturing-practice-cgmp-regulations) and [FDA](https://www.fda.gov/) standards. We provide complete documentation for IQ/OQ/PQ validation protocols, total traceability of temperature cycles via USB/Ethernet export and alarm systems for any process deviation, facilitating quality audits.
What maintenance does a laboratory oven need?
To ensure precision and safety, regular cleaning of the interior chamber (stainless steel) is required, as well as checking the condition of the door gaskets to avoid thermal leaks and inspecting the temperature sensor. Annual calibration with traceable standards is recommended. You can request technical assistance in our technical support section.
