Spatially Separated Laser Options (Beam Spot Size: 5 μm x 80 μm)
Fixed integrated optics and quartz flow cell design with >1.3 numerical aperture. Flow Cell dimensions: 420 μm x 180 μm internal diameter
Forward Scatter Detection
Proprietary Axial Light Loss (ALL) sensor system using silicon photodiodes with built in 488/8 μm band pass filter.
Fluorescence and Side Scatter Detection
Fluorescence and side scatter light delivered by fiber optics to Avalanche Photo Diode detector arrays. Proprietary design ensures high performance, high efficiency, low-noise signal detection. Emission profiles are collected using reflective optics and single transmission band pass filters.
Violet Side Scatter Configuration
Option to configure Avalanche Photo Diode detector array to collect side scatter signal from Violet (405 nm) laser. The configured channel (VSSC) can be utilized to better resolve nanoparticles below 200 nm size threshold.
CytExpert QC automation pass/fail criteria rCV < 5.0% for the all 13 fluorescent channels.

The CytExpert software is a full-feature software package that controls the instrument's operation, collection of experiment data, and analysis of the results.
Three different installation modes are available, depending on the level of security required. The Default installation requires no user login. For multiuser instruments, the User Management installation requires user login and contains features for role management. Electronic Records Management installation provides tools that facilitate compliance with 21 CFR Part 11, Electronic Records and Electronic Signatures.
An API (Application Programming Interface) is available and allows external software to perform operations such as running methods and for basic control of the plate loader.
Daily QC beads or any other reference material that is relevant for your application may be used as the standardization sample to set target values and calibrate the gain settings automatically. The Standardization Target Library stores a variety of application target files which are linked to the reference material lot numbers.
