Erlenmeyer flasks DURAN® Super Duty Narrow neck, 500 ml, 10 Piece(s)

Notes for use:

To avoid thermal stresses in the glass, uniform and slow heating of Super Duty products is recommended. When working at very high temperatures, or if rapid temperature changes are expected, standard DURAN^® beakers and Erlenmeyer flasks should be used, as these have excellent thermal shock resistance. However, their mechanical sturdiness is limited compared with the Super Duty range.
