Take control of off-flavors in your beer and wine with "sulfur sticks," a hydrogen sulfide detection tube.

The tubes can easily detect all possible sources and factors that may cause overproduction of H₂S.

The tubes are easy to use. Insert the tube into a pre-bored silicon rubber stopper. The tube is pre-calibrated with a standard H₂S gas. Let the wort (or must) ferment .... then read the amount of H₂S produced directly from the scale imprinted on the tube.

Multiple fermentation experiments can be conducted in your bench space or incubator.

The tube responds to varied amounts of H₂S in a linear, uniform and proportionate manner.

The tubes are sold in packs of 10:

TK3498-10; Sulfide Detection Tubes, Fermentation Monitoring (99-005) - $100

TK3499-10: Sulfide Detection Tube, Finished Beer & Wine (99-001) - $75
