Preparation of BTT & ETT Solutions
Crystalline BTT (0234) and ETT (0237) are provided in three pack sizes (1g, 10g and 25g) for dilution to customers' required concentrations in whatever synthesiser bottle is appropriate. Typical dilution information is given below (these examples equate to routine bottle sizes and concentrations, however, obviously a range of pack sizes is provided to give customers flexibility in this).

To prepare the solution simply weigh out the desired amount of product into your instrument bottle and dilute by adding filtered, anhydrous acetonitrile (Diluent, 4050) as indicated. Ensure that the solid is entirely dissolved prior to use.
Remember that a full range of synthesiser-ready bottles of BTT and ETT are also available for Expedite, ABI and MerMade instruments.
