 Moisture Sorption Analyser - Vsorp

A moisture sorption analyser whose unique features match the requirements of a specific sorption application in research, development or in quality assurance is a guarantee for precise and reliable measurement results. Examples for such requirements are

  • Temperature range
  • Approriate balance resolution
  • Size, mass and number of samples to be analysed
  • Maintenance requirements and usability
  • Available budget

Moisture Sorption Analyser – Vsorp

With the combination of proven and reliable components and an advanced design, the Vsorp covers the requirements of a state-of-the-art multisample instrument: An easy to operate moisture sorption analyser for high sample throughput in research, development, quality assurance and material testing.

  • Optimized for best performance around room temperature
  • High accuracy and balance resolution from 100µg down to 1µg
  • Multisample instrument for 23 small, 11 medium or 5 large samples
  • Minimum maintenance requirements, easy operation
  • Attractive pricing

Optimized Temperature Range

The majority of measurements in typical application areas like food research or determination of sorption properties of chemical substances is done at and around room temperature. In many cases it is sufficient to determine the sorption isotherm at room temperature and some further temperatures close to room conditions. Very often, it is not required to measure at very high or low temperatures. The moisture sorption analyser Vsorp is therefore designed for best performance and stability in the temperature rangee from 15°C to 40°C.

Balance resolution

The requirements for the precision and resolution of the balance as well as the required balance load range are set by the size, mass and expected water uptake of the samples to be analysed. Small amounts of powder with low sorption capability require a high resolution and excellent repeatability for the acquisition of high value measurement data. For large, bulky and heavy samples, a balance with a high load range is required. For some applications a combination of an extended load range and high resolution is required.

The models of the Vsorp series are are available with a balance resolution of 1µg, 10µg or 100µg. The same proven and reliable top loading balance technology as for the Vapor Sorption Analyzer SPS is used that satisfies the high demands to reproducibility, stability and drift compensation.

Multi-sample capability

Sample carousels are selected according to the sample size and number of samples. Changing from one carousel to another between two measurements is done within seconds. With the available carousels, all kind of sample sizes from a few milligram of fine powder up to large and heavy samples like product packages and even concrete can be handled.

Reduced side costs

Combining our longstanding experience in the construction of measurement devices with state-of-the-art manufacturing, the Vsorp stands for for high reliability, minimized maintenance and low operating cost. Large and plain inner surfaces facilitate cleaning of the instrument. Except for refilling and cleaning of the water supply tank from time to time, the Vsorp is almost maintenance free.

Calibration of the balance is done by an automated internal calibration routine. For humidity validation, ProUmid offers a certified reference material that enables the execution of a validation routine in parallel to a running measurement.

High Versatility

In order to cover a multitude of applications and to provide an instrument that fits the users needs best, the moisture sorption analyser Vsorp is available in three different models: Vsorp Basic, Vsorp Plus and Vsorp Enhanced. Each model covers a different range of applications concerning balance resolution, sample size and number of samples. Please see the Technical Specifications to select the Vsorp model that fits best to your application.

    Step 1: Select temperature range

    Step 2: Select additional sensors

    Step 3: Select additional measurement methods

    Step 4: Select instrument by sample size, sample sorption capacity or the type of application.

    If you can tell us about the samples you want to analyze, the available sample quantity, the sample hygroscopicity or your area of application, we can give you a recommendation for the device that meets your requirements best.

    Step 5: What is the average sample quantity available and/or how hygroscopic are the samples?

    Tiny: <10mg, very low hygroscopicity
    Small: >10mg, low hygroscopity
    Medium: >100mg, moderate hygroscopicity
    Large: >500mg, abundant hygroscopicity

    Step 5: Which field of application is most likely to apply to your samples?

    A: Pharmaceutical pre-formulation
    B: Pharma, Food, Fine Chemicals, Cosmetics, Material characterization, Polymers, Electronics, Fibres, Paper, Wood Analytics, Textiles
    C: Building Materials (concrete, wood, insulation), Fertilizer, Permeability and Packaging testing

    Recommended Instrument(s):

    Additonal sample trays such as the Permeability kit and the requirement for tiny samples do not match. Try to deselect the additonal sample tray or to increase the sample size.

    Additonal sample trays such as the Permeability kit and the application pharmaceutical pre-formulation do not match. Try dp deselect the additonal sample tray or to select a different field of application.
