The filrstcolor-accurate

module 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 exclusive

photoelectronic system includesthrough-the-lens auto exposurecontrol (from 32 min. to 1/100seconds with any film that you

can name) plus through-the-lenscolor temperature metering andmatching.

_ And when we say any fl m,we mean it: a choice of modularbacks and accessories lets youshoot anything from 35mm (withautomatic film 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 it

even includes an inexpen-sive body without automaticfeatures-but with the samewide choice of interchange-able backsand 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 or

black and white.Send for our free lit-

erature, and you'll see justwhat we mean.

If your research involves DNA-RNA,or DNA-DNA Hybridization studies, NBS has the answer. A UniversalMembrane Filtration Apparatus, equipped with reversible washingassembly and individual reservoirs, can now be employed for hybrid-ization studies as well as rapid and complete filtration and/or collec-tion of bacteria and precipitates; and protein-DNA-binding studies.To eliminate handling of individual reservoirs, a 10-cavity loadingblock can be quickly set in place for efficient filling and filtration.The entire battery of filters, clamped and sealed together, can beinverted at one time so that both sides of the 25 mm membranescan be repeatedly washed.
