The VST baskets deliver consistent extraction performance over a wide range of concentrations with reduced sediment. It is designed to extract properly and expertly amongst most bottomless portafilters, including Rancilio, La Cimbali, La Marzocco, and Nuova Simonelli, Quick Mill, Izzo, Rocket, Giotto, Isomac, Vibieme, and more. Each insert basket is uniquely coded for manufacturing QC and product authenticity.
The VST baskets were specially created with holes that were fabricated using a new micro-machine and finishing process. Each and every hole on every single basket was measured for the minimum and maximum range limits on area and diameter to a precision of +/- 30 µm. They were also calculated for circularity, placement, square area, and any blocked holes before being considered fit for sale and fitted for Baristas. The hole pattern is centered to +/- 1.0 mm and placement is oriented for uniform extraction throughout the entire puck.
The VST Insert Basket was specifically designed to stand the test of time. The wide outlet angle prevents the filters from clogging and the anti-wear design ensures uniform performance for the life of the product. The structural integrity has been improved, able to withstand deflection from pump cycling without any premature fatigue failures.
