Angstrom Advanced UV1600/1800 series spectrophotometer

Introduction
The UV 1600/1800 series are developed for precise testing with a stray of light of only 0.05%T. The value is evident from the performance provided everyday. The local stand-alone software provides functions of Basic Mode, Quantitative Test and Kinetics and System Utilities.
Fundamental Principle
Data Store Function The Ram has the capability of saving 200 separate groups of data which can be recalled at any time and most importantly, if a sudden loss of power occurs. Users don't need to write down each test result in the notebook, thus saving time and increasing work efficiency. Standard Curve Build and Store Users can build their own standard curve on the screen and save it within the RAM. The curves can be reloaded at any time. Up to 100 curves can be stored. Coefficient Method If you know the coefficients of the curve equation, you can input the values and use them to test the samples directly. Kinetics Test The Kinetics curve can be displayed in the screen, you can use this function to test the samples and verify the instruments stability. System Function The instruments have the ability to calibrate the wavelength accuracy and dark current automatically by choosing the corresponding command in the Utility menu. Super PC Software (Optional) The software functions include 1) Kinetics 2) Quantitative Test 3) Wavelength Scan 4) Multi wavelength Test 5) DNA/Protein Test
Features
The Milas Deuterium is a world-leading lamp that has a long-lasting service life, high stability and high brightness. The Tungsten lamp also ensures a long service life and high stability on the UV spectrophotometer. The lamps feature pre-aligned design, so there is no need for professional adjustment while replacing a new one. Therefore users no longer need to hire professionals to change or adjust lamps which greatly improves reliability and cuts down on the maintenance expenses. The D2 lamp and the W lamp can be controlled individually to extend the lifetime. You can switch off the D2 lamp when in visible range or switch off the W lamp when in Ultraviolet range. Excellent optical performance Low Stray Light The Stray Light is only 0.05%T which enables the user to decrease the analysis Relative Error greatly. High Wavelength Accuracy Adopt advanced Guide Screw structure, which ensures the wavelength accuracy and repeatability. Outstanding UV and visible region are used with corresponding photometry accuracy of top-grade instruments (NBS930D standard, standard solution), which enables the instrument to be suitable for various quality control.

Angstrom Advanced Nitrogen Generating Plant by Membrane Separation

Introduction

The compressed air compressor filter into the polymer membrane filters, a variety of gas in the film in the solubility and proliferation of different factors, leading to different gases in the membrane penetration rate in a relatively different. According to the characteristics, various gases can be divided into "rapid gas" and "slow gas". After being compacted and purified (to remove oil, water and dust) the air will enter the membrane separation to separate. First, the O2, CO2 and some vapor will infiltrate into the membrane wall and then exit through the discharge port by air pressure; since the infiltrating speed of N2 is slower, it will flow out from the gas collector at the end of the pressure box and finally enter nitrogen buffer tank.

Specifications

N2 capacity	1-1000 Nm3/h
N2 purity %	>95-99.9%
Dew Point	≤-40C
Work pressure	0-2.0 MPa

Features
