Introduction to Tablet Hardness Tester
The Tablet Hardness Tester is a specialized instrument designed to measure the mechanical strength of pharmaceutical tablets. It evaluates how much force a tablet can withstand before it breaks, helping manufacturers ensure that each dose maintains its shape and performance from production to patient delivery.
In pharmaceutical manufacturing, improper tablet hardness can lead to issues like crumbling during packaging or overly hard tablets that don’t disintegrate properly in the body—both of which affect drug efficacy and safety. This is why tablet hardness testing is a critical step in pharmaceutical quality control.

Test Method Overview
How does it work?
During the test, the tablet is positioned between two platens. The upper platen applies a controlled force vertically until the tablet fractures. The breaking force (in Newtons) is recorded to assess tablet hardness.
Standard Reference:
The test procedure aligns with USP – Tablet Breaking Force, which provides guidelines on: Loading rate (≤ 3.5 mm/s or ≤ 20 N/s) Sample orientation Calibration requirements Valid sample size (minimum 6 tablets)

Frequently Asked Questions (FAQ)
📩 Contact us today to learn more or request a quote tailored to your testing needs.
Q1: How many tablets are required per test?
A: According to USP <1217>, at least 6 tablets should be tested to ensure accurate and statistically meaningful results.
Q2: Can I test scored or coated tablets?
A: Yes. The tester supports multiple fixtures and orientation methods, suitable for scored, coated, chewable, and irregular tablets.
Q3: What’s the difference between hardness and friability?
A: Hardness measures a tablet’s resistance to breaking under pressure, while friability tests how well a tablet resists surface abrasion.
Q4: Is calibration required regularly?
A: Yes. For compliant testing, periodic calibration is required using certified reference weights or load cells.
Q5: Can your system connect to LIMS or export data?
A: Yes. Our testers offer RS232 output, optional software, and support for integration with data management systems.
