Options

 

UV Solutions program
(P/N 2J1-0310)

The UV Solutions program enables a PC to control the U-1900.When this program is installed, the following programs are usable.
(A Windows®XP compatible PC needs to be prepared separately.)

Option package program
(P/N 2J1-0311)

Capable of performing color calculation and color difference calculation.

Nucleic acid measurement program
(P/N 2J1-0316)

Usable for checking extraction and refinement of nucleic acids such as DNA/RNA essential for genetic research. Data (photometric values at 230, 260 and 280nm), and calculation results (260/280, nucleic acid concentration, protein concentration, molar concentration) can be displayed collectively on the screen.

GLP/GMP program
(P/N 2J1-0317)

The burden of optical instrument performance check can be alleviated.
Item-dependent measurement mode and automatic measurement mode (when no sample is necessary) have also been prepared.
In addition, a judgment tolerance range is settable so as to meet each analytical purpose.

Report generator program
(P/N 2J1-0312)

Developed to enable freely customizing the report output format of measurement results. Each character size and position of report items and comment are settable and besides, mathematical calculations conventionally dependent on manual method can be executed by spreadsheet program functions.

UV Navigation program
(P/N 2J1-0313)

Provides support for automation of measurement, data processing and printout.
Measuring procedure can be readily programmed using a graphical editor for implementation
of spectrophotometer control, measurement result indication and judgment, etc. Because analytical procedure can be automated, it is possible to save labor and form working patterns. This is effective for routine work such as quality control.



U2900-2910


Spectrophotometer simpler to use an higher in dependability thanks to mounting of a large-size color LCD.

High resolution satisfying European Pharmacopoeia (spectral bandpass: 1.5nm).
Trace-amount measurement in biotechnological field, etc. can be carried out using optional 50, 25 and 5micro cells.
