 HAAKE CaBER : 유체용 신장 유변 물성 측정기
제조사명
Thermo Scientific
품목명
[A] 유변 물성 측정기(Rheometers)

전단 상황 (Shearing flow) 하에서 재료의 유동거동은
실제 신장 흐름상 (Extensional flow) 하에서의 재료의
유동거동과 크게 차이가 날 수 있음. 세계 유일의 액체 및 용액 전용 HAAKE CaBER-1 Extensional Rheometer는 회전 점도계에서는 측정이 불가능한 재료의 신장 흐름 거동에 관한 중요 정보를 제공.

   
 


The Thermo Scientific HAAKE CaBER is the only commercially available extensional rheometer to quantify elongational properties of fluids or semi-solids.
