; Ρ Ί«Ε?0 COLORIMETER
This low-cost "production tool" makes it easier than ever to get quick, dependab le pho tomet r i c readings. In many industrial laboratories it is the basic equipment for quality control testing, inspection . . . even research! In others it handles all routine work, taking the load off expensive, special-purpose equipment. • DEPENDABLE ACCURACY! Narrow band
pass (only 20 m/i! ) assures highest spectral purity.
• EASIEST TO USE! Dial inscantly sets Certiiied-Precision diffraction grating to desired wavelength; no color filters to fuss with.
• FASTEST READINGS! Instant-acting meter gives exact percent transmission, or optical density.
• LOW PRICE, DOUBLE VALUE! Colorimeter plus spectrophotometer 365m/i-950m/t range in one long-life, trouble-free instrument. (Extended range, 340m/£-950m/i at slight extra cost.)

Elemental Nuclear chemists working on spent
fuel element processing (page 2690) have come up with wha t they call a new synthetic "element." Because it is not always advantageous to try pyr©metallurgical processes on real reactor fuel elements, researchers resort to compounding their own synthetic mixtures b y tossing in bits of uranium, plutonium, barium, cesiu ., strontium, and any other "rums" tha t may be needed. T o the initiate, this synthetic mixture is known, appropriately enough, as "fissium/'
Invention's Rewards After publishing a picture of the
Quickfit & Quartz "vest pocket" chemical lab (C&EN, March 19, page 1362), w e learn from Jobn T. Stock of the University of Connecticut that this apparatus was developed from a design h e and M. A. Fill worked out while Stock taught at Norwood Technical College in London.
Vest pocket prototype
"Messrs. Quickfit ^ Quartz saw our prototype at the L^52 International Congress on Analytical Chemistry," Stock adds, "and asked our help in producing a commercial model. With their technical department, we spent several hundred houars in drafting, testing, and rebuilding: until a suitable production form wast evolved.
"Since we had mo direct financial arrangement with thte company, when they wished to reirrahurse us w e suggested they endow I^orwood's student fund so tha t our stucdents could benefit from our work. The firm readily agreed to this. The perpetual endowment provides an arward for the best chemistry student of the year / '
One of the units n o w is o n permanent exhibition in the crjLemistry section of the London Science Museixm, Stock informs us, and the equipment has been used, also, in a film made by BBC for television showing. Two other British firms also are marketing microchemical apparatus developed by Stock and his colleagues.
Challenge for Plastics - New York's Boarcd 'of Education has been looking for a n e w type of window for its schools, at ILeast for the lower floors where panes are frequently broken b y students who take a rather dim view of edhication. Various plastic windows have been tried. But though they won't shatter, all used so far have shown a tendency to cloud or scratch easily. However , the board has hopes that a monscratching, non-clouding pane will f>e developed, sooner or later.
