Gas-powered oxalic acid sublimator developed by experienced beekeepers
The gas-powered oxalic acid sublimator is the work of experienced beekeepers who invested a great deal of effort, knowledge and practical experience into the final product.
Because they know the needs of beekeepers from hands-on practice, they created a device that best helps in real-world beekeeping work.
Make your work easier and much faster
Maintaining a colony can be demanding and time-consuming, and Varroa control is a task most beekeepers would rather get over with quickly.
The gas-powered oxalic acid sublimator allows you to perform this task in an incredibly fast and extremely simple way.
Gas-powered oxalic acid sublimator — temperature control
Our gas-powered oxalic acid sublimator does not have an integrated temperature controller, but with the correct procedure the temperature can be controlled easily and precisely. Simply follow the steps below to achieve optimal sublimation results:
- Flame setting: Use a low flame that provides safe and even heating.
- Heating: Heat the sublimator until white vapor appears. This indicates the ideal temperature for sublimation has been reached.
- Extinguish the flame: Put out the flame as soon as vapor appears. This prevents overheating of the oxalic acid and protects the device from damage.
- Application at the hive: Insert the sublimator into the hive entrance and wait until the vapor emission stops. The device remains hot enough to complete sublimation without further intervention.
- Repeat: For the next colony, fit a new cap with the required dose of oxalic acid. Relight the flame and heat the sublimator until vapor appears again, then extinguish the flame.
Our sublimator was tested by the Faculty of Mechanical Engineering in Maribor, Slovenia. The comparison between our gas model and an electric device with temperature control showed both systems deliver similar results with no significant differences.

Learn all the benefits of the gas-powered oxalic acid sublimator
Our gas-powered sublimator is thoughtfully designed and manufactured, offering beekeepers many practical advantages.
A product tailored to beekeepers' needs
The gas sublimator was developed by experienced beekeepers who relied heavily on their practical experience during production. It is optimally adapted to beekeepers' needs, easing their work and saving significant time.
Three dosing caps for continuous work
The three included dosing caps allow you to continue sublimation without waiting or risking burns. One cap can be used for sublimation while a second is being filled with oxalic acid and the third cools and is ready for the next use.
Scoop for simple and precise dosing
Accurate dosing is essential when sublimating oxalic acid. The supplied scoop lets you measure the correct amount simply and safely. It can also be used to clean the discharge tube.
Flexible hose for easier access to the hive entrance
The flexible hose supplied with the gas sublimator provides easy access to the hive entrance, allowing you to sublimate more easily, quickly and precisely.
Careful, precise manufacturing for excellent quality and reliable performance
The gas sublimator is produced from quality materials using modern technology, delivering exceptional durability and trouble-free operation.
Advanced and precise design and manufacture
The gas sublimator was designed using advanced 3D CAD tools and manufactured on highly accurate CNC machinery.
Carefully selected materials
The sublimator body is made of durable, lightweight aluminium, and the anodized surface improves resistance to acids and high temperatures.
Color change of the sublimator
The gas sublimator is made of anodized aluminium in black. Anodizing converts the outer aluminium layer into an oxide layer that provides excellent protection against corrosion, wear and acids. The surface will not melt when heated and does not release odors as conventional paints might at high temperatures. During use the color of the sublimator may change from black to brown–gold. This is expected and does not indicate any device fault.

Great performance with a Kemper gas burner
The gas-powered oxalic acid sublimator is suitable for use with burners that have a nozzle diameter of 21.2 mm.
It was tested with the Kemper 1060 gas burner, which offers:
- Piezo ignition system for safe and convenient lighting
- Ergonomically shaped handle for comfortable operation during sublimation
- A nozzle to regulate air intake and thus flame intensity
We recommend using the gas sublimator together with the Kemper 1060 gas burner.
The sublimator is also compatible with other gas burners, provided they have the correct nozzle diameter (21.2 mm).
Replacement cartridges are easy to obtain
The gas burner uses threaded gas cartridges, which provide a simple and secure attachment of the burner head to the cartridge.
The cartridges contain a butane/propane mix so the burner will operate at lower outdoor temperatures. Replacement cartridges are widely available from hardware stores (e.g. Bauhaus, Obi) and can also be ordered from our website for direct delivery.

Dosing oxalic acid
The recommended amount is 1–2 g of oxalic acid per bee colony, depending on the recommendation of your veterinarian or an experienced beekeeper.

Pour the measured powder into the supplied caps and you are ready to start sublimation.
For simpler dosing you can also use oxalic acid tablets.
Instructions for use
The gas-powered oxalic acid sublimator is practical and very easy to operate. For an easier start we have prepared a short guide.
- First, screw the gas burner onto the gas cartridge, then place the sublimator on the burner and secure it with the supplied clamp.
- Preparation of the oxalic acid: Use the supplied scoop to measure approximately 1–2 g of oxalic acid into each cap.
- Now turn the device to the side and fit a cap with oxalic acid into position. The oxalic acid is still in the cold cap and has not yet sublimated.
- Turn the device back to its operating position so the oxalic acid powder falls into the sublimation chamber. If the sublimator is already heated, sublimation will begin immediately and white vapor will be emitted.
- Insert the gas sublimator into the hive entrance so the vapour of sublimated oxalic acid can penetrate the hive. The sublimation process takes about 30–45 seconds.
Safety warning
It is important that you only light the gas burner flame briefly — just long enough for the central chamber of the sublimator to heat up and sublimation to begin. This is when white vapor starts to appear from the device. Then extinguish the flame. This reduces gas consumption and prevents overheating of the oxalic acid or damage to the sublimator.
Use the lowest flame power that still provides sufficient combustion. To keep the flame temperature as low as possible, the burner air intake openings should be as closed as feasible.
The gas sublimator is made of aluminium, whose melting point is lower than the maximum flame temperature the burner can produce. Prolonged heating of the sublimator for several minutes at maximum flame can cause irreparable damage. Therefore, extinguish the flame as soon as it is no longer needed.
Caution! Hot!
The gas sublimator becomes very hot during operation. Do not touch it without appropriate heat-resistant gloves!
Protective equipment
Always use suitable respiratory protection during sublimation!
