16 g CO₂ cartridge for the Varroa Tester. A spare for CO₂ counting as part of varroa monitoring: it helps obtain an adult-bee infestation reading, but it is not a treatment and does not replace later control decisions.
CO₂ is used in the Varroa Tester as part of the diagnostic process. The reading helps compare colonies, make better decisions and check varroa pressure instead of working only by eye or a fixed calendar.
The product has two versions: threaded, compatible with the older Varroa Tester model, and unthreaded, for the newer pistol model. Check your device before ordering, because cartridges can look similar but fit differently.
