有谁知道DNA彻底酸解成碱基的具体操作吗? 文献上一般描述：Ten milligrams of salmon testes was hydrolyzed in 0.5mL of 95% formic acids at 170 ◦C for 30 min in two glass tubes(15 cm×4mmo.d.×2.5mmi.d.) with two ends sealedaccording to procedures in literatures [11,19]. When the hydrolysates were lyophilized, the lyophilized residues were dissolved in10mL mobile phase. The final solutions were filtered through a 0.4m syringe cellulose acetate filter prior to analysis。我这样做的怎么老是崩开呢，文献里的玻璃管(15 cm×4mmo.d.×2.5mmi.d.)是专门用来水解的瓶子吗，在哪里可以买到呢？我用的是1.5mL的小瓶子承受不了呢
