Standard Grade Regenerated Cellulose (RC) is a clear, flexible and sturdy dialysis membrane with a “looser” molecular selectivity. This economical membrane is ideal for a broad range of applications in which there is a significant size difference between the MW species being separated; including sample prep, desalting, buffer exchange, pH change, protein purification, etc. Offering a good chemical compatibility, Standard Grade RC can be used with dilute strong acids and bases, concentrated weak acids and bases, most alcohols and some mild or dilute organics, including DMSO. Standard RC can tolerate pH 2 – 12 and temperatures 4-121 °C

透析膜長度
全長＝［（樣品容量）／（體積／長度比）］＋（額外的10－20%）＋4 cm →計算您要使用多長的透析膜例如：透析膜平寬（FW）為16 mm，體積／長度比為0.79 ml/cm。欲透析5 ml樣品，則至少需約6.5 cm透析膜。但還需要額外的10－20%的長度（至少1 cm）使透析管填充空氣維持浮力。最後還需要頭尾各2 cm給透析夾使用。整個透析膜長至少需要11.5 cm長。
透析夾之選擇
Universal透析夾適用各種透析膜，Speatra/Por僅適用於RC透析膜 →透析夾詳細資訊 使用時選用大於透析膜平寬（Flat Width, FW）4－10mm以上的透析夾來進行密封。
