Maximum capacity, minimal footprint: Rethinking autoclave design for modern research labs

Laboratories often assume high-capacity autoclaves must be large, front-loading units that dominate floor space. For many research applications, this is unnecessary. The main requirement is vertical clearance for tall vessels, not expansive horizontal volume.

Priorclave, a UK-based manufacturer renowned for precision-engineered autoclaves, has addressed this need with its top-loading designs. These units offer substantial chamber capacity while maintaining a compact footprint - typically no wider or deeper than one metre. This enables tall loads to be processed efficiently while reducing energy, water use, acquisition costs, and improving throughput.

Among Priorclave’s top-loading offerings, the EV200-SMART stands out with a vertically oriented 200-litre pressure vessel. Engineered for demanding research environments, this autoclave integrates advanced sterilisation features, including: 

•  Automatic timed free-steaming
• Forced air cooling
• Multi-stage pre-cycle vacuum with interspersed heating
• Vacuum-assisted drying 
• Pulsed free-steaming to enhance vacuum efficiency

These features ensure thorough sterilisation of complex and porous loads, making the EV200-SMART ideal for microbiology, molecular biology, and bioprocessing workflows. 

The EV200-SMART’s pressure vessel is insurance-approved with a 10-year warranty. Thermal and pressure interlocks prevent access above 80°C or 0.2 bar.

All Priorclave autoclaves are equipped with the proprietary Tactrol® 3 controller, offering intuitive, glove-friendly operation and fully programmable cycles. The unit’s epoxy-coated panels and frame are treated with a long-lasting antimicrobial agent effective against all known bacteria and fungi, including MRSA - supporting aseptic conditions and simplifying cleaning protocols. 

Recognising that not all labs require a 200-litre chamber, Priorclave offers the EV-SMART series in 100-litre and 150-litre models as well. For facilities with less complex sterilisation needs, a Basic edition is also available - omitting vacuum features while retaining core performance and safety standards. 

Priorclave is one of the few autoclave manufacturers globally to maintain complete control over its supply chain. All principal components are fabricated in-house at their London facility, including pressure vessels produced using a proprietary seam welding system. This commitment to craftsmanship ensures long-term durability and consistent performance - hallmarks of the brand’s reputation.

Priorclave continues to set the standard for autoclave innovation - delivering high-capacity sterilisation without compromising space, safety, or sustainability.
