Gas syringe figures for collecting gas

Gas Syringe draws a 50 or 100 cm³ glass gas syringe lying on its side, with the plunger pushed out to the volume of gas you type. Students read the volume at the plunger’s flat face, to 0.1 cm³, one digit past its 1 cm³ marks.

Show the syringe alone, or set up to collect gas from a reaction: a conical flask with a bung and delivery tube, a rubber sleeve joining the tube to the nozzle, and a stand clamping the barrel. Teachers use it for rate of reaction questions, where students read the volume of gas collected, and for questions on reading lab apparatus.

What you can set

  • The syringe alone, or set up with a conical flask, delivery tube and stand
  • Size: 50 or 100, with the scale in cm³ or mL
  • The volume of gas, typed or picked at random
  • A magnifier above the syringe or in place of it, spanning 1 to 6 numbered marks
  • A chart title, and an answer key line with the volume

Copying, printing and sharing

Copy the figure straight into a test, worksheet or slide, or download it as a PNG or SVG. Printing the page prints just the figure. Share link copies the page’s address with your settings in it, so anyone who opens it sees this exact figure, and presets save settings you use often in your browser. It’s free, with no sign-up.

Frequently asked questions

How do you read a gas syringe?

Read the scale at the flat face of the plunger, the end nearest the nozzle, not at its knob. The syringe is marked every 1 cm³ and numbered every 10, so read to the last mark and estimate one more digit, like 37.4 cm³.

Should the scale be in cm³ or mL?

Either: 1 cm³ is the same as 1 mL, so changing the unit relabels the scale without changing the reading. Pick whichever your course uses.

Why do the 50 and 100 cm³ syringes look the same length?

Both are drawn the same length so the scale stays easy to read; the 50 cm³ syringe is drawn thinner.

Can I show the syringe connected to a reaction flask?

Yes. Choose the setup under Syringe to draw a conical flask of liquid with a bung and delivery tube, a rubber sleeve joining the tube to the syringe’s nozzle, and a stand clamping the barrel.
