Optimize your lab workflow with the Rhizo Funga Touch-Less Induction Sterilizer, the first ergonomic, sensor-activated sterilizer designed specifically for mycological tools. Unlike traditional models that require constant button-pressing or foot pedals, the Rhizo Funga uses a proximity sensor and programmable timer relay to deliver hands-free, consistent sterilization every time. Just place your tool in the heat resistant tool slot - no need to press, hold, or wait around 

This smart, tabletop unit heats your scalpel or other metal tools to sterilization temperatures within seconds. Once the preset cycle completes, the coil automatically shuts off, allowing the tool to cool in place—ready when you are. With fully customizable timing, you can adjust sterilization duration to fit your specific tools and protocols.

Built for efficiency and comfort, the Rhizo Funga sits at standard table riser and features an integrated blade holder for convenience. Designed for durability and ease of maintenance, most components are user-replaceable with a standard screwdriver. A red LED indicator clearly signals when the unit is active, and it comes complete with a 12V DC power supply.

Ideal for both professional and hobbyist mycologists, the Rhizo Funga Induction Sterilizer not only saves time—cutting down the brief, but repeated attention typically required for sterilization during culture work, but eliminates tool holding, button pushing and placing the tool for cooling . Once you use one, you won’t want to go back.

If you are comparing autoclave, UV, alcohol, flame, bead, infrared, or induction sterilizers for mycology, the difference is workflow. These are built for the between plates moment.

Compared to common alternatives

Autoclave and UV are effective, but they are not practical for continuous reuse of the same tool during a session. Autoclaves run in batches and take time. UV needs dwell time and line of sight and it does not solve tool parking between plates.

Alcohol wipes or dips help with general sanitation, but they are not a fast repeat cycle sterilization method. Alcohol needs adequate contact time and the tool must fully dry before use. Wet alcohol introduces extra handling and can disrupt sterile technique between plates.

Traditional induction often requires a button or foot pedal and you still need a place to set the tool down between uses. Torches have the same workflow issue and add extra motion and residue risk. Bead and infrared units often require warm up or preheat and add maintenance or always hot wear.

Why fully automated matters

Sterile work involves frequent sterilization and frequent moments where you need both hands. With a fully automated cycle, you place the tool in or on the unit and continue working. The tool stays parked safely between uses and is ready when you reach for it again.

Compared to the The LabRat

FlatTop delivers the same hands free automation as LabRat, using the same core components. It is open, which makes it simpler to wipe down and some labs prefer that. FlatTop is also a great value option at a lower price point.

The FlatTop has an open design so it accepts a wider variety of tools. It can also handle syringes with ferrous metal needles because there is no insert housing constraint.

The FlatTop is open for the fastest wipe down and simplest access.

Frequently Asked Questions

An induction sterilizer uses an electromagnetic field to heat the metal portion of your tool to sterilizing temperatures in a controlled way. You get consistent, repeatable sterilization without open flame, soot, or burning alcohol. This keeps your workflow cleaner and safer around alcohol wipes, 70 percent spray, and filtered air. It also frees up your hands so you can focus on sterile technique instead of fighting with a torch.
You insert the metal portion of your tool into the heating zone and the induction coil rapidly heats only that metal. The tip reaches red-hot sterilizing temperatures within a set cycle, then begins to cool while staying in the housing. You remove the tool once it has cooled to a usable temperature and go straight back to work. The electronics manage power and timing for you so you get the same result every cycle.
The unit works best with magnetic stainless steel tools such as scalpels, forceps, tweezers, and inoculation tools designed for mycology. Non-metal or low-metal tools will not heat properly because induction relies on the metal itself to generate heat. Avoid plastic handles or parts inside the heating zone unless they are rated for high temperatures. Always check your specific model’s compatibility notes before using a new tool.
Yes. You remove open flame from the equation, which lowers the risk when you work around isopropyl alcohol, paper towels, and plastic bags. The heating element is enclosed, and the tool only heats when it is in position and the cycle is running. That reduces accidental burns, flare-ups, and hot tools rolling around your workspace. It is still a high-temperature device, so you should follow the safety guidelines and let tools cool before use.
Set the unit on a stable, ventilated surface, plug it into the correct power source, and follow the startup steps in the manual. Run a test cycle with a tool so you understand how hot it gets and how long it takes to cool to a working temperature in your environment. Keep the tool housing free of debris and wipe the exterior down regularly to prevent dust and spore buildup. Do not spray liquid directly into the housing and avoid blocking any vents so the electronics can stay cool and reliable over long sessions.
Rhizo Funga micro sterilizers are designed for laboratory, hobby, mycology and plant tissue work. They are not intended for medical, surgical, or clinical applications. Use only for heating and sterilizing tools related to mushroom cultivation or related plant lab work.
