Instron 的 CEAST 模組化熔融多重配重測試儀是熔體流動測試的重大發展。單一測試可對相同試片施加一個、兩個或三個砝碼的負載（以遞增或遞減順序），輸出結果包括剪切靈敏度或流量比（能用於更廣泛流變研究的首要數據）和試片流變曲線的第一低剪切速率點。
- 根據 ISO 1133和 ASTM D1238 Procedures A、B、C 和 D 執行測試
- 獨特可選的荷重元，能準確施加壓縮材料的力量，最多可達 750 N，以增加結果的重複性
Thermoplastic materials are processed as fluids under the effect of temperature and pressure. The ability of melted materials to flow under pressure at set temperatures has a fundamental importance in polymer science and technology. The Instron® line of CEAST Melt Flow Testers are specifically designed for the easy and accurate measuring of the flow properties of plastics according to the relevant ISO and ASTM international standards. The renewed line of CEAST melt flow testers includes four different models: MF10, MF20, MF30, and MF50. These range from manual determination of MFR (melt flow rate) to semi-automated MVR (melt volume rate) measurements involving multiple weight tests The versatile CEAST MF20 and MF30 are single-weight systems that are ideal for performing tests according to ISO 1133 and ASTM D1238 Procedures A, B, and C. Compliant with ISO 1133-2 requirements, they can perform reliable tests on commodity materials, as well as on the most temperature- and moisture-sensitive special grade materials. Many different options are available: from primary test inspection to integrated test automation solutions.

Flow properties of molten plastics are a critical characteristic requiring good knowledge and control. The Instron® Melt Flow Testers are specifically designed for easy and accurate measuring of the Melt Mass-Flow Rate (MFR) and the Melt Volume-Flow Rate (MVR). CEAST Melt Flow Testers range from systems that perform a simple manual test procedure to semi-automated testing systems performing multiple weight tests.
