Description
TW 7450 sample changer is a robust base unit intended for automated sample handling in titration laboratories and is supplied without titration head and sample rack. The unit includes a USB cable for direct connection to a PC together with a universal power supply rated 100-240 V, enabling straightforward installation in diverse laboratory environments. With a net weight of 66 kg the base provides a stable foundation for subsequent addition of titration heads and sample racks. This configuration supports efficient sequential processing of multiple samples, reducing manual handling and increasing analytical throughput. Manufactured by SI Analytics - a Xylem brand, the TW 7450 is engineered for integration into complete titration workstations used in industrial, pharmaceutical and environmental laboratories. Originating from the USA and delivered as a single piece, the base unit requires complementary components for full operation yet already offers reliable PC communication via its USB interface. It is well suited to high-volume routine analysis where automated sample presentation improves reproducibility and laboratory productivity.

What is this article?
TW 7450, Sample changer TW 7450, basic TW 7450 unit without titration head and is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand for laboratory use. It sits in Burettes, inside Volumetric glassware, in Labware.
A burette delivers a measured volume through a stopcock, which is how a titration is read. Class A and class AS state the tolerance. The stopcock, glass or PTFE, and the volume of the burette are the choices. A dirty bore changes the delivered volume.
Volumetric glassware is glass that has been calibrated to contain or to deliver one stated volume at a reference temperature. That calibration is the whole point. Class A and class AS have a tighter tolerance than class B. A volumetric flask contains. A pipette and a burette deliver. A measuring cylinder is the coarser reading, used when the volume is not the result. The classes sit under ISO laboratory glassware. The chain back to the unit of volume is the work of the BIPM and of NIST.
