The Thermo Scientific Orion Star A215 benchtop meter with kit displays pH and conductivity readings plus temperature on the large, backlit LCD display for pharmacology laboratory applications. The meter can display temperature with pH/mV/RmV on the first channel, or conductivity/TDS/salinity/resistivity on the second channel, or show all results at once. Electrode status, time, date, sample ID, user ID, and calibration points are also displayed with the measurements. The meter is designed for ease of use and reduced training requirements, with clear screen prompts, updateable soft keys, and an interface that supports English, Spanish, French, Italian, German, and Chinese. A pre-programmed auto-read function is available to lock stable readings on the screen, with an indicator alert that signals when the reading is stable. The meter can also be set for timed readings that gather data at specific time intervals. Non-volatile memory holds up to 2,000 data points with time and date stamp. Updates for meter software and complimentary data analysis software are available for download.The selectable cell constant allows use with two- or four-cell conductivity cells. Practical salinity or natural sea water curves can be selected for salinity readings. Linear or ISO/EN 27888 curves can be selected for total dissolved solids (TDS) readings. pH calibration is available up to five points, with automatic recognition for USA/NIST and DIN (Deutsches Institut für Normung) buffers. Conductivity calibration has selectable reading reference temperatures of 5, 10, 15, 20 or 25 degrees C with linear, non-linear, nLFu, or EP curve options. Errors can be fixed without a complete recalibration by using the calibration editing function.The meter has an IP 54 rating for limited ingress of dust and protection against water splashes. The device can be wall-mounted if table space is an issue. The electrode arm (included) can be attached to either side of the instrument. Meter input ports include Bayonet Neill-Concelman (BNC), reference pi...

The Thermo Scientific 4001-000 Genesys 20 visible-light spectrophotometer has a 325 to 1100mn wavelength range, spectral bandwidth of up to 8.0nm, and a tungsten-halogen lamp, and is used for routine testing and in teaching laboratories. The instrument provides direct measurement of routine absorbance, transmittance, and concentration data. The up to 8.0nm spectral bandwidth is used for routine quality control measurements when high resolution is not required. The tungsten-halogen lamp and single detector support routine measurements in the visible range. The spectrophotometer is compatible with 10mm square cuvettes. The two-line, 20-character LCD displays simple instructions and test results. A sealed keypad protects the instrument from spills. The instrument has RS-232 and 36-pin parallel ports for connection to a PC or printer (sold separately).

The Labomed Spectro 2000 RS single-beam visible-light spectrophotometer has a multi-cell receptacle to measure transmission, absorption, concentration, and factor for routine spectro-analysis in a range of applications and industries, including chemical, biochemical, agriculture, environmental protection, and education. The instrument has a 330 to 1,100nm wavelength range for use in the visible, near-ultraviolet, and near-infrared spectral range. It has a 0 to 125%T transmittance range, 0 to 1.999A absorption range, and 0 to 2,000C concentration range. The 6nm bandwidth provides more consistent results for low-concentration samples than does 1nm. It has a tungsten-halogen lamp, a silicon photodiode detector for reduced noise, and a monochromator with a 1,200 lines/mm grating mirror. A built-in stray-light filter increases accuracy. The instrument automatically calculates absorption, transmittance, factor, and concentration, and auto-zero and auto-calibration ensure consistent results. The spectrophotometer has a receptacle that accepts round test tubes and up to four 10 x 10mm square cuvettes. The two-line LCD provides access to controls and test results, and the capacitive-touch buttons ease cleaning and prevent liquids from entering the device. An RS-232C interface enables data to be transferred to a computer (sold separately). The included UV-VIS software provides data analysis and long-term records retention, and is compatible with Windows 95, 98, XP, and 7. The instrument has a switch that allows the customer to choose between 110VAC/60Hz and 240VAC/50 power sources.

These OxiTop automated BOD measurement systems provide a ready-to-use solution for both small and large laboratories. Choose the OxiTop IS system when a small number of tests need to be performed. Systems are available in 6- and 12-place configurations and include everything you need to begin testing. Convenient and simple to use - place the OxiTop measuring head directly on the BOD bottle containing the sample. The head senses pressure changes caused by cellular respiration within the closed system and converts that data into BOD values. The measurements are then stored in the imbedded memory for later retrieval. The included IS stirrer base maintains constant temperature and distributes oxygen evenly throughout the sample. Order the optional thermostat box to incubate samples at 20°C; the box measures 16-3/4"W x 14-3/4"H x 23-5/8"D (42.5 x 37.5 x 60 cm) and can accommodate an entire 12-place OxiTop system. OxiTop IS System uses the OxiTop measuring head with an LED display. The head automatically stores one value every 24 hours for five days. This system is best suited for fewer tests since programming and data recording must be done by hand. What's Included: OxiTop measuring heads, IS stirrer base (100/240 VAC, 50/60 Hz), amber glass bottles (510 mL), carbon dioxide absorbent, nitrification inhibitor, overflow flask, stir bars, stir bar remover, and batteries. Eliminate daily checks and increase data reliability with automated BOD testing Data is automatically stored in the measuring head Readings are given directly in mg/L Sample dilution is not required, saving you time AutoTemp function delays start of test until sample temperature stabilizes

Each stored method can be secured to any of three levels, including open access, read-only access, and password-protected personal methods. Post-measurement tools ensure that results are presented exactly to each user's requirements. The xenon lamp provides accurate readings and extends lamp life. The color touchscreen provides navigation, user login, access to pre-programmed methods, and test results. On-board memory stores up to 500 results, and an SD card slot provides or test result portability and system cloning that ensures common laboratory practices. The instrument also has USB, analog, and 36-pin parallel ports to provide connection to a computer or printer (sold separately).SpecificationsWavelength range190 to 1100nmSpectral bandwidth4nmAbsorbance range-0.300 to + 3.000AChamber capacity10 x 10mm cuvetteAbsorbance light sourceXenonResults storageUp to 500 on internal flash memory, or removable mediaComputer interfaceSD memory card slot, USB, 36-pin parallel, and analogDimensions220 x 490 x 390mm (H x W xD)Power requirements 100-230VAC, 50/60Hz, auto-detectingH is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to backA spectrophotometer is a device used to measure and analyze aspects of light absorption in liquids and solids.
