 HI 2210 pH Meter

HI 2210 pH Meter

Cambridge ID #: 23330
  • Simple User Interface
  • Operation is simple with limited features that only require the use of a couple of buttons. Readings are easy to view on the large, clear display.
  • One or Two-Point Calibration
  • Automatic calibration can be performed at 1 or 2 points using the 5 preprogrammed buffers (4.01, 6.86, 7.01, 9.18, and 10.01).
  • HI1131B pH Electrode
  • The HI2210 is supplied with the HI1131B glass body, double junction, refillable pH electrode with an indicating sensor made of High Temperature (HT) glass. The double junction and HT glass design allows the HI1131B to be used in a wide variety of application from samples with metals and Tris buffer to samples at elevated temperatures.
  • Temperature Compensation
  • The HI2210 offers automatic or manual temperature compensation of pH measurements over a wide range from -9.9 to 120.0°C.
  • Stability Indicator
  • The HI2210 features a stability indicator. An hourglass appears on the display when there is instability in the reading. The hourglass disappears once the reading has stabilized. At that time a reading should be taken or stored.
  • Measurement Recall
  • The HI2210 has a "œMEM" button to store a reading. The reading can be recalled at anytime by pressing the memory recall "œMR" button.

     HI 2550 pH Meter

    HI 2550 pH Meter

    Cambridge ID #: 22452

    The HI2550 is a rugged and highly accurate multiparameter benchtop meter that measures pH/ORP, EC/TDS/Salinity, and temperature with a clear LCD display, data logging capability, and USB port for computer connectivity.

    The HI2550 is a dual channel meter that allows for measurement of pH and ORPE on one channel and EC, TDS, and salinity, on the other. Readings for pH and EC can be manually or automatically compensated for temperature variations with the separate HI7662 temperature probe or from the built-in temperature sensor of the conductivity probe on channel two.

    As a pH meter, the HI2550 can be calibrated up to five points with a choice of seven standard buffers or two custom buffers. As an EC/TDS/Salinity meter, the HI2550 can be calibrated at one point for offset and at one point for slope with a choice of six conductivity standards. The % NaCl is calibrated to a single point at 100% with the optional HI7037 salinity standard. The calibration data including date, time, standards used, offset, slope, cell constant, and cell factor can be accessed at any time by pressing the dedicated GLP button.

    Parker NitroFlow Lab Nitrogen Generator

    Parker NitroFlow Lab Nitrogen Generator

    Cambridge ID #: 22488

    The Parker Balston® LC-MS NitroFlow Lab is a self-contained membrane nitrogen generator that produces LC-MS grade nitrogen with output pressure to 116 psig. Nitrogen is produced by utilizing a combination of compressors, care¬fully matched with filtration, and membrane separation technology components. Intake ambient air from the labora¬tory is filtered using an inlet suction breather filter to remove airborne organic and particulate impurities. This purified air is delivered to a long life low pressure air compressor which provides an air stream to hollow fiber membranes which subsequently separate the clean air into a concentrated nitrogen retentate and oxygen enriched permeate, which is then cycled through the system. Prior to exiting the system pure nitrogen retentate is delivered to a nitrogen amplification compressor to assure proper pressure, flow and purity to the LC-MS. The Parker Balston LC-MS NitroFlow Lab will deliver a continuous or on demand supply of pure nitrogen making it the smart alternative to cylinders. Superior engineering with carefully matched filtration, membrane separation and compression technologies have resulted in a system with the utmost reliability and longevity. Additional applications include: nebulizer gases, chemical and solvent evaporation, instrument supply and purge, evaporative light scattering equipment and sparging.

    Specifications:

    • Flow capacity to 32 LPM
    • Includes 2 year compressor warranty
    • Ideal for all derivatives of ESi and APCi modes
    • Includes state-of-the-art, oil-less compressors
    • Unlike PSA Hosmer technologies, membrane will not suppress corona needle discharge
    • Special sound insulation design ensures quiet operation
    • Weight: 200lbs
    • Dimensions (H x W x D) [in]: 27.6 x 35.4 x 12.2

    Millipore SA 67120 Water Purification

    Millipore SA 67120 Water Purification

    Cambridge ID #: 22267
  • The Millipore Milli-Q Synthesis A-10 water purification system delivers type 1, ultrapure water for your applications thatÂ’s pyrogen and RNase free. Applications such as ELISA tests, electrophoresis gel make-up and serum-based cell and tissue culture media perpetration, affinity chromatography, and protein and nucleic acid isolation. The Synthesis system takes pretreated water (either through EDI, Reverse Osmosis, Distillation or Deionization, and pumps it through the Q-Guard cartridge, then passes the water under UV lights at two wavelengths, 185 and 254nm. Organic compounds are oxidized and bacteria is destroyed. The Quantum cartridge then filters out the trace ions and oxidation by products. Purified water is then sent through an ultrafiltration module, and finally through a filter membrane that removes any particles or bacteria greater than 0.22µm in size.
  • The Millipore Milli-q Synthesis A-10 includes a built in A-10 total organic carbon (TOC) monitor, high-precision resistivity meter, while providing complete monitoring of water quality throughout the process. As the process proceeds, the water quality and operation data is recorded in system memory. This Millipore water filter uses a backlit display to show resistivity and TOC Levels in addition to other system functions, for easy monitoring.
  • The Millipore Milli-q Synthesis A-10 has a flowrate of up to 1 liter per minute.
