Tablet Hardness Tester TBH 425 Series (TBH 425 D, TBH 425 TD, TBH 425 WTD)
Brand: Erweka | Category: Scientific & Laboratory Equipment
The TBH 425 is a tablet hardness and combination tester for semi automatic measurement of up to 10 samples. Samples go into a star shaped feeder and are then transported automatically to the test station, where, depending on model, hardness and optionally thickness, diameter or length for oblongs can be measured on round or uneven samples. An alignment routine and an optional support groove in the hardness testing station help align irregularly shaped samples during breaking. The numeric keypad with alphanumeric sub function stores nominal hardness with three individual plus and minus tolerances, where T3 is the pass or fail criterion, plus comments for up to 50 products, and stored product data can be moved to other devices in the TBH 325 / 425 family by SD card or USB stick. Paired with the optional MC.NET software over the serial LAN or USB interface, the series is 100 % 21 CFR 11 compliant.

- Manual 5-Parameter Hardness Tester TBH II
The TBH II covers manual 5 parameter tablet hardness testing in one compact instrument, built for pharmaceutical quality control and research laboratories. It measures hardness up to 500 N, thickness, width for oblongs, diameter for round tablets or length for oblongs, and weight, giving pharmacopoeia compliant tablet testing across all five properties. A top mounted touch interface guides the operator through each test step with TestAssist, supported by robust mechanics and an ergonomic, space saving design. Four interchangeable magnetic inserts, flat and with 1, 2 or 3 mm groove radius, position and align tablets from 1 to 30 mm as standard, with an optional user changeable breaking jaw for larger tablets from 31 to 60 mm.
- Tablet Hardness Tester TBH 325 Series
The TBH 325 is Erweka's hardness or combination tester with an integrated product memory for up to 50 products, built robustly for smooth operation in production environments. Its numeric keypad with alphanumeric sub function stores nominal hardness together with three tolerances for each of up to 50 products, ready to be recalled for testing, and product names, remarks and batch or lot numbers can be entered before a test run begins. Recorded information and results can be printed on a connected printer or transferred to a computer through the LAN interface. Samples are inserted manually so all tablet types and shapes can be tested, and broken samples drop from the test station into an acrylic glass disposal container. Hardness is measured from 3 to 500 Newton in constant speed or constant force mode, with measuring sensitivity adjustable from 3 to 40 N.
- Tablet Hardness Tester EasyCheck
EasyCheck is a compact, fully automated entry level combination tester for routine tablet hardness work. It measures up to five parameters in a single workflow, weighing samples automatically through its integrated weighing cell so no manual handling is needed. The patented Oblong Slider aligns tablets precisely for consistent results across different tablet shapes, and a star shaped rotary magazine in stainless steel and aluminium provides 20 test positions while leaving the test process fully visible. An intuitive touchscreen stores up to 100 products, methods and users, and the instrument can be fitted with a test memory for up to 1 million test results, an audit trail light function for paperless reporting and CSV and XML data export.
