很多客戶會問到多少樣品需要多長的透析袋或者選擇哪個寬度的透析袋，下面我們介紹下美國光譜醫(yī)藥（spectrumlabs）透析袋長度計算方法：

以下為關(guān)于這個方面的介紹：

Dialysis Tubing Calculator

The recommended tubing length is calculated based on the desired sample volume and the tubing flat width. This calculation also factors in additional length for closures and the headspace required for sample buoyancy.

Recommended Tubing Length （cm）:

9.89

Volume: 1 ml, Width: 8 mm

Note: To optimize dialysis efficiency, it is recommended to select a flat width such that the resulting in tubing is 15 - 20 cm long.

A flat Width of 8 mm is recommended for best performange with a volume of 1 ml.
