Students can now safely produce a vacuum in a small bell jar right at their lab stations. By reducing the pressure in the microscale bell jar, they can expand a balloon, boil water, and even transfer liquids from one pipet to another. They can watch a marshmallow or shaving cream increase in volume as the pressure is reduced and learn about how extremely low pressure affects the world around them. Instead of passively observing a demonstration, students can actively experiment on their own and observe the results right before their eyes. More advanced high school and college level students can study Boyle's and Raoult's Laws and finally understand the relationship between vapor pressure, temperature, and boiling point. Included with the full instructions and guide is a bonus set of Educational Innovations ideas to challenge you and your students. Kit includes 8.5 cm (3.5") bell jar, base plate, vacuum pump syringe, suction cup, balloons, pipets, instructions, and Ron Perkins' Thirteen Open-Ended Challenges. Also Available: GAS-145
These smaller 30 ml syringes are perfect for use with our Microscale Vacuum Apparatus (VAC-10) or Basic Gas Collecting Kit (GAS-300), especially for students with limited hand strength. It will take more strokes to achieve the same results as the 60 ml syringes, but these syringes provide greater control with less effort.
