PASCO Wireless Ethanol (Vapor) sensor allows students to study another major metabolic pathway involving fermentation. Good for understanding fermentation of solutions to generate alcohol, study Raoults law of partial pressure over solutions and even concepts of distillation
- 1x Short segment of Teflon tape
- 1x Polyethylene bottle for calibration
- 1x USB C charging & communication cable
- 1x Large holed #6 Stopper for use in flasks and collection bottles
Product Summary
The Wireless Ethanol Sensor measures the concentration of gaseous ethanol up to 3%. In biology and environmental science labs, students can learn about anaerobic respiration by measuring the production of ethanol by bacterial or yeast fermentation. Physics students can begin to explore combustion and thermodynamics. Chemistry students can compare vapor composition over simple solutions. Connect your students to studies of fermentation, respiration, solutions, and generation of alternative energy sources with the wireless Ethanol Sensor.
Note: This is a gas sensor - it should not be submerged in liquids. If exposed to gases with ethanol concentrations above the recommended maximum of 3% the sensor element's life span may be shortened.

Fermentation (Available only in Digital Format)
Students use a Wireless Ethanol Sensor with Display (PS-4252) to determine the ability of yeast to use different types of carbohydrates for fermentation.
Fermentation
In this lab, students determine the ability of yeast to use different types of carbohydrates—sucrose and starch—for fermentation and monitor the reaction using an ethanol sensor to differentiate this process from respiration.
