Equipped with a xenon flash lamp, it offers fixed wavelengths at 230, 260, 280, 320, 562, and 595 nm and features a holographic concave grating for precise spectral dispersion. Its program-controlled wavelength selection and low spectral bandwidth—5 nm for lower wavelengths and 7 nm for higher wavelengths—combine with minimal systematic and random errors to deliver exceptional measurement accuracy, with a reading precision of 0.001 A and stray-light levels below 0.05%. Enhanced by 12 preprogrammed, modifiable method programs and high-quality silicium photodiodes for sensitive detection, this bio-photometer provides outstanding reliability and repeatability. All of these features are housed in a robust metal casing that ensures long-term operating stability, making it an indispensable tool for any laboratory.\n\t\t\u003cbr\u003e\u003cbr\u003e\n\t\tThe Eppendorf BioPhotometer Model #6131 is fully tested to perform at factory specifications before being shipped.\n\t\t\u003cbr\u003e\u003cbr\u003e\n\t\u003c\/p\u003e\n\t\u003cdiv class=\"included-box\"\u003e\n\t\t\u003cspan class=\"included-header\"\u003eINCLUDED:\u003c\/span\u003e\u003cbr\u003eThe Eppendorf BioPhotometer Model #6131 includes:\n\t\t\u003cul\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003eCalibration Certificate\u003c\/li\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003ePower Cord\u003c\/li\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003eOperator's Manual\u003c\/li\u003e\n\t\t\t\u003cli\u003e\n\u003cspan class=\"hidden-car\"\u003e\u0026gt; \u003c\/span\u003eFull 180 Day Parts and Labor Warranty\u003c\/li\u003e\n\t\t\u003c\/ul\u003e\n\t\u003c\/div\u003e\n\t\u003ch2\u003eEppendorf BioPhotometer Model #6131 Specifications\u003c\/h2\u003e\n\t\u003ctable\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWavelength Range (Fixed)\u003c\/td\u003e\n      \u003ctd\u003eXe 230, 260, 280, 320, 562, 595 nm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpectral Bandwidth\u003c\/td\u003e\n      \u003ctd\u003e\n        \u003cp\u003e5 nm at 230 to 320 nm\u003c\/p\u003e\n        \u003cp\u003e7 nm at 562 to 595 nm\u003c\/p\u003e\n      \u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWavelength Selection\u003c\/td\u003e\n      \u003ctd\u003eMethod-dependent, program controlled\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWavelength Systematic Error\u003c\/td\u003e\n      \u003ctd\u003e\n        \u003cp\u003e± 1 nm at 230 to 280 nm\u003c\/p\u003e\n        \u003cp\u003e± 2 nm at 320 to 595\u003c\/p\u003e\n      \u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWavelength Random Error\u003c\/td\u003e\n      \u003ctd\u003e\n        \u003cp\u003e≤ 0.002 A at 0 A\u003c\/p\u003e\n        \u003cp\u003e≤ 0.005 A at 1 A\u003c\/p\u003e\n      \u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePhotometric Random Error\u003c\/td\u003e\n      \u003ctd\u003e\n        \u003cp\u003e≤ 0.002 A at 0 A\u003c\/p\u003e\n        \u003cp\u003e≤ 0.005 A at 1 A\u003c\/p\u003e\n      \u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePhotometric Systematic Error\u003c\/td\u003e\n      \u003ctd\u003e± 1% at 1 A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOptical System\u003c\/td\u003e\n      \u003ctd\u003eAbsorption single-beam photometer with reference beam and several fixed wavelengths\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eIrradiation Source\u003c\/td\u003e\n      \u003ctd\u003eXenon flash lamp\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSpectral Dispersion\u003c\/td\u003e\n      \u003ctd\u003eHolographic concave grating\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eAccuracy of Reading\u003c\/td\u003e\n      \u003ctd\u003e0.001 A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eStray-Light Proportion\u003c\/td\u003e\n      \u003ctd\u003e\u0026lt; 0.05%\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRadiation Detector\u003c\/td\u003e\n      \u003ctd\u003eSilicium Photo Diodes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMemory\u003c\/td\u003e\n      \u003ctd\u003e12 preprogrammed, modifiable method programs\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eDimensions (W x H x D)\u003c\/td\u003e\n      \u003ctd\u003e7.9 x 12.6 x 3.9 in.
