You can maintain accurate, rigid control over important opera tions by making on-the-spot tests with Taylor sets in just minutes. No experience necessary. No fragile individual glass standards to handle. OU The color standards in a 0 T* Taylor Comparator — used for 21 years in the field — have been certified by an independent laboratory as true and still abso lutely accurate.

Reduces W feed to as fine as 10 mesh in single pass. High capacity, low power consumption.
Filters for vacuum or pressure can be supplied in 12 different models. " M i crocell" filters have three types of disks: for absorption, adsorption, and ultrafiltration. Pore sizes range from 6 microns to 3 millimicrons. All can be used interchangeably and can be autoclaved. Models that can with stand pressures up to 1000 p.s.i.; models with heating jackets; and models with Teflon liners are avail able. Scientific Glass Apparatus Co., Inc., Bloomfield, N. J . 422
Gy-Rotary Laboratory Ball Mill For wet or dry grinding; batch or continuous operation. The grinding chamber, 12" diameter by 3Vt" deep, does not rotate, but travels in a circular path of small radius. The grinding balls bombard each other from all directions in small spheres or zones of activity.

ANALYTICAL CHEMISTRY
The Series 5000 Selecta-System Gas Chromatograph provides versatility in the selection of components. Typical systems available include those using electron attachment detectors, high temperature flame detectors, argon de tectors, and thermal conductivity de tectors. A range of power supplies, column baths, column temperature controllers, and recorders are available to be compatible with the working system chosen. The selection of the detector system is the starting point. Accessories include an electronic inte grator, disk integrator, gas sampling valve, microliter syringes, and multispeed chart drive. A six-page bulletin describes the units available. BarberColman Co., Rockford, 111. 423
