Methods and apparatus for preventing sample loss |
| abstract |
A reduction of sample loss from a container open to atmosphere, and including liquid trifluoroacetic acid (TFA), is carried out by a variety of methods each of which reduces creep of TFA up the walls of the container. In one method, particularly applicable to microtitre plates, each container or well is sealed by a cap which is retained by a strap (FIGS. 4 and 5 ). In another method the top of the container is formed with a downwardly pointing entrance tube, in the form of an unspillable inkwell (FIG. 2 ), where the container is a screw top vial, the entrance tube is sealed around the top of the neck of the vial (FIG. 9 b ). |
