When You’re Ready for an Upgrade

Priorclave’s 100L front-loading autoclave is an excellent upgrade for those who’ve outgrown their benchtop autoclaves. Moving to the cylindrical-vessel 100L doubles your capacity, increasing safety and reliability without sacrificing heating and cooling speed. This has made the 100L popular with community colleges, start-ups, and smaller research facilities.

Many of these facilities start out with mid-sized rectangular-vessel medical-grade sterilizers. These are great for quickly processing flat trays of medical instruments, but not great at anything else. This becomes more pronounced as the autoclave gets bigger: As rectangular chambers grow, operating costs and maintenance headaches can climb exponentially. Cylindrical-vessel front-loading sterilizers eliminate chamber corners, making for a more reliable device. Improved steam circulation prevents cold pockets, minimizing heating and cooling while ensuring properly processed loads.

The cost-savings associated with moving to a cylindrical vessel sterilizer are also impressive. A lower part count, more efficient steam generation, and lighter-gauge pressure vessel don’t just reduce the purchase price and nearly eliminate maintenance downtime: On an annual basis, a cylindrical-vessel front-loading autoclave can be expected to use 75% less energy and 87% less water than comparable “energy/water saving” rectangular models.

Every Priorclave autoclave is outfitted with an advanced Tactrol control system. These controls are optimized for research, with unparalleled cycle customization: One-touch operation, delayed cycle start, media warming, automatic cycle repeat, and more.

Priorclave front-loading autoclaves are built in the UK for years of trouble-free operation, even in the most adverse conditions. Their modular design is completely upgradable to meet your evolving needs. Each unit is designed for safe operation under all conditions, and fitted with the industry-favored Tactrol® 2 Control System. Priorclave autoclaves offer a 36-month limited parts and labor warranty, 20-year pressure vessel warranty, and unlimited technical support.


At Priorclave, the safety of your staff and students comes first. Our Quickseal 2 door with Permission-based Door Release is fitted with thermal and pressure locks to prevent opening at load temperatures above 80°C (176°F) and pressures above 0.2 Bar (2.9 psi) (as per BS 2646). The door is also fitted with a Redundant Safety Gate, so that any residual pressure can safely escape before the door can move freely (in accordance with the UK Health and Safety Executive’s note PM73). All units come with a Pressure Safety Valve set to 2.5 Bar (36.3 psi) and a 150°C (302°F) thermal cut out (per BS 6759); selected external panels and surfaces are thermally insulated. All front loading models have non-tip shelves.

Priorclave is the only manufacturer offering the same fully featured programmable control system on every model, from the smallest laboratory benchtop sterilizer to the largest industrial pass-through unit. The Tactrol 2 system puts every operating parameter within your control, with no re-training required as you move from one unit to another. Using our Tactrol 2 Control System, operators can limit user access to specific pre-programmed validated cycles via fail-safe one-button start. Program modifications are likewise key-switch or password protected.

All Priorclave autoclaves comply with current US, Canadian, UK, and EU safety regulations. They are manufactured under an ISO 9001:2008 quality management system in our UKAS-accredited facility. Our autoclaves and control systems are ETL listed and EMC certified, and feature ASME-stamped pressure vessels. These pressure vessels are manufactured entirely in-house, and tested to 1.5 times their maximum working pressure. They have full insurance approval for pressure vessel design and construction and are CE Marked under the Pressure Equipment Directive PD5500:2000 Cat 3, Certificate Number SS42059010-2 Rev 1. They also conform to the general requirements of BS 2646 and are CE Marked for BS EN61010-2-41, Low Voltage and Electromagnetic Compatibility.
