Laboratory Products 43 High-Performance Autoclave for Food Producers
The Priorclave EH320 cylindrical chamber laboratory autoclave fitted with a vacuum drying option is attracting the attention of mycologists and food producers, and in particular mushroom growers. This is because it has the ability consistently and reliably sterilise challenging loads such as grain.
Grains like wheat and rye berries are an almost ideal medium for germinated mushroom spores. Not simply because they are nutrient-rich, each individual kernel of grain acts as its own inoculation site for mycelium. Allowing mycelium to flourish in the controlled environment of grain spawn lays the necessary groundwork for them to reliably outcompete any other microorganisms in their bulk substrate.
Complete sterilisation of mushroom grain bags and any grain to be added to bulk substrate is essential. But creating a sterile grain bag for mushroom cultivation is a challenge. Contamination is the most common source of failure and tends to come from improper preparation of bulk substrate prior to inoculating it with mushroom culture.
Bacteria are both the most numerous biological contaminants and the most troublesome. Moist, room-temperature bacteria double every 20 minutes or so. In theory, a lone surviving bacterium in a heat-sealed grain bag will spawn more than a million offspring in just 10 hours. That one bacterium can recolonise an entire batch of substrate in a few days.
So, whether it’s for research or cultivation, properly preparing the fungus substrate is essential and that is where the EH320 autoclave from Priorclave with a vacuum facility is proving successful. The combination of features such as forced air cooling to reduce cycle times and automatic timed free steaming for improved air removal and vacuum facilities all add to the overall sterilising performance, particularly in labs involved with grain cultivation.
Priorclave designed the cylindrical chamber of the EH320 with a taller profile than that found in most ‘cylindrical’ machines, in fact it has a 630mm diameter chamber which is 1025mm deep. This makes it a viable alternative to large more costly rectangular autoclaves, able to achieve the same sterilisation throughput.
The front-loading EH320, cylindrical chamber autoclave from Priorclave is becoming a preferred choice is support of mushroom cultivation. More information online:

2-channel System for Catalytic Flow Chemistry
The FlowLab Column™ from Uniqsis is an affordable flow chemistry system designed specifically for high temperature and pressure catalysis applications. At the heart of the FlowLab Column™ is a HotCoil heated reactor module fitted with a HotColumn adapter to enable operation up to +260°C (300°C as an option). Developed as a high-performance alternative to conventional stirred batch reactors – the FlowLab Column™ can accommodate six stainless steel columns in individual insulated holders, each capable of operation up to 100 bar (200 bar option). This in-series configuration facilitates easy scale up and high catalytic yields.
FlowLab software provides control of the system via a step-through interface that can be learnt in minutes and is highly intuitive to use. Programs can be designed and saved reactions run automatically, including priming and washing. The program is monitored on a real-time display showing temperatures and pressures. FlowLab software also automatically detects any modules that have been added to the system.
