spectrophotometer 4251/50 [H] OPTICAL EQUIPMENTS High end spectrophotometer especially suitable for Molecular Biology features it presents only 0.05 % stray light and a band width of 2 nm or Biochemistry laboratories since it allows qualitative (absorbance and which assure accurate and precise readings. transmittance measurements), quantitative (concentration measurements) and kinetics analysis in the UV-visible range. With excellent — Features 1| Large easy-to-read LCD display (128x64 bits) that shows the different results as well as the concentration curves and their equations and the kinetics curves in real time. 2| Memory to save up to 200 groups of data. The memory can also store and reload up to 200 different standard curves being ideal in assays with samples of the same nature and speeding up daily lab work. 3| Precise wavelength setting by using the keyboard with a resolution of 0.1 nm. 4| Data can be restored after a sudden power cut. 5| Tungsten and deuterium lamps (model 4211/50) can be turned on/off independently to extend their lifetime 6| Sample compartment with external manual exchanger that can hold up to 4 cells of 10 mm path length. 7| Application software that provides a complete control of the spectrophotometer functions from a computer and allows performing scanning, multi-wavelength and DNA/protein analysis. — Functions - 1| Basic mode: absorbance and transmittance measurements at a certain wavelength. 2| Quantitative mode: determination of the concentration of different samples from a curve equation (C=k-A+b). Two methods: a | Coeficiente: el valor de los coeficientes k y b de la ecuacion se introducen directamente a traves del teclado. b| Curva estandar: permite utilizar hasta 9 muestras patron para establecer la ecuacion de la curva estandar. 3| Modo cinetica: para analisis a lo largo del tiempo y calculo de velo-cidad de reacciones enzimaticas con posibilidad de programar el tiempo total del analisis y el intervalo de tiempo entre una medicion y la si-guiente. — Technical specifications Code Model Wavelength range Band width Optical system Wavelength accuracy Wavelength repeatability Wavelength resolution Photometric range Photometric accuracy Photometric repeatability Stray light Stability Lamps Detector Sample compartment Outputs Power Dimensions HJD003 4251/50 190-1100 nm 2 nm Single beam, gratting 1200 lines/mm ± 0.5nm 0.3 nm ± 0.1 nm -0.3/3 A, 0-200 %T ± 0.3 %T ± 0.2 %T 0.05 %T at 220 nm, 340 nm ± 0.002 A/h a 500 nm Tungsten and deuterium Silicon photodiode 4 standard cells of 10 mm path length USB port and parallel port (printer) AC 220V/50Hz or AC 110V/50HZ 470x370x180 mm Note: manufacturer reserves the right to modify features and photographies of the goods
