小弟還是覺得"實驗室用途"的Tygon® Laboratory Tubing比較適合水冷使用，
因為它的特性如下：(尤其是黃色字體部分)
• Outstanding chemical resistance (抗化性佳)
• Lot-to-lot consistency for reproducible results
• Increases productivity in peristaltic pumps -- outlasts other clear tubing 2 to 1 (水流率佳)
• Ideal for condensers, incubators, desiccators, gas lines and drain lines

其實我打電話問過Tygon(在Akron, OHIO..離我這不到2小時)
它們說material都差不多耶...當然R 3603是比較專業的!
但是Chemical resistance 機乎是identical...
..but..remember..."free is always a good one!"
