Used BECKMAN COULTER LS 230 #9186613 for sale

BECKMAN COULTER LS 230 is a bench-top particle counter designed for use in quality control, process control, and research applications. This particle counter can measure particle size (diameter) from 0.3 to 500µm, with accurate count data for particles larger than 4.0µm. It can measure up to 40,000 particles per second in a single liter of liquid, and is capable of counting particles up to 400 million per liter. BECKMAN COULTER LS230 uses a state-of-the-art ultra-impulse laser that emits a light beam into a test chamber filled with the test liquid. Light scattered by particles impinging the beam is detected by a photodetector. The scattered light is converted to an electrical pulse that's used to calculate the particle size. The operating temperature range is -10 to 40°C, and the instrument has a digital LCD display for ease of operation. LS 230 includes a USB port for connection to a PC and has a record storage capacity up to 1,000 records. LS230 has multiple operation modes, including Total, Specific Size, Differential, and Particle Size Distribution (PSD) modes. Total mode gives the total number of particles per liter, Specific Size mode allows the user to specify the size range for counting, Differential mode counts particles over two size ranges together, and PSD mode offers particle size distributions in 2-µm steps over the entire particle size range for a given sample. The instrument can be equipped with several accessories, such as an integral stand to help position the sensor at varying heights, an optional filter for high pressure or corrosive samples, and a low-volume kit for measuring small sample volumes. Additional accessories include filter holders, a rack desiccator, a cylindrical sample holder for filter paper, and a sampling stand. BECKMAN COULTER LS 230 is designed for easy setup and operation, and is lightweight and compact for portability. The instrument requires minimal set up and maintenance and delivers reliable and accurate count data. Additional features include built-in temperature and agitation controls, and an optical backscatter detector for background contamination measurement. This particle counter is an excellent choice for quality control and process control applications.
