Proven reliabilityv in

top performance power supplies

Top performance is easy to confirm-just testan instrument when you get it to verify its

specifications. (Several popular brands will flunk!)Reliability is harder to quantify, but of the thou-sands of power supplies we've built over the lasttwenty years, only about 1% have come back forrepair during their entire three-year warranty.

Constant power. Just set power, current, andvoltage limits and the power supply aiitomaticallycrosses over from one parameter to the other asconditions change in the geL Isco was the first todevelop electrophoresis power supplies withcontinuous constant power for faster separationand sharper zones.

Programmability. The 4000 V Model 595 isthe most versatile power supply for any exacting

experiment, including nucleic acidsequencing andelectrofocusing You can program three differentsets ofvoltage, current, andpower limits for a singlerun, automatically switching from one set to thenext according to time, accumulated volt-hours, orrate of hange in gel current indicating the electro-phoretic endpoint.Safety. All four models are built with specialemphasis on safety as weli as reliability. They aredesigned to meet EEC high-voltage safety recom-mendations regarding insulation, air gaps, andother design parameters. Components listed by UlICSA, and VDE are used wherever possible. Anti-condensation heaters protect internal circuitsagainst high coldroom humidity. Models 494 and595 have a unique Isco ground fault detector thatwarns ofdangerous conditions even at zero outputvoltage, so you can check for a defect before youturn on the power.

Value. Best of alL Isco quality doesn't cost more.We'll always give you better instruments for yourmoney. So before you buy a power supply, give us atoll-free call. We'll send you our free 80-pagecatalog of instruments for electrophoresis andliquid chromatography right away.
