Galaxy Scientific QUASIR 4000



The QuasIR™ 4000 was designed from the ground up to offer the industry a new kind of NIR analysis solution – a solution that brings together the portability required to move NIR analysis closer to point-of-need, combined with unmatched spectroscopic performance for the fastest and most accurate results. 
The QuasIR™ 4000 was engineered to ensure direct calibration transfer without the frustration of standardizing instruments or adjusting models to accommodate excessive instrument variability. The heart of the QuasIR™ 4000 is our PermAlign™ optics technology, an innovative optical design that maintains alignment and performance under conditions from the routine to the extreme. Our technology and design ensure unmatched consistency and direct methods transfer with no loss in performance so you can expand your QuasIR™ fleet with confidence. 
Experts know that good NIR results always start with good sampling and this means a large measurement spot size and the largest possible sampling volume. With this in mind, the QuasIR™ 4000 was engineered with an enhanced 23 mm sampling area, which is up to 5 times larger than competitive products. Our large sampling area with scratch resistant sapphire window helps produce better and more reproducible results. An internal background shutter mechanism permits automatic collection of background scans without the need for external reference materials or user interaction. An optional, easy-to-attach spinner further increases the sampling area, and various sampling cups and accessories increase the versatility of the instrument. 
Additionally, the QuasIR™ 4000 includes a transmission chamber that holds a cuvette or vial. Optional temperature control is available to enable a wide range of applications. Transmission samples such as edible oils, lubricants, and fuels can be easily analyzed for quality control or adulteration.
