color-accuratephotomicrographicmodule system.

!.....@:.The PM-10 photomicrographicsystem from Olympus is the firstmodular camera system that notonly delivers accurate exposure,but accurate color, too.

That's because its exclusivephotoelectronic system includesthrough-the-lens auto exposurecontrol (from 32 min. to 1/ 100seconds with any film that youcan name) plus through-the-lenscolor temperature metering andmnatching.

And when we say any film,we mean it: a choice of modularbacks and accessories lets youshoot anything from 35mm (withautomatic fi Im advance, if de-sired), to Polaroid film packs, to

4x5" (plates, film packs,~ sheetsand Polaroid sheets).

In fact, our choice ofmodules is so wide that iteven includes an inexpen-sive body without automaticfeatures-but with the samewide choice of interchange-able backs and accessories.

Whatever you're look-ing at now, whatever micro-scope you're using, there'sa PM-10 system that cancapture just what you seethe way you see it-color orblack and white.

Send for our free lit-erature, and you'll see justwhat we mean.

Recording Titration System

The Titrigraph (Fig. 1) automaticallyrecords standard titration curves, 'firstderivative curves, or the kinetics ofreaction solutions. A digital or analogpH meter may be used as the signalsource; sensors include pH, specific-ion, or other potentiometric electrodes.The amount of reagent dispensed iscontrolled as the speed of the reactionchanges. London Company. Circle No.867 on Readers' Service Card.

Enzymes

More than 150 purified enzymes arenow available from a single supplier.Among them are choline kinase, ob-tained from rabbit brain, which is use-ful in measuring content of choline andacetylcholine in brain tissues; lacto-peroxidase, obtained from milk, whichfinds application in studies of peroxi-dase-dependent reactions; and super-

oxide dismutase, obtained from beeferythrocytes, which facilitates the studyof free radical reactions. Research Di-vision, Miles Laboratories. Circle No.865 on Readers' Service Card.

Animal Activity Monitor

The Varimex activity meter dis-tinguishes between vertical movementand horizontal movement of sub-jects. Experimental animals and con-trol animals may be monitored alterna-tively by the same control unit. Thecontrol unit houses signal oscillators,timing and tuning devices, sensitivityadjustment, and accumulating counters.Sensors of horizontal movement are in-ductive; sensors of vertical movementare capacitive. Systems may be de-signed to monitor movement under avariety of experimental conditions.Columbus Instruments Division of In-ternational Instrument Company. Cir-cle No. 868 on Readers' Service Card.

A little somethingfor nothing.

The NalgeneR Hand-Operated Vac-uum Pump puts controllable vac-uum in the palm of your hand.Weighing less than 1/2 pound, it at-tains a vacuum up to 25 in. Hg witha few easy squeezes of the handle-and can hold it for 24 hours! Youmonitor the exact vacuum on thegauge, calibrated in both centime-ters and inches. Pumping rate is15cc (one cubic inch) per stroke.Will also generate 7 psi positivepressure through tubing connectedto the exhaust port. An integral

valve allows releasing or adjustingvacuum without disconnecting thepump from the line.This rugged, versatile vacuum

pump will have many uses inschools, hospitals, laboratories, andin the field. Specify Nalgene No.6130. An economy model, identicalbut without the gauge, is also avail-able (Cat. No. 6131).

Olympic medalists we ain't.But our Technical Specialists havehad uncommon training, too.

Looks difficult, doesn't it? And it is.You had better know every technical detailabout the capabilities and applications ofyour equipment from the tips of your skisto the bindings that hold your boots. That'swhere our S/P Technical Specialists havevery common ground with the uncommontraining of Olympic ski jumping medalists.

Our 39 S/P Technical Specialists are in aclass by themselves. They are concernedwith very expensive, very technical, verysophisticated, very uncommon equipment.And it's their job to evaluate your needs,then to translate the capabilities andapplications of this complex equipment intocommon sense terms to help you. That's whywe train them right at the manufacturer'splant. So they will know as much about theequipment as the engineers who built it.

So before you jump to a conclusion, talkto our uncommon S/P Technical Specialist.He'll make a lot of common sense to you.
