C-60HL... the extra feature NMR that stands alone in its class Even if you could find a 60 MHz NMR which would give you

the guaranteed performance which is inherent in the C-60HL—

you positively would not find these features available:

/ Both external and internal lock - built in

*- Wide sweep wi th single sideband for other nuclei - built in

« S/N Booster - a built-in computer for sensitivity enhance

ment (optional)

•* Noise-modulated, multi-mode, heteronuclear spin decoupler

* Homonuclear spin decoupler - built in

These are the "extra" features which make the C-60HL so popular today. Send for your brochure, now.

The direct reading range of the LECO WR-12 Wide Range Carbon Determinator is 3.5% to less than 0.01% for a one-gram sample. Accuracy is ± .002% C or ± 1% C present, whichever is greater. Pre-se-lection of a suitable range is not required and one-point calibration is acceptable for most carbon values. The WR-12 is completely automatic and percent carbon is read directly from the digital display for all carbon ranges. The use of a molecular sieve to adsorb the CO2 makes plant as well as bottled oxygen entirely satisfactory. The WR-12 has applications in ferrous and non-ferrous industries.. .wherever rapid, accurate carbon determinations are needed. It is ideally suited for the BOF steel making process.

NOW... FROM CABOT FLAME RESEARCH

Al203 An oxide with exciting possibilities — What can it do for your product? The unique properties of positive surface charge, large surface area, high purity and extremely small particle size make ALON a versatile and exciting new material with potential uses in many diverse industries. A fumed alumina of different crystalline forms consisting predominantly of the gamma modification, ALON is made by the hydrolysis of aluminum chloride in a flame process similar to that for making Cabot fumed silica, CAB-O-SIL®.

ALON is an inorganic oxide with a surface charge that remains positive up to a pH level of 9.1, the isoelectric point. Each gram of ALON has a surface area of 100 square meters. This produces high functional activity from relatively small quantities.

SUGGESTED USES FOR ALON TEXTILES — As a wool spinning aid, ALON has been found to considerably lessen end breakage and " f ly . " ALON substantially increases yarn breaking strength, permits the use of shorter stocks and higher productivity with less waste. The ALON particles form a strong bond with the negatively charged wool fibers, making them less susceptible to pulling apart. The same function is under investigation in cotton and synthetic fiber spinning.

Its positive charge indicates ALON potential as an anti-static, anti-soiling and anti-pilling agent for synthetic fibers and blends. This same property may promote dyeability in certain hard-to-dye fibers.

PAPER — Paper machine down-time is reduced when ALON is used as a de-sliming agent. The positive surface charge helps control build-up and deposition of pitch on rollers, and keeps agglomerates from depositing on the paper thereby improving quality. The high purity and good electrical properties make ALON an effective filler in specialty electronic capacitance papers. OTHER USES FERRITES — ALON improves cold temperature operation of ferrites used as armature cores in fractional hp motors.

LIGHT TRANSMISSION AID — ALON is suggested as an additive to phosphor coatings in fluorescent or cathode ray tubes to improve the light output on aging and where high efficiency light transmission is desired on incandescent bulbs. COSMETICS — Hair sprays may be improved by ALON because the positive surface charge reacts with negatively charged hair fibers.

ELASTOMER REINFORCEMENT — ALON has demonstrated an ability to increase creep strength and reinforcement of adhesives and such elastomers as SBR, butyl, nitrile and neoprene rubbers. THICKENING AGENT—Its positive surface charge suggests ALON can be combined with CAB-O-SIL fumed silica to thicken polar liquids such as water. CERAMIC BODY — ALON can be used to improve strength and electrical properties. AIR POLLUTION CONTROL — ALON is being considered as an additive in fuel oils to reduce contaminant emission and minimize scale build-up on furnace firewalls and boiler tubes. HYDROPHILIC AGENT — ALON can be applied to normally hydrophobic surfaces such as plastic films and fibers, photographic films and offset printing plates to improve wettability and eliminate water spotting.

There is something new under the sun in automated S02 analysis. The new compact portable S02 Monitor from Technicon*

Now, Technicon offers a completely automatic, wet-chemical system for monitoring ambient S02 using the officially accepted West-Gaeke procedure. The system will operate without human attention for great lengths of time, and features low reagent consumption techniques and a new gas absorption system.

Now infrared can be on every bench.

With the new Model 700 Infrared Spectrophotometer, you can afford to put infrared on every laboratory bench—wherever you want it — everywhere you need it. Universities and colleges, industrial research and control laboratories have been ordering the 700, not just one instrument at a time, but in multiples.

The Model 700 is leading an infrared revolution in today's laboratories. Suddenly—at a price of $3000-infrared's within the reach

of everyone. The Model 700 is a quality instrument, built to Perkin-Elmer's exacting standards. It offers a grating monochromator for good resolution, clean unbroken chart presentation, linear frequency recording, and operates in the most informative region of the spectrum -from 4,000-650 cm'1 (2.5 to 15.4 microns). It has push-button simplicity, compactness and reliability.

Interested in this newest addition to the world's broadest line of IR spectrophotometers? Write for our

informative brochure on the Model 700 or for one of our applications studies. We can show you practical uses in polymers and plastics, paints and coatings, packaging and containers, waxes, forensic science, and biomedical and educational areas.

POLISHES WATER

TO A CUSTOM

FINISH IWT "polished", water has the last motes of color, iron, gases, minerals, and guilty feelings removed to leave only concentrated sparkle.

But only if you want it that way! Not everyone wants or needs water that good and it costs extra money to treat it to that quality. IWT understands your need for economy and designs water treatment systems to fit your needs. Treatment is carried to the economical point-of-no-return.

When IWT engineers a water system for you, the water is just as good as it should be.

PHASE SEPARATING

The world's first, fast-acting, disposable separatory funnel

Whatman No. 1 PS is a water repellent paper that acts as a phase separator in place of conventional separatory funnels... separates aqueous solutions from water immiscible solutions, quickly and conveniently. Because it's hydrophobic, No. 1 PS retains the aqueous layer while allowing the organic layer to go through... filters out any solid that may be present at the time of filtration... and, because it's paper, it's disposable.

No. 1 PS makes prior separation of the phases In a separatory funnel completely unnecessary... saves considerable time and effort in solvent extraction. It gives a complete and rapid quantitative separation of the two liquid phases. There is no loss of materials as with ordinary separatory funnels. Can be used with organic solvents that are lighter or heavier than water.

For further information, send for our free Phase Separating Paper Leaflet.

At last.

A laboratory reagent gas cylinder that stands alone. No racks, ring stands, brackets, or clamps.

When you buy Merck Laboratory Reagent Gases you get a quality product with three extras* Extra safety. Extra

convenience. Extra bench space. Extra safety because the cylinder is self-supporting, compact in size, and color-coded. Extra convenience because it handles like a standard reagent bottle but deJivers twice the volume of a lecture bottle. Reduces order and handling frequency 50%. Extra bench space because it's shorter than a lecture bottle, narrower than a sphere, and has no ring stand to take up room.

With all these extras in the cylinder, you could say we've introduced a new standard cylinder to the industry.

Besides ample stocks, your local Merck distributor also has something extra for you. A colorful, ready reference file containing 15 technical data sheets with actual-size reproductions of the cylinders. It's all free. Call him. He's expecting you.
