60L - 150L Autoclave
Top-Loading & Vertical

Our #1 top-sellers worldwide! Why? Because vertical autoclaves can accommodate the tallest flasks, fermentors, and bioreactors at one-third the price of a comparable front-loading autoclave. Priorclave’s top loading autoclaves are among the most compact full-size units on the market today.  Compared to similar-sized medical-grade rectangular-vessel units, cylindrical autoclaves are easier to operate, less expensive to maintain, and more reliable over a longer working life.

Product Description

Top-loading autoclaves are very popular internationally and in for life-science research. Not only do they easily accommodate the tallest flasks, fermentors, and bioreactors, they’re also excellent for waste processing, especially in large batches (pop the lid and drop in the bag, just like a rubbish bin).

By relying on ultra-efficient cylindrical pressure vessels, Priorclave has engineered top-loading autoclaves that feature large capacities, low loading heights, small footprints, and low lifetime operating costs. Every Priorclave is custom built in our London factory, specifically to handle your applications.  All top-loading sterilizers can be outfitted for “gravity” or vacuum cycles, with in-chamber or independent heating. They come supplied with a stainless steel load support plate and stainless steel mesh baskets for optimal steam circulation. All models include the most current version of our full-featured, fully-programmable Tactrol Control System.

Does your facility or process pose formidable power, programming, or steam generation challenges? We specialize in custom-engineered solutions and are eager to discuss how best to meet your needs and exceed your expectations.

Installation Kit

UK brass fittings and copper tubing to assist in installation of Priorclaves.

Close

Internal Steam Generator

Integral Steam Generator for fitting to steam heated Priorclaves. Capacity and electrical requirements differ by model. For top Loading Priorclaves this option increases the width by 300mm.

Close

Auto-waterfill

Automatically re-fills the autoclave chamber while the door is open ready for the next cycle. Requires a water supply. (Fitted as standard to electrically heated vacuum models)

Close

IQ/OQ Documentation

Preparation of detailed IQ/OQ Documentation for testing purposes

Close

Pressure Recalibration

Where the autoclave is to be installed at higher altitudes an adjustment can be made to the autoclave alarms and settings to adjust for the differences in measured air pressures. Two bands are available: elevations between 900 and 2,400 M (3,000 to 8,000 ft.) – (0.9 to 0.75 Bar pressure) and elevations between 2,400 and 7,000 M (8,000 to 23,000 ft.) – (0.75 to 0.40 Bar pressure).

Close

Customer requested Pressure Vessel Approval

Form X Pressure Test Certification – Individually witnessed Hydrostatic Test with stamped certificate. MUST be requested at time of purchase.

Close

Adaptation for special water supplies

Electrically Heated Priorclaves require soft water with a conductivity of a minimum of 100 micro Siemens to work correctly. Various adaptations can be made to pipe work, fittings and water detection systems for Ultra pure water supplies if required.

Close

Additional Wire Baskets – Top Loading Priorclaves

Stainless Steel wire mesh baskets. In addition to those supplied with the autoclave in varying depths.

Close

Air Ballasting

Controls distortion of semi-rigid containers, pouches and blister-packs as the autoclave cools by pressurising the autoclave chamber with air, balancing the internal pressure inside the containers, pouches or blister packs. In autoclaves with water cooling jackets it controls volume losses when rapidly cooling liquid loads. Requires an extremal air supply at a minimum pressure of 3 BarG.

Close

Air Ballasting with built-in air compressor

Controls distortion of semi-rigid containers, pouches and blister-packs as the autoclave cools by pressurising the autoclave chamber with air, balancing the internal pressure inside the containers, pouches or blister packs. Includes a quiet running air compressor mounted, where possible, inside the autoclave body..

Close

Air Intake Filter

Protects sensitive loads from contamination from the outside air drawn in as the autoclave cools.

Close

Emergency Stop Button

Allows the operator to quickly shut down all autoclave functions in case of an emergency. Fitted as standard to all Power Door Priorclaves

Close

Exhaust Filtration

On cylindrical profile Priorclaves all autoclave exhaust is directed through a 0.2 micron HEPA filter housed externally. The filter is easily accessed for regular changing and all non-filtered condensate is returned to the autoclave chamber.

Close

Factory Acceptance Test

Factory Acceptance test carried out with the customer at Priorclave’s factory after manufacture and before despatch.

Close

Graphic Recorder Ethernet Port

Allows easy connection and integration to an internal computer network for remote monitoring and storage of records.

Close

Heater Protection

Backup thermostatic protection for the autoclave’s low water detection system.

Close

LoadLite Hoist – Top Loading Priorclaves 100L and above

Assists with loading and unloading heavy items and baskets for larger Top loading Priorclaves. Maximum individual load weight 50kG.

Close

Manual Drain

A manually operated valve is fitted to allow the autoclave vessel to be drain for regular cleaning.

Close

Operator Identification

PIN number identification of operators for each cycle. This information is recorded in the autoclave cycle log.

Close

Packing Case for Sea or Air Freight

Wooden Packing case for air or sea shipping. Fitted with shock and tilt indicators and the wood used is treated to ISPM15.

Close

Pneumatic Valves

Improves reliability and operation of complex Priorclaves. The standard electrical valves are replaced with pneumatically operated valves. Requires an air supply or alternatively a small quiet air compressor can be installed inside the body of the autoclave.

Close

Recorder – Circular Chart

Provides a temperature record of autoclave cycles independent of the autoclave control system onto a paper chart. Unless otherwise specified a fixed temperature probe is fitted. Multi-channel versions are also available.

Close

Recorder – Graphic – Logger

Provides a temperature and pressure record of autoclave cycles independent of the autoclave control system. Cycle records are graphically displayed and saved to a log file. Unless otherwise specified a fixed temperature probe is fitted along with a pressure transducer. Further recording channels can be provided along with the option of an Ethernet port for connection to a computer network.

Close

Recorder – Strip Chart

Provides a temperature record of autoclave cycles independent of the autoclave control system onto a paper chart. Unless otherwise specified a fixed temperature probe is fitted. Multi-channel versions are also available.

Close

Serial Communications Package

The autoclave is fitted with an external serial communication interface socket for connection to a suitable PC or laptop. The package includes a serial cable and software.

Close

Setting Lock

Tamper proofing of program settings for single program Priorclaves – Included on models fitted with multi-program memory options.

Close

Single Phase Connection

For 100 to 200L Priorclaves where a three phase supply is not available the autoclave can be wired to run at two thirds heating power from a single phase power supply rated at 32A. Should a three phase supply become available at a later time the autoclave can quite easily be re-wired for re-connection.

Close

Steam / Electric Heating

For Steam Heated autoclaves this allows the autoclave to continue to be used when external steam is not available.

Close

Steam Supply Set

Control and other valves required to supply a Steam Heated Priorclave with dry saturated steam at the correct pressure from an external steam supply. The autoclave is not fitted with this but if there is an existing steam supply set in place this can be used to supply the autoclave’s steam.

Close

TACTROL Self – Monitoring System

Provides an additional level of control protection. The Tactrol system scans all input channels to detect abnormalities and will abort the cycle with a displayed, logged and printed fault code and description if one is detected.

Close

Warranty Parts Only – 2 Years

Free of charge replacement of parts for two years. (Consumable items and damage due to misuse or negligence are excluded)

Close

Water Softener

Ion Exchange water softening system which provides water of the correct quality to run the Priorclave – requires regular refilling with salt to maintain water quality.
