摘要

 

componentdescriptionwhy we recommend it
usb2000 xr1-esextended-range spectrometer (200-1025 nm) with enhanced sensitivity versatility. the extended range covers basic uv-vis measurements, in a configuration with good resolution and throughput.
dh-2000-balbalanced deuterium halogen light source (215-2500 nm)good uv response. absorbance peaks of the acai berry juice samples are largely in the uv region. the tungsten halogen part of the source allows measurements in the visible region.
 
cuv-uvcuvette holder, 1 cm pathlengthpracticality. unless we’re measuring cuvette samples in very high or very low concentrations, a 1 cm pathlength is ideal.
cv-q-10quartz cuvette, 1 cm pathlengthplastic uv cuvettes are convenient, but quartz cuvettes transmit more uv light.
qp450-0.25-xsr (2) solarization-resistant (sr) patch cords, 450 µm diameter, 25 cm lengthuv transmission efficiency. sr fibers prevent degradation that can result from uv light exposure and transmit uv very efficiently.
