Liebig evaporator

Liebig Volatile Substance Evaporator

The Liebig volatile substance evaporator is a specialized device designed for releasing various volatile substances into the hive. The product excels in simple and safe dosing and is designed especially for effective and gentle use without significant interference with the normal functioning of the bee colony.

Description and Features

• Universal use: Can be used with commercially available volatile substances according to your preference.

• Permissions and legislation: In the Czech Republic, this evaporator is NOT approved for use with formic acid to treat bees. As a formic acid evaporator, its use is accepted in Germany. Follow the applicable regulations of your country!

• Evaporation principle: The system uses an absorbent paper wick placed on a base plate, into which acid from the container slowly drips and safely evaporates into the hive space.

• Easy application: Installation and operation are very simple and quick, suitable for both beginning and professional beekeepers.

• Tested and verified: The system has been long-term tested at beekeeping workplaces, for example in Hohenheim.

• Optimal dosing: The amount of evaporated substance is easily regulated by changing the size of the wick according to external conditions (temperature, solar radiation, type and size of hive).

Package Contents

• Bottle with child safety cap

• Control scale for dosing

• Dropper

• Base plate

• Four perforated paper wicks Liebig type

• Instructions for use

How the Liebig Evaporator Works

After filling the bottle with the chosen volatile substance (for German customers, for example, formic acid in the recommended concentration of 60-85%), the bottle is attached to the base plate. Using the dropper, the substance controllably flows onto the cellulose wick, which gradually releases the active substances into the hive. The wick is perforated, which allows easy adaptation of the size according to current conditions, and thus regulation of the amount of evaporated substance.

Advantageous Features of the Liebig Evaporator

• Minimal intervention in the bee colony

• Uniform release of the substance without risk of exceeding concentration

• Practical use especially after the honey harvest period (in Germany recommended in July/August and September)

• Easy status monitoring using the transparent bottle and scale

• Stable, effective and safe use

• Possibility of use in an empty super above the colony

Basic Instructions for Use

1. Prepare the evaporator according to the enclosed instructions (always use protective equipment - gloves, glasses!).

2. Insert the perforated wick on the base plate.

3. Fill the bottle with the required amount of evaporated substance according to your practices and current requirements.

4. Attach the bottle vertically to the base plate. Check for proper seating and tightness.

5. Place the entire system in an emptied super above the brood frames in the hive.

6. During evaporation, maintain ventilation - keep the entrance open, close the screened bottom boards.

7. After emptying the bottle, remove the evaporator and safely store it out of reach of children.

Safety Warnings

• Formic acid is highly corrosive - protect your skin and eyes and use protective gloves, glasses, and long-sleeved clothing when working.

• Keep clean water handy in case immediate washing is needed.

• Respect current regulations regarding the use of chemical substances in your country - in the Czech Republic, use with formic acid for treating bees is not permitted.

• For German beekeepers: never use cold formic acid - there is a risk of uncontrolled leakage and endangering the bees.

Optimal Timing and Recommendations for Use

• After honey removal - first application (in Germany July/August, period 3-5 days)

• After winter feeding - second application (in Germany September, period 6-14 days as needed)

• The size of the perforated area can be adjusted according to outdoor temperatures, type and size of hive

• After therapy, it is recommended to apply other products, e.g. Thymovar, for long-term protection

Why Choose the Liebig Evaporator?

• It sets a safe standard for regulated evaporation of volatile substances in beekeeping.

• Significantly saves time and facilitates handling compared to traditional methods.

• Provides optimal results in preventive and control measures in bee care.

• Does not disrupt the natural functioning of the bee colony, minimizes stress and the risk of residual substances in the wax.
