Sample Trays
The proUmid DVS instruments are compatible with various exchangeable sample trays, using different sample dishes in number and size.
Sample Tray with 23 Sample Positions
Sample tray for 23 samples. Samples dishes suitable for small amounts of powder, granulated material or solid samples such as tablets, capsules as well as small pieces of electronics, plastics or plaster.
In addition, there are 23 further sample positions on an inner ring. These secondary samples are exposed to the same temperature and humidity conditions. However they are not weighed during the measurement. Secondary samples can be removed during a measurement and subjected to external analysis in their current state (moisture content, water activity), such as X-ray powder diffraction (XRD). This is particularly useful in pharmaceutical applications. For example, when a phase transition to a hydrate is observed in one of the primary samples during the measurement.
Diameter of the sample dishes: 33 mm (secondary sample dishes 18 mm)
DVS instrument compatibility: SPSx-1µ-Advance, SPSx-1µ-High-Load, SPS11-10µ, Vsorp Plus and Vsorp Enhanced
Sample Tray with 11 Sample Positions
The sample dishes with their large, flat bottom area are suited for all different kinds of samples. For optimal sorption conditions, small amounts of powder can be applied in a very thin layer on the large bottom area. Larger sample quantities of coarse-grained granules, inhomogeneous bulky or lumpy samples can also be examined.
A second, inner circle of samples allows for 11 additional samples. These parallel samples can be extracted from the device for further analysis during a running measurement or are available for further examination after the end of a measurement.
Diameter of the sample dishes: 50 mm (secondary sample dishes 38 mm)
DVS instrument compatibility: SPSx-1µ-Advance, SPSx-1µ-High-Load, SPS11-10µ and all Vsorp models
Sample Tray with 5 Sample Positions
Sample tray for 5 large, voluminous samples such as powder with a very low bulk density (e.g. fumed silica) or inhomogeneous bulky samples which require a large amount of material for a representative sample size, lumpy samples such as plaster, plastic or electronic parts, fiber materials or solid foams such as insulating materials.
Diameter of the sample dishes: 86 mm
DVS instrument compatibility: Vsorp Basic and Vsorp Plus
SPS23-100n Sample Tray
Sample tray for the SPS23-100n instrument. The sample dishes are specially designed for holding smallest sample quantities and adapted to the requirements for weighing with a submicro scale.
Additional 23 parallel sample positions are available on an inner circle. These secondary samples are not weighed and can be extracted during a measurement for further analysis, for example in an X-ray diffractometer, if required.
Diameter of the sample dishes: 18 mm
DVS instrument compatibility: SPS23-100n
