The thousand grain weight TGW (also called 1000 grain mass) is an important quality criterion in seed tests, which must be determined with great accuracy. The TGW or the derived value “number of parts per gram” are also an important parameters in the production and quality control of technical and pharmaceutical granules. Using an additional software module, an electronic balance and a special base frame, the elmor C3 precision counter can be used to directly determine the TGW of a sample. Both the C3 and the scale are connected to the control computer. A freely selectable quantity is counted and falls on the weighing pan. At the end of the counting process, the weight of the sample and the corresponding number of particles are automatically transferred to the PC, where the TGW is calculated. This is all done without manual input, so errors are avoided. The equipment allows tests to be carried out in accordance with ISO 520.
In its new version, the completely redesigned PC-controlled elmor C3 precision counter presents itself not only with a different visual impression but also with completely renewed “inner values”.
The extremely wide range of parts that can be counted with the C3 has been expanded in the micro range. The smallest still countable parts are at some 10 microns. The application limit is no longer determined by the sensors and evaluation electronics, but only by the product properties. The smallest parts, which can still be conveyed and singularized, are counted with the C3.
Most obvious, however, is the new control software. It is optimized for Windows 10 and allows convenient entry of all setting values as well as the storage and transfer of the relevant data for further evaluation or archiving, so that the traceability of the counting operations is guaranteed.
For the requirements of the users in the pharmaceutical and food sector, steel 1.4404 (AISI 316L) was chosen for the product-contacting materials. The bowl can be offered with FDA conformal coatings. An internal self-test was added as a new feature. It allows the new C3 counter to be integrated into GMP-compliant procedures, allowing it to perform a functional or operational qualification.
The new top model of the elmor counters comes in the following steps on the market.
From December 2018, the renewed C3 will be available with the modules “Totalizator” and “Preset Counter”. From January 2019, the module “Thousand Grain Weight” will also be delivered. For exact, largely automated and manipulation-proof determination of the thousand-kernel weight, a complete set is offered consisting of the C3 counter, a laboratory balance and all necessary accessories.
In spring 2019, the “Particle Size Measurement” module will be available in a new form. For the second half of 2019 a GMP suitable version of the control software is planned. With this version, setting data for critical products can be predefined and saved via an administrator function. The user can then work with these predefined settings, but has no authorization to change them.
