Brochure

Standard Grade Regenerated Cellulose (RC) membrane 為透明、富有彈性且耐用的透析膜,擁有極高的化學耐受性,可用於低濃度的強酸強鹼溶液、高濃度的弱酸弱鹼溶液、大多數的醇類和稀釋的有機溶劑 (包括DMSO) 並可在溫度 4-121 °C 和 pH 2-12 的環境下進行實驗。

 

Standard Grade RC membrane 用途廣泛,適合用於將分子量差異大的樣品進行分離實驗,包含樣品製備、去除鹽類、置換緩衝溶液、調整pH 值與蛋白質純化等等實驗。

 

Spectra/Por ® 1 - 5 Standard RC Dialysis Tubing 為方便使用者保存,因此以乾燥的形式包裝出貨。此類型透析膜一卷為 15 或 30 公尺,依使用者需求可自行裁切成合適的長短,對於實驗需求量大的人,是較為經濟型的包裝。大部分乾燥的透析膜在實驗前需浸泡過濾水30分鐘以去除保濕劑-glycerin。若乾燥的透析膜不帶有glycerin則實驗前可不必進行此步驟。
