We are glad to introduce our XRD system - the DRON-7 General-Purpose X-ray Automated Diffractometer - the only one multifunctional diffractometer manufactured in Russia. The instrument was introduced to the market in Russia and C.I.S. in year 2004.
Special Features
Widely known immobile diffractometers of the DRON series, produced by our enterprise since 1960s, are proven as highly reliable analytical instruments that have never failed for several decades. It is till today that several thousands of the instruments manufactured in 1970s and 1980s are used in numerous science and research, industrial laboratories.
The new DRON-7 instrument, keeping those traditions, stands out among its predecessors with its
The DRON-7 Diffractometer includes: a goniometer on integrated servodrives, a high voltage power supply unit, a detector, an X-ray tube, a control and data collection unit, protection against X-ray radiation, and software.
A high-frequency air-cooled power supply unit provides the instrument's stable operation for a long period of time, that enabling reliable control of your products' quality and obtain valid results of your process developments and science research.
The goniometer's modular design and that of its electronic controls enables the instrument's easy upgrading and makes its service and maintenance to be simple.
Flexible design of the diffractometer and well devised control software promotes its easy adaptation to various conditions and tasks of your research and industrial laboratories, as well its integrating in process lines to control the features you need for middle and end products of your production facilities.
Operation of the diffractometer, data collection and measurement results' processing are controlled by a PC, with a Pentium processor, RAM 64 MB minimum, HDD 2 GB minimum, color monitor 15" minimum, serial interface RD232 and license version for OS Windows 2000/XP/Vista.
Software for control and data collection provides:
Application
The X-ray diffractometer is designated for solving a wide range of analytical, technological and research of materials science tasks. It is irreplaceable in X-ray diffraction research for any polycrystalline material. Independent rotation around axes 2θ and θ also enables the use of the instrument to solve several single crystalline diffractometry tasks.
If your interests involve:
the DRON-7 X-Ray Diffractometer will assist you in solving your production, process, research and environmental problems.
