Frequently asked questions

What is a laboratory autoclave and what is it used for?

A laboratory autoclave is a sterilisation device that uses high-pressure, high-temperature steam to eliminate microorganisms, spores and viruses. It is mainly used in the pharmaceutical, food, research and healthcare industries to sterilise instruments, culture media, containers and biological waste, ensuring a safe and contaminant-free working environment.

What is the difference between a benchtop autoclave and a vertical one?

The main difference lies in capacity and space. A benchtop autoclave is compact (8 L to 28 L), easy to install and does not require water connection, ideal for clinics and small laboratories. A vertical autoclave offers greater capacities (up to 150 L) and can process larger volumes or complex materials thanks to advanced technologies such as fractionated vacuum or fast cooling systems.

What certifications must laboratory autoclaves comply with?

To ensure process safety and validity, a laboratory autoclave must comply with the European standard [EN 285](https://standards.cencenelec.eu/dyn/www/f?p=205:32:0::::FSP_ORG_ID,FSP_LANG_ID:6028,25&cs=10C5BFCCB1CD0E5E96D5D9C2A4B3CFEFA) (for large steam autoclaves) and, in regulated environments, with [GMP](https://www.fda.gov/drugs/pharmaceutical-quality-resources/current-good-manufacturing-practice-cgmp-regulations) (Good Manufacturing Practices) and [FDA](https://www.fda.gov/) directives. The manufacturer must also provide IQ/OQ/PQ validation protocols to ensure the equipment operates according to technical and legal specifications.

How often does an autoclave need to be calibrated?

Certified calibration is recommended at least once a year, or more frequently in laboratories under strict regulations. Calibration ensures that the temperature and pressure sensors maintain the traceability required for critical processes. You can request this specialised service in our laboratory calibration section.

What maintenance does a JP Selecta autoclave need?

Preventive maintenance includes periodic cleaning of the chamber, inspection of the door gasket and replacement of biological filters. Regular maintenance avoids unplanned stops and extends the service life of the equipment. Our team offers technical support and maintenance plans to ensure optimal performance of your autoclaves.

Do JP Selecta autoclaves have a fast cooling system?

Yes, our advanced models (such as the Autester ST DRY GMP series) incorporate the Fast Cooling system. Thanks to a vacuum pump we force cool air from outside in and expel hot air from inside, creating a continuous airflow that quickly dissipates heat.

Do they include a counterpressure system?

We have specific models with compressed-air counterpressure technology such as Autester ST DRY GMP/USB and Steril Press. This system is essential for sterilisation of liquids in sealed containers (such as serum bags or vials), as it compensates the internal pressure of the container during heating and cooling, preventing deformation, breakage or explosions.

Do they have vacuum drying?

Yes. Our Autester ST DRY models feature a powerful vacuum drying system with a double-stage pump. This process removes air from the chamber before sterilisation (fractionated vacuum) and extracts residual moisture at the end, leaving porous materials, textiles and complex instruments completely dry.

What is the duration of an autoclave cycle?

Total duration depends on the load, the program and the selected temperature (typically 121 °C or 134 °C). A standard cycle can last between 20 and 60 minutes, plus heating, pressure equalisation and cooling times. Using systems such as vacuum drying or fast cooling can significantly reduce the total cycle time.

What is the maximum autoclave temperature?

Our autoclaves reach working temperatures of up to 134 °C - 135 °C (approximately 2.1 bar of pressure). This range allows compliance with the most demanding sterilisation protocols, ensuring elimination of pathogenic agents in the shortest possible time for applications on both solids and liquids.
