17x150mm Polystyrene Test Tubes w/Caps: Pack of 250

This is a case of 250 new, clear polystyrene (plastic), non-graduated 17mm (17OD & 14ID) x 150 mm (approximately 6 inch) test tubes.

The test tubes have a liquid storing capacity of up to 20ml .

They are non-sterile and come with a translucent Flange Cap, which insures a good tight fit.

These precision-molded test tubes are ideal for a wide range of laboratory applications.

They are made of a clear plastic resin, thus preventing the problem of broken glass.

Since polystyrene is not as hard as glass, however, it can scratch easily, especially during shipping.

This will not affect the use of the tubes, however.

So please be aware that your tubes may have some minor scratches or scuffing that should not show when filled.
