Necklengths may be designated “short” or “long”.6.2 The top shall be strengthened and finished.6.2.1 Vial finish or tooled top6.2.2 Beaded rim or ring neck6.2.3 Standard taper ground glass joint in compliance withSpecification E6766.2.4 Ball and socket ground glass joint, in compliance
17、withSpecification E6776.3 Wall thickness minimums are given for all flasks inTable 1.6.4 Flat bottoms shall be in a plane perpendicular to thevertical axis through the neck of the flask.6.4.1 The bottom of the flask shall be flat, however veryslight concavity is permitted. The flasks shall stand ver
18、ticallywithout rocking or spinning when placed on a level surface.6.4.2 The diameter of the flat base of the flask shall be 45 to65 % of the maximum external diameter.6.4.3 Type I, Class 3 flat-bottomed flasks shall have awoven wicker insulation collar around the neck.6.5 Round-bottomed flasks shall
