Beakers, student grade
Student grade beakers, heat resistant borosilicate glass, also known as "no-name" or "generic Pyrex". Same properties, lower price. Low form, with pouring spout, graduated for approximate measurement. Note how price increases dramatically with size. This is due simply to the fact that larger glass beakers break more easily. Therefore manufacturers, suppliers and distributors all take a bigger risk when handling and shipping these items, so the potential loss is "built in" to the price. Just because they are borosilicate glass doesn't mean they are unbreakable. All it takes is a little bump on the edge of a table to crack or break the larger beakers. Warning: Heating the larger beakers (1000 ml and up) can also be dangerous. If the larger beakers are not heated slowly and evenly, even though they are borosilicate glass, they will be more likely to break, potentially resulting in a huge mess and loss of whatever solution was in the beaker. So when heating these larger beakers it is best to increase the temperature gently and use a wide heating element or hot plate, NOT a small point source of heat like an alcohol burner, candle, bunsen burner or propane torch.

Flasks, Erlenmeyer (Rubber stoppers not included. Available separately.)
Student grade flasks, suitable for heating liquids. These are the flat bottom, "inverted cone" shaped ones. Borosilicate glass (basically "no name" Pyrex-type glass), narrow mouth, graduated for approximate measurement. Corresponding rubber stopper size and stock number shown in brackets. Depending on the supplier we use, the mouth of the flask may be slightly smaller or larger, so the corresponding rubber stopper size may be subject to change. Therefore, when ordering rubber stoppers to fit these flasks, please include a note to have us physically check that the rubber stopper fits the flask.

INDC.01 Blue Litmus Paper $2.95/vial
INDC.02 Red Litmus Paper $2.95/vial
pH Test Paper
While litmus paper (above) tells if substances are acidic or basic, pH paper tells you how strong those acids or bases are. OK, we used to sell this as the old orange paper strips, 100 per vial, but we have been told by our supplier that those strips are not very accurate, and that is why they were cheap (at least they were honest about it!). So we set out to find a better quality pH test strip, and found one. So now we have pH Test Strips, 3 pad type, wide pH range (1 to 14), 50 strips per pkg. These are MUCH more accurate than the old, single-colour orange pH test paper that we used to sell. Unfortunately, they are more expensive as well (26 cents per test). But hey, you get what you pay for.
INDC.14 pH Test Strips, 3 pad type, range 1 to 14 $14.95/pkg of 50
