• Product Detials:Display Mode: 4 digital LED Lamp: Halogen-Tungsten Lamp Optical system: C-T configuration diffraction grating monochromator Interface: RS232 serial port Dimensions: 370/320/210 mm Weight: 6.5Kg Features 1. Whole aluminum metal alloy die-castings. 2. Pre-aligned halogen-tungsten lamp, offer ease of use and simple maintenance. 3. Built in SCM technology, auto 0%, auto 100%, error-free T/A transformation. 4. Transmittance test, absorbance test, concentration factor setting and concentration direct readout functions. 5. Using universal? 12+0.4× 100 mm testing tubes or cuvette to make measure directly. 6. Analysis with data processing software. Specificatios Wavelength Range: (340-950)nm Wavelength Accuracy: ± 2.5nm Wavelength Reproducibility: ≤ 1nm Spectral bandwidth: 12 nm Photometric Accuracy: ? 2%(τ ) (tube),? 0.5%(τ ) (cuvette) Photometric Reproducibility: 0.3%(τ ) Stray Light: ? 0.5%(τ ) Photometric range: TRANS: 0-199.9% ABS: -0.3-2.999 FACT: 1-9999 CONC: 0-9999 Standard Configuration 1) WS-10S23A spectrophotometer 1 set 2) 1cm glass cuvette 1 pair 3) cuvette rack 1 PC 4) Power cable 1 PC 5) User manual 1 PC 6) Certificate of quality checking 1 PC 7) Fuse (2A) 1PC 8) Packing list 1PC Optional Accessories 1) Fuse (2A/3A) 2) Pre-aligned halogen-tungsten lamp 3) Glass cuvette 1 cm 4) Praseodymium-Neodymium optical filter 5) Mini printer 6) Printer cable 7) Spectrophotometer data processing software package 8) Comunication cable How to select the test tube Generally the round test tube is not for optic purpose unless it is pre-checked strictly. 1. Check size. (The size should be? 12+0.4× 80 mm) 2. Check the surface of tube. (It should be no bubbles, no scabs, no thread like things. ) 3. Warming instrument and set the wavelength at 360 nm. 4. Pour some pure water into tube and insert it to the test tube well in sample apartment. Then put some mark on the tube opposite the white mark at the instrument. 5. Put the other test tube into instrument one by one and get the readout for everyone and put mark at everyone. We can divide them in many groups. In each group the differential of readout for every tub is less then? 0.02A. 6. We can use tubes in same group for blank, sample, and standard solution needn't check the tube every time.
