I'm selling test tubes that you'll need for JC Bio and Chem labs and SPA.
Selling a bunch of 13 *normal sized test tubes plus 3 *small test tubes for a total of $5.
If that's too many, you could buy 6 normal sized test tubes for $3.
* Normal sized test tube: 15cm tall and approx 1.3cm inner diameter (standard). NOT boiling tubes.
* Small test tube: 10cm tall and approx 1cm inner diameter (faster test for gases in organic chem)
