水滴形狀分析儀 - DSA100

全世界通用,高品質的儀器,用於分析潤濕性和塗佈方法

我們的水滴形狀分析儀- DSA100在固體表面分析潤濕性附著力上擁有高質量的系統來解決幾乎所有任務。從接觸角基本單位的精確測量到全自動專家儀器序列測量表面自由能,我們都有合適的DSA100型號來符合您的需求。我們完全相匹配的獨立,靈活和可靠的組件的來配合您的表面和流程

固體和液體的綜合分析

我們DSA100測量液體的表面張力使用懸滴法Pendant Drop。其結果可用於分析固體的潤濕和液體屬性之間的關係。

其結果有助於提供一張界面接觸的科學圖像例如可用於 : 以優化塗層的粘合性和長期穩定性。

其它用於測量液體 - 液體之間的界面張力解決方式,測量高壓和表面流變學使用DSA100這一個普遍性的通用儀器來做研究
