Since 1955, Cole-Parmer has been a leading global source of laboratory and industrial fluid handling products, instrumentation, equipment, and supplies.
Fields – temperature measurement and control, electrochemistry, and fluid handling.
Water Baths offer the versatility needed to handle virtually any laboratory procedure including: incubation, inactivation, and agglutination, as well as most pharmaceutical, serological, biomedical, and industrial procedures.
The company, founded in 1946 by Joseph F. Keithley in a Cleveland, Ohio, workshop, designs, develops, manufactures and markets complex electronic instruments and systems geared to the specialized needs of electronics manufacturers for high-performance production testing, process monitoring, product development and research. Now part of Tektronix.
In September, 2010, the company agreed to sell itself to the Danaher Corporation, a Washington, D.C.-based conglomerate, for $21.60 per share. It was soon merged with Tektronix, Inc, which had been acquired by Danaher in 2007, and now exists wholly as a brand of Tektronix.

Specialized Research Instruments for pulse, signal, light and function generators. Berkeley Nucleonics Corp – BNC is a leading manufacturer of precision electronic instrumentation for test, measurement and nuclear research.
A random pulse generator that utilizes a charge control concept. Controlled voltage transitions at average rates from 10 Hz to 1 MHz.
Besides random pulse, the Model DB-2 also provides mono energetic repetitive pulses. In this mode, the DB-2 is an excellent general purpose pulser. When the EXT REF input is used with an external ramp, the DB-2 provides sliding pulses to quickly check system or component linearity.

A Benchtop Design with Easy Programming Interface. Cost-effective yet highly flexible and functional approach for your synchronization and timing needs. Modes: burst, duty cycle, continuous, single shot, channel multiplexing.
Lake Shore Cryotronics, Inc. is an international leader in developing innovative measurement and control solutions. Their products include sensors for cryogenic temperature and magnetic measurements as well as systems for the magnetic and electronic characterization of materials.
The Model 372 provides the best possible temperature measurement and control capabilities for dilution refrigerators (DRs) that are intended to be operated below 100 mK. The Model 372 makes it easy to perform multiple tasks that were once very difficult to perform reliably at ultra-low temperatures:
Measure a wide range of resistive devices – With up to 22 different current (I) excitation levels available, the Model 372 is able to perform accurate impedance measurements from several microohms (10-6 Ω) to many megohms (106 Ω), all while keeping power dissipation levels to an absolute minimum.
