This is the 2 Liter capacity build tray (tank, vat), for the new Asiga Pro4K 3D Printer.
All the Pro4K trays have the same dimensions and are made of the same materials. The difference in the trays is the read/write RIFD tags on each tray that determines the volume of material that can be built with the particular tray. People that use small volumes over a longer period will find a value in these lower cost trays. If you are building large volume parts or a high quantity of parts per build, you may want to consider a tray with a higher capacity to take advantage of the more efficient value of the higher volume use trays.
