During a cyanoacrylate fuming cycle, cyanoacrylate will stick to the interior chamber surfaces as well as your evidence. A clean chamber surface will attract less cyanoacrylate buildup, making fuming your evidence more effective, and will reduce the risk of evidence cross-contamination. We have made it easy to clean our units between uses to reduce cyanoacrylate and DNA contaminants.

We use tempered safety glass in our fuming chambers. It is easy to clean and resistant to scratching. This can be wiped down with a microfiber cloth dampened with cleaning solution shortly after an evidence fuming cycle. If the chamber won’t be cleaned right after use, we recommend removing cured cyanoacrylate from the glass using a steel wool (grade 000) or plastic scraping tool.

While very abrasive and corrosive cleaning agents should not be used to clean the stainless steel floor of the chamber, it can be wiped down with a microfiber cloth and mild cleaning solution, and other solutions used for decontamination, including alcohol and peroxide-based cleaners.
During cleaning, we recommend removing the chamber circulation fan, water reservoir, and air baffle. These are easy to wipe down separately. Any electrical contacts should be covered during cleaning, and any residue should be wiped off to help keep them fully functional. When cleaning any chamber, we recommend vacuuming out the chamber after the rest of the cleaning has been done to remove any dust or fibers from steel wool or cleaning cloths.

The exact number of cycles your filter can be used for before it is saturated will depend on the type of developer you use and how much you use. Using more glue and developers that are more taxing on the filter life will of course mean your filter life is shorter than if you just use small amounts of standard developer. More details about this can be found in the filter management information section.

Using a typical amount of standard developer, our smaller MEGAfume S61 model can run around 180 cycles, the larger MEGAfume M61 around 120 cycles before the filter needs to be changed.

Users can keep track of the filter life on the filter management display, which will tell the user how much filter life they have left and when the filter needs to be changed. This can be done easily and without any special tools.

MEGAfume can be used with all known cyanoacrylate developers on the market, including one-step fluorescent developers. It can be used with developers that require temperatures between 100 – 250°C and 60-90% rH. Both liquid and powder developers can be used. Thanks to our cycle customization options that let you fully customize your cycle parameters, you’ll be prepared for developers that aren’t even on the market yet, making our systems more future-proof. Our filter management system can be adjusted for different developer types to accurately monitor your filter life, regardless of the type of developer you choose to use.

Our pre-programmed options include standard cyanoacrylate developer, and both liquid and powder fluorescent developer programs. In addition to the fully customizable program options, these pre-program cycle settings can be adjusted and saved as needed.

This depends on how long your evidence is. There is a great deal of variation in the lengths of things like bats, swords, and firearms. Currently, we have two basic sizes of MEGAfume models, the S61 and M61. The S61 has a chamber height of 75cm. If placed diagonally from the front to the back of the chamber, evidence as long as 90cm can be accommodated. This can be 109cm long if evidence is placed diagonally from a front to the back corner of the chamber.

The M61 model chamber height is 125cm. Diagonally, from front to back, evidence that is 136cm long can be accommodated. This is extended to 147 when evidence is placed diagonally from a front to the back corner of the chamber.
For larger pieces of evidence, we will be releasing the MEGAfume XL61 in Spring 2021. We also recommend looking at our MOBIfume mobile cyanoacrylate fuming system, which can be used to develop evidence in small fuming rooms or tents, and can be scaled to fume even larger spaces, like garages and hangars.

For those who often handle firearm evidence and longer pieces of evidence, we also recommend one of our MEGAfume evidence support system accessories, designed to hold and support longer pieces of evidence, including long-arms.
