XQ Automated Benchtop Powder Heads and Racks-Trays
Available for the XQ Instruments Automated Benchtop Powder Dosing Machines are additional small, medium, and large dispensing heads and dispensing head disks, along with other accessories. If there is a specific accessory you are in search of, please reach out to PSTG Supplies and we will be sure to add it to the catalog!
Heads and Disks
The dispensing heads are interchangeable to enable quick processing of several materials with different dose size and no cross-contamination without cleaning steps.
The dispensing disks (the dosing element) are calibrated for a specific dose size as per customer specifications. With the calibrated dispensing disk this dose or selectable multiples of it (up to 99x) can be dispensed. One shot takes 3.5 seconds.
Selecting multiple doses allows to dispense different dose sizes from the same dispensing disk-head, as long as they have a common denominator (resulting in an effect of resolution relative to target doses). However, with multiple doses dispensing time will increase and there can be a stack up error.
To change the single dose values, or switch to a material with different bulk density, the dispensing disk in the dispensing head needs to be swapped with one corresponding to the new value. This takes only a few seconds. Users might have a range of disks available for different materials and dose sizes. Additional disks to new specifications can be ordered from XQ Instruments at any time; e.g., when requirements change.
For switching instantly between materials and dose sizes it can be advantageous to have several heads at disposal in order to swap without the need of clearing out the material and no risk of cross-contamination. The dispensing heads in stand-by can be temporarily stored with material inside (ideally in a dry chamber). Such additional heads with calibrated disks are available as accessories.
The dispensing disks can be calibrated to any volume in the range of the individual head size. These volume ranges are as follows:

For small doses, the smaller dispensing heads are not more precise than the large ones. On the contrary, the large dispensing head can cope best with challenging materials in small doses. Therefore, it is the typical choice for the larger benchtop SDB-1. For the more compact form factor of the handheld SDH-1 the small and medium size head would be usually selected, even though the large head will also fit. The SDB-2 comes with its own XL head.
SDB-1R Custom Racks
These racks for the SDB-1R Automated Benchtop Power Dosing Machine are customized based on the container size. Can fit 50-150 tubes or vials depending on size.
