Nassenheider evaporator - BienoPlastⓇ

Volatile Substance Evaporator Bieno Plast (Nassenheider Type)

The evaporator from the German manufacturer Bieno Plast is a proven tool for hive hygiene and controlled application of volatile substances in a bee colony. It is designed with an emphasis on safe operation, stable performance, and easy handling, making it suitable for both beginner beekeepers and experienced apiarists who want reliable and long-lasting equipment for their apiary.

Design That Maintains Even Evaporation

The key advantage is a well-thought-out design with a constant-level reservoir. Thanks to this, the liquid is continuously delivered to the wick in a constant amount until the reservoir is emptied. Evaporation is therefore consistent and does not depend on how much liquid remains. In practice, this means more stable release of the active substance into the hive space and a more predictable application process.

Durable Material and Simple Mounting in the Frame

The evaporator is made of food-grade polypropylene, which excels in chemical resistance and long service life. Installation is quick: the device is attached with screws or nails to the bottom bar of an empty frame. The prepared frame is then inserted and removed just like any other, which simplifies inspection and refilling while minimizing disturbance to the bee colony.

Adjustable Settings According to Colony Conditions

A practical benefit is the evaporation rate regulation by selecting the wick size (smaller/larger) according to the temperature and colony strength, including work with nucleus colonies. The sealed 200 ml reservoir is equipped with a clear graduated scale (calibrated up to 180 ml), giving you quick visual control of consumption and reducing the risk of spillage directly in the hive during refilling.
