LIQUID PARTICLE COUNTER LS-20 ACCORDING TO USP 788

The Lighthouse LS-20 liquid particle counter has an integrated syringe sampler and optical particle counting system. The easy-to-use Windows-based software is designed to meet EP and JP international regulations and USP 788 requirements. The LS-20 liquid particle counter has been designed to a quality standard of reliability and dependability, using the latest laser optical particle counter technology.

The LS-20 uses a high precision syringe pump flow control system and high sample volume sensor. With an adjustable sample volume of 1 to 1000 milliliters (10 ml syringe), the liquid particle counter is a perfect instrument for multi-batch sampling. A magnetic stirrer continuously prevents sedimentation of the sample in the test vessel.

Thanks to the graphical user interface, the LS-20 is easy to configure and operate. Data is automatically recorded from up to eight particle size channels ranging from 1.0 to 50.0 or 1.0 to 200 microns and is available in real-time in graphical and tabular form. All reports can be pre-configured and printed at the touch of a button.
