Fully Automated 4-in-1 Tablet Testing Instrument

Fully Automated 4-in-1 Tablet Testing Instrument, WHT 4 from Pharma Test

06-08-2020

Test diameter/length, weight, thickness/height, and hardness of normal, unusual shaped tablets (caplets, oblongs, etc.) fully automatically as well as solid samples. The WHT 4 from PHARMA TEST is used for the fully automated testing of single tablet critical parameters including weight, thickness, diameter and the tablet hardness (in compliance to the European and German Pharmacopoeia for uniformity of mass)

Offering a reliable and reproducible self-contained feeder and measurement station for quality control of samples throughout tablet production and in post-production QA and QC laboratories. The WHT 4 testing instrument do four test parameters of one sample. WHT 4 is a separate unit with an integrated touch screen PC running the WHT32 software. A single/ multiple-batch feeder can be used to separately file the samples into the testing system for entirely automated control of several samples and batches. Using the single feeder WHT 4-SM1 as well as direct connection to a current tableting machine can be done. The multiple batch feeder WHT 4-SM is employed to test up to ten different products unattended and fully automatically.
