UL-4000

UL-4000 is key analytical instrument, the spectrophotometer enables quantitative and qualitative analysis through spectrophotometry. It is widely applied in scientific research and industrial testing, including studies of nucleic acids, proteins, and bacterial concentrations

Product Description

Microscale sample test,and only 0.5 to 2 ul is required to complete the test,minimum 0.5ul ,ultromicro and cuvette areoseibla

Wildly test area, 100 times of the traditional spectrophotometer

No need to dilute for most samples

Test directly, no need to warm-up, container test and daily consumtion test

Whole wavelength 190-1100nm, accuracy 1nm, auto scannig wavelength 190-850nm

Compact size and partable package fitable for on-site test

2 in 1 function, support OD600 detection function, in order to detect the growth density of cells, bacterial liquid, yeast, comprehensive function, multi-purpose

Built-in thermal printer, with printing function, can store about 100,000 copies of detection data, can be exported through the USB interface, goodbye to data loss

Intelligent measurement without pressing any key directly out of the detection line

Packaging & Shipping

After carefully unpacking the contents, check the materials with the packing list (page 4) to ensure that you have received everything in good condition.

Place the instrument in a suitable location away from direct sunlight. In order to have the best performance from your instrument, keep it as far as possible from any strong magnetic or electrical fields or any electrical device that may generate high-frequency fields. Set the unit up in an area that is free of dust, corrosive gases and strong vibrations.

Remove any obstructions or materials that could hinder the flow of air under and around the instrument.

Use the appropriate power cord and plug into a grounded outlet.

Turn on your spectrophotometer. Allow it to warm up for 15 minutes before taking any readings. We suggest you then do the Calibrate System with the Search 656.1nm to set the wavelength to the deuterium lamp emission line.
