Description

By displacingDryFlo, a dry, free-flowing powder with 'fluid-like' flow behavior, the GeoPyc automatically calculates the volume and density of a solid object. The medium comprises a small number of stiff, tightly packed, small spheres with a high degree of flow ability that are closely packed around the item being studied. Because the particles are tiny enough, they tightly adhere to the object’s surface during consolidation without invading the pore space.

Features and Benefits

Delivers data from a controlled-compression analysis in as little as 15 minutes

Can be applied to powders to produce compressed bulk density or formed pieces to offer envelope density

Since the items under analysis are devoid of waste and dangerous materials, cleaning and disposal will be simple

Operation made simpler with completely automated instrument control

Able to function independently and deliver results via email or a web browser

The capacity to save, program, and utilize many analysis method files

Operationally simple due to user-replaceable piston tip

Extremely cheap running expenses because no hazardous materials are required

Information accessible in CSV download format or as printed reports

Technology

The attainment of repeatability and reproducibility is possible through regulated compaction techniques. The dry medium is placed inside a precision cylinder sample cell. As the cell vibrates, a plunger compresses the powder; the force of compression may be chosen, making test after test repeatable. Preliminary compaction using the displacement media alone in the cell establishes a zero-volume baseline.

The compaction procedure is then performed with the sample in the cylinder containing the dry medium.The displacement volume of the medium is calculated by measuring the variation between the piston's penetration depth into the cylinder during the test (ht) and its penetration depth during the baseline procedure (h0).This difference in depth, represented as h=h0−ht, is then used in the formula for the volume of a cylinder with height h, given as V=πr²h, where V is the volume and r is the radius of the cylinder.

A sophisticated touchscreen controls the GeoPyc. The complete automation of data reporting and collecting makes integrating with LIMS and other data-concentrating systems easy. Numerous sample chamber options suit a broad range of sample sizes. Following the analysis, a quick shake or dusting eliminates the Dry Flo entirely, allowing the samples to be reused or retested.

The GeoPyc offers many working modes to suit the requirements, such as full blank, computed blank, and reference solid calibration with variation. It is feasible to follow developments during analysis, thanks to progress indicators and initial findings.

Configuration

T.A.P. Density Option

The GeoPyc T.A.P. density option is faster, quieter, and more reproducible than traditional tap density analyzers while still producing accurate readings that are comparable.

The GeoPyc evaluates the packing volume and determines the bulk density of granular and powdered samples, including pharmaceutical and electrochemical materials, under various compaction circumstances when outfitted with the T.A.P. Density option.

The sample chamber is turned and shaken while a precise, predetermined force is given to the sample to calculate the T.A.P. density. The consolidation force is measured in Newtons by a force transducer, and the consolidation piston and plunger travel distance are measured in steps. The user sets the number of consolidations per analysis and the force used. The GeoPyc automatically determines volume and density by averaging the values from each consolidation and reporting the findings in cm³ and g/cm³.

The GeoPyc’s clever touch screen allows users to access its various operating modes. Operating modes allow users to maximize accuracy and speed for a given application include full blank, computed blank, and reference solid calibration with variation.

It is feasible to follow developments during analysis, thanks to progress indicators and initial findings. Information particular to a sample can be included in the analysis reports. The following reports are available: Force Calibration, Instrument Log, Envelope Density, Blank Report, and Volume Calibration.
