Arupu TR-24LA Autoclave with 22L Stainless Steel Chamber and Digital Controls

The Arupu TR-24LA is a benchtop laboratory autoclave designed for sterilization tasks critical in molecular diagnostics, bioprocessing, and biotechnology research. It features a 22-liter stainless steel (SUS304) pressure vessel with internal dimensions of φ240×448 mm. Heating is provided by a 1.4 kW electric pipe heater allowing sterilization temperatures between 105°C and 127°C under pressure (0.02 to 0.16 MPa), suitable for effective microbial inactivation.

Key operational features include a digital temperature display with 1°C resolution, an analog pressure gauge (0–0.4 MPa), and a programmable timer ranging from 1 minute to 99 hours 59 minutes. The unit employs a temperature-sensing and time-controlled electromagnetic valve system for air exhaust, enhancing sterilization reliability for sensitive biotechnological materials. Safety mechanisms encompass lid interlock, dry burn protection, an overpressure safety switch, a safety valve, and a safety breaker to ensure secure operation in laboratory settings.

Constructed with durable materials — including an outer steel casing with melamine coating and heat-resistant resin lid cover — it provides robust physical protection while maintaining ergonomic handling. Mobility is provided by 40 mm diameter caster wheels with front brakes, facilitating easy repositioning. The compact external dimensions (371×432×786 mm) make it ideal for space-constrained biotech labs engaged in sterile processing workflows such as gene editing experiments, biopharmaceutical production pipelines, and molecular cloning sterilization protocols.

This used autoclave is sold as-is; potential buyers should verify operational status. It remains a valuable instrument widely utilized for sterilization in biotechnology, biomedical engineering, and clinical diagnostics, meeting the rigorous demands of modern molecular biology research and biomanufacturing applications.
