μFocus targets give you a precisely formed dried droplet spot of predetermined size. You can work with larger (1700-2000 μm) spots and use standard spotting techniques. You can also work with much smaller spots (700-900 μm) that allow you to reduce the amount of matrix used, to maintain optimum matrix to analyte ratio with less concentrated or smaller analyte samples. Many users report 5-10x increases in sensitivity. Because μFocus spots are uniform, you also see improvements in spot-to-spot reproducibility, making quantitative analysis and fingerprint assays more reliable.

These sturdily constructed photometers use glass filters for colorimetric and turbidimetric analyses to obtain readings on a KlettTM scale. The measurements are in Klett units, and they are directly proportional to the solution's OD, according to Beer's Law. Other photometric instrument scales are 'shorter' than the Klett's and thus the Klett's readings offer greater exactness. Accessory filters provide measurement over the entire visual range and measurements for both color and turbidity are allowed. A pair of matched photovoltaic cells and a suspension galvanometer allow a wide range of readings; the unit is unaffected by light and ambient temperature. The galvanometer offers excellent exactness for its class, and features an illuminated logarithmic scale, with markings from 1 to 1000 KlettTM. Two models are available. The Industrial Model is compatible with rectangular cuvettes, which may be employed in one of two orientations. Readings are obtained at depths of 10mm, 20mm, or 40mm. An optional reduction plate may be used to reduce solution depth to . An optional adapter allows test tubes to be used in the Klett unit. The Clinical Model employs regular x 125mm test tubes. Can choose to purchase both calibrated or uncalibrated tubes. Micro test tubes may also be employed for small volume samples (as low as 2.5 ml). Both versions of the KlettTM include the blue (400-450nm) and green (520-580nm) glass filters. Comes with clear instructions, standards and usage guides for several common tests. Available in 115 or 220V. Durable construction for long service life• Reproducible results with exactness to % on the full scale• Measurements for both color and turbidity are possible• Balanced electrical circuits that are fully compensated avoid the use of storage batteries or current regulators Description: Calibration test kit Includes three test tubes-#0, 1, and 2; test filter, test tube adapter and instructions

Manufacturer: Thermo Scientific Brand: Thermo Scientific Orion Model: VSTAR-RD

This Thermo Scientific Orion VERSA STAR Dissolved Oxygen/RDO/Temperature module easily connects into VERSA STAR meters. The Dissolved Oxygen/RDO/Temperature module takes the worry out of DO probe compatibility - the meter accepts and automatically recognizes Orion polarographic and RDO optical/luminescence-based probes. It also compensates automatically for temperature, salinity with manual input and barometric pressure (automatic or manual) and allows for calibration using water-saturated air, air-saturated water, a Winkler titration or zero point. No need to turn off your meter to switch modules -meter automatically recognizes module changes. Temperature Mode Range: -5 degree to 105 degree (23 degree to 221 degree ). Temperature Mode Resolution: 0.1 (0.1). Temperature Mode Relative Accuracy: ±0.1. DO Mode Concentration Range: Polarographic-- 0 to 90mg/L; RDO optical-- 0 to 50mg/L0.01, 0.1.
