Model Guides
TFT-1 — Dual-drum with variable speed (20–100 rpm) and programmable run count (5–900 turns). Recommended for labs running simultaneous dual-batch QC or requiring non-standard speed protocols.
TFT-2 — Compact single-drum at fixed 25 rpm for 100 turns. The standard pharmacopeial protocol in a space-efficient footprint.
TFT-3 — Dual-drum with variable speed and 50 W drive for demanding method-development or continuous high-throughput workloads.
TFT-4 — Single-drum at fixed 25 rpm with programmable turn count (10–900 turns), combining protocol flexibility with a compact, lower-power design.
How It Works
The friability tester operates on the principle of controlled mechanical attrition through repeated impact and abrasion cycles. Tablets are loaded into transparent acrylic drums that rotate synchronously at 30 rpm, causing specimens to tumble and fall repeatedly from a standardized height of 156 mm. This controlled mechanical stress simulates the handling, packaging, and transport conditions that tablets encounter during manufacturing and distribution.
The dual-drum configuration enables simultaneous testing of multiple batches or formulations under identical conditions. Each complete rotation subjects tablets to impact forces and surface abrasion that reveal structural weaknesses, coating defects, or inadequate binding. The automatic cycle counting system ensures precisely 100 rotations per test, providing standardized exposure conditions for reproducible friability measurements.
Weight loss is calculated by comparing pre-test and post-test tablet masses, with friability expressed as a percentage. The transparent drum construction allows real-time observation of tablet behavior, enabling detection of capping, lamination, or other mechanical failures that may not be captured by weight loss alone.

Practical Tips
Verify rotation speed annually using a certified tachometer to ensure 30 rpm ±1 rpm accuracy for pharmacopeial compliance.
Why: Speed drift can affect stress delivery and compromise result reproducibility across test sessions.
Clean acrylic drums with mild detergent and soft cloth after each use, avoiding abrasive cleaners that could scratch the transparent surface.
Why: Surface scratches can impede visual observation and create stress concentration points affecting tablet behavior.
Record initial tablet weights to 0.1 mg accuracy and handle specimens with powder-free gloves to prevent contamination.
Why: Precise weight measurement is essential for accurate friability percentage calculation and regulatory documentation.
Condition tablets to laboratory temperature and humidity before testing to ensure consistent mechanical properties.
Why: Environmental conditions affect tablet moisture content and mechanical strength, influencing friability results.
Document any visible tablet defects or abnormal breakage patterns observed during the test cycle in addition to weight loss data.
Why: Visual observations provide qualitative context that enhances quantitative friability measurements for formulation assessment.
If drums show uneven rotation or vibration, check mounting alignment and ensure the instrument is properly leveled.
Why: Mechanical imbalance can create non-uniform stress distribution affecting test validity and result reproducibility.
Ensure drum covers are properly secured before initiating test cycles to prevent tablet ejection during rotation.
Why: Proper containment maintains safety and prevents sample loss that could compromise test results and laboratory safety.
