Posslble adaptatlons The main advantages of this atomizer are that the amount of chemicals needed for the experiment is reduced and that this experiment can be prepackaged for student use in the future. This atomizer could also be used in simple chromatography work. BRO.ERIC HENDERSON Emhop Walsh H S Cumberland, MD 21502
Safety Inserter Tips Supplier: S17 Science Supplies and Services Co., LTD P.O. Box 1591 Kingston, Ontario, Canada K7L 5C8 Price: $9.80 (Canadian)for a set of 8 tips
This set of eight plastic tips fits most of the "cork borers" that are generally found in a lab. The tips fit the end of the borers, allowing for the insertion of glass tubing. Suggested uses These tips can be used to convert a set of cork borers into a set of instruments for the safe insertion of glass tubing and thermometers. This leak-proof and break-resistant atomizer consists of a rubber squeeze bulb and a plastic noncorrosive atomizer tip; the bulb is replaceable. Suggested uses Dilute solutions of chemicals used for flame tests can be loaded into the atomizer and then sprayed into the flame. It produces a very fine spray, which saves on chemicals and produces a consistent, reliable flame test.

Possible adaptationslcomments After receiving these tips in the mail, I used them as described and found that they make glass insertion amazingly easy. The tips come in all necessary sizes (the largest I'll never use). Since the cost of thermometers is high, these tips will be a worthwhile investment. IRWIN TALESNICK Queen'sUnlverslty Kingston.
