Hill Top Chamber斑試器最先出現(xiàn)在上海攬寶儀器設(shè)備有限公司。
]]>Cliantha Hill Top Chamber斑試器被廣泛用于化妝品、香水、薄膜、織物、肥皂、洗滌劑、化學(xué)品以及其他可能直接或間接影響或涉及皮膚的產(chǎn)品領(lǐng)域。
Hill Top Chamber斑試器是一種獲得專利的封閉型皮膚傳遞系統(tǒng)，可用于多種用途，包括：
- 預(yù)測(cè)性斑貼測(cè)試
- 診斷性斑貼測(cè)試
- 皮膚水分評(píng)估
- 皮膚微生物菌群研究
- 動(dòng)物身上的斑貼測(cè)試
系統(tǒng)設(shè)計(jì)/方案
Hill Top Chamber斑試器系統(tǒng)的基本組成部分是一個(gè)模制的塑料腔室，具有足夠的靈活性足以貼合皮膚的輪廓。該腔室有一個(gè)獨(dú)特的雙環(huán)，由一個(gè)外環(huán)和一個(gè)內(nèi)部的柔性法蘭組成，與皮膚表面緊密貼合，以提高閉合性。在腔室里，一個(gè)無紡布的Webril?墊片容納試驗(yàn)樣品。腔室被夾在方形防粘紙和半封閉的低過敏性膠布之間，隨時(shí)可以使用。Hill Top腔室可以單獨(dú)提供，也可以以帶有任何數(shù)量小室的多體條狀形式提供。幾乎任何大小或形狀的腔室都可以定制生產(chǎn)。也可提供單獨(dú)的塑料腔室，帶或不帶Webril?墊片。
腔室組成
Hill Top Chamber斑試器采用殼牌石油公司的產(chǎn)品 Kraton? G-2705 制造。 Kraton? 滿足或超過當(dāng)前 USP 對(duì) VI 類聚合物的物理化學(xué)和生物測(cè)試的要求。該室柔軟且有彈性，從而在測(cè)試材料和皮膚部位之間提供粘合力。 Kraton? 材料已獲得 FDA 批準(zhǔn)使用?？筛鶕?jù)客戶需求提供其他塑料。 Hill Top Chamber 斑試器系統(tǒng)采用 Durapore? 背襯，這是一種“絲狀”膠帶，采用 3M 制造的無乳膠、低過敏性粘合劑，具有高強(qiáng)度和粘合力。 Webril? 襯墊為 100% 純棉材質(zhì)。
