How might I use these?

Great for forming a tight "lid" on test tubes. Makes an airtight seal to prevent contamination if you want to prevent gases entering. Also reduces the risk of spills when working with young children!


Specification:

Rubber

To fit 13mm test tubes (as sold in the Laboratory Starter Set)

Base measures 13mm, top 16mm, length 24mm


Supplied:

Five solid rubber bungs


What goes well with these?

Laboratory Starter Set

Online STEM! (Small group STEM tuition online)


Top tips!

Wash in hot soapy water. Store dry.

If your experiment produces gas you may want to allow the gas to escape! (Unless you want to see how far you can launch the rubber bung, in which case Safety specs may be a good idea)!!
