Computerized Melt Flow Index Tester (Test Method A)

About Computerized Melt flow index tester (Test Method A)

As per ASTM D 1238 & ISO 1133 - (Test Method A) to check the melt flow rate (MFR) of thermoplastics and compounds with auto cutting of flowing extrudate and prelogic facility.

The Computerized Melt Flow Index Tester (Test Method A) is a fully automatic, PC-interfaced MFI tester that takes melt flow testing to the next level. Built to ASTM D 1238 and ISO 1133 Test Method A, it determines the melt flow rate (MFR) of thermoplastics and compounds with automatic cutting, automatic weighing of the extrudate and software-driven result calculation.

An integrated weighing scale (resolution 1 mg, capacity 60 g) sits directly beneath the cutter, so once the operator loads the polymer in the barrel and presses Start, the entire test runs hands-free. The PC software stores individual MFI results, calculates the average, and exports data for QC documentation. The instrument is ideal for laboratories that need high testing throughput with minimum operator dependence.

Frequently Asked Questions

What is the advantage of the built-in weighing scale?

The integrated balance weighs each cut sample directly with 1 mg resolution. This removes the need for a separate weighing balance, eliminates the risk of sample loss during transfer, and lets the software calculate the MFI value automatically and store it.
