Test tubes, culture tubes, there doesn't seem to be a standard term for these standbys of every lab. The plastic tubes are 10 mm in dia. and 75 mm long. The glass are all flint, which means you cannot put them over a flame or heat anything in them. The assortment of glass tubes is from 10 to 14 mm dia x 50 to 100 mm long. We'll give you the best mix that our supplies can produce. Chances are you'll get all of one size in each order.
