If you're looking for economical weighing, look at the Mettler electronic top-loading balances. The no-frill PB models are best for people who want fast, accurate weighing but do not require digital outputs and other extra features. They're ideal for routine weight determinations and checkweighing. Just place the sample on the pan and read the 7-segment digital result. .For non-routine weighings, a Mettler PL model should be your choice. Some PL balances are avail able with a Net Total Display feature that gives you a separate display of intermediate net totals when weighing in formulas. Or you can also get a digital output for connection to peripheral equipment, such as a calculating printer. All PL balances can easily adapt to less-than-perfect weighing envi ronments because they have an external switch to adjust integration time.

For Your Information The efforts to save the Mediterra nean Sea from pollution get help from an analytical instrument, the atomic absorption spectrometer manufactured by Varian Techtron Pty Ltd. of Australia. In a study coordi nated by the United Nation's Envi ronment Program, the Mediterranean coastal nations use the atomic absorp tion spectrometers to identify the presence and amount of metals such as mercury and cadmium in the sea. The spectrometers with carbon rod at omizers have so far been ordered for laboratories in Malta, Tunisia, Tur key, Israel, Yugoslavia, Cyprus, Alge ria, Egypt, and Spain. The American Society for Testing and Materials (ASTM) announces publication of a new quarterly enti tled Geotechnical Testing Journal. Topics to be covered include: new testing equipment, apparatus, and procedures for both field and labora tory applications; test results that give insight into procedures and tech niques; and test procedures related to
News highway materials and geophysical exploration. T h e first issue was p u b lished in March 1978. Subscription prices are $15 for A S T M members and $30 for nonmembers.

Founded in 1975 with a staff of two, it has now expanded into 5 000 sq ft of modern laboratory space with a staff of 11. T h e services offered are: trace metal analysis; cosmetic, flavor, fragrance, a n d food analysis; analysis of organic compounds such as paint a n d pesticides, environmental testing; plating b a t h analysis, etc. For more information on the types of services and schedule of testing fees, contact: Princeton Testing Laboratory, Princeton Service Center, U.S. Route 1, Princeton, N.J. 08540 (609-452-9050).

See how easy weighing t o a millionth of a grant can be w i t h t h e new M e t t l e r microbalance·
The new Mettler ME30 electronic microbalance brings pushbutton ease to accurate weighing in the micro range. Use it for elemental analysis, filter weighing or whenever minute samples are involved. Sensitivity and linearity are constant over the entire weighing range. Built-in tare weights up to 990 mg can be used to supplement the electrical weighing range of 0-30 mg. One pushbutton resets the digital display to zero, and another brakes the weighing pan. Weighing results are delivered in seconds, and can be transferred automatically to a connected calculator or printer. The Mettler ME30 makes it all so easy.
