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 warm 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.

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.
Suggested Science Idea(s)
Students can use the Microscale Vacuum Apparatus to test a variety of materials; plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
Students can use the Microscale Vacuum Apparatus to plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.
Students can use the Microscale Vacuum Apparatus in an investigation and develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.
Students can use the Microscale Vacuum Apparatus to plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
Students can use the Microscale Vacuum Apparatus to test and evaluate design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
Students can use the Microscale Vacuum Apparatus to test and design a solution to complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
Students can use the Microscale Vacuum Apparatus to experiment and investigate the effects of the vacuum or fluctuations of air pressure on solids, liquids, and gases.
Place shaving cream in the apparatus and evacuate the air. Then return the air and make observations. Use a variety of materials to classify them.
Observe the Microscale Vacuum Apparatus in action. What purpose does it serve? Design, construct and test your own apparatus that solves a real world problem.
