APSS-2000 Liquid Particle Counter for USP 788

The APSS-2000 Liquid Particle Counter for USP 788 measures and counts suspended particle matter in a variety of liquids, particularly parenteral, to satisfy all current US, European and Japanese Pharmacopoeia requirements. It is critical to follow requirements while limiting waste when it relates to particle monitoring quality control for liquid medication producers.

The APSS-2000 Particle Counter features recipe functions to help it adjust to future policy measures, as well as USP 788 for particles in liquids, and its tiny sample capacity reduces the waste of valuable products.

The APSS-2000 Liquid Particle Counter, part of Particle Measuring Systems (PMS) comprehensive liquid particle counter series, contains an SLS-1000 Syringe Sampler, SamplerSight Pharma Software, and a LiQuilaz® eSeries Light Obscuration Spectrometer, which allows reports to fulfill 21 CFR 11 standards for electronic records and signatures.

SamplerSight Pharma Software enables operators to handle sample needs for batch-based procedures and gives a perfect overview of batch information, including a histogram, tabular data and time plot, all displayed in an easy-to-use manner that can be simply reported. SamplerSight Pharma has a Windows-based program that is validatable and user-friendly, with context-sensitive support.

The APSS-2000 Liquid Particle Counter for USP 788 is an entirely enclosed liquid particle counting instrument for syringe sampling.

From the several liquid sampling setups to the extensive Sampler Sight software, which allows the user to gather, examine and export data from a single platform, it gives the user flexibility. The software is 21CFR11 compatible and validatable. The below video tutorial reveals more.
