FEATURES Continuously measures turbidity of liq­

uid streams by light absorption and scattering; patented bolometer senses changes in transmitted radiation and records directly in Jackson candle units; remote multipen recorder ac­cepts four readings from different lo­cations

Solid-state vibrating reed electrometer has sensitivity of lCh17 amp.; used to measure very small currents such as the Hall effect in organic and inor­ganic semiconductors, photoconduc-tors; used to study piezoelectric, ther­moelectric, and electrochemical prop­erties

Solid-state unit provides variable direct-current power from 1000 to 5000 volts; designed for control of single or dual evaporation

Dual potential control channels allow in­stantaneous shifts between potentials; 10-amp. and 10-volt output; potential stability of ±0.5 mv./24 hours

Power-loss measuring and sorting instru­ment is useful in making rapid metal­lurgical tests; 360 cycles per second

Versatile analog computer and acces­sories can program most electro-metric and photometric instruments

Portable, high-precision instrument use­ful in determining optical activity in sugars, amino acids, steroids, and other substances; interchangeable measuring caps; spiral focusing

Series of infrared, noncontact pyrom­eters have temperature sensors, am­plification electronics, and instrument controls housed in single units; vari­ous models cover temperature range from 70° to 2500° F.

Operates as ice mantle drop calorimeter to determine specific heats of metals, ceramics, glasses, plastics, and cer­mets to 3000° F.; chiller unit lowers range to - 3 0 0 ° F.

Sensing probe and recorder measure the frequency and amplitude of vibrations in processing equipment

Laboratory beakers, crucibles, boats, fritted filters, and other items have outstanding corrosion and tempera­ture resistance; material is electrically conductive; engineering applications include dip pipes, thermometer pock­ets, relay contacts, and specialty equipment

Unit continuously strip packages small fittings in polyethylene bags; rapid loading and sealing

Tough-to-peel vinyl on steel New Versalon®1140 polyamide resin promotes togetherness

GENERAL MILLS

CHEMICALS

Versalon 1140 polyamide resin is a hot one! Not just a warmed over version of older hot melt adhesives. This new one has unmatched adhesion to highly plasticized vinyl. In fact, peel strength tests of vinyl to steel bonds result in failure of the vinyl substrate rather than the Versalon 1140 bond. Versalon 1140 adheres equally wel l to metals, fabrics, rubber, glass, leather, or rigid or flexible plastics ( including diff icult-to-adhere ABS! ) . It is already being used successfully as an adhesive for decorative laminates, panels and upholstery in the automotive industry. Because of its elongation of 900%, Versalon 1140 maintains its high flexibility and shock resistance at temperatures far below zero. The resin can be used as a hot melt, or from solut ion, or as extruded film with heat activation. It has extreme­ly good wett ing characteristics, long open time, and good hot tack to permit easy assembly with mild pressure. You can' t afford to pass up th is great new adhesive!
