Erlenmeyer flasks Super Duty DURAN® narrow neck DWK

 

Narrow Neck. Due to the increased quantity of glass, the mechanical sturdiness is significantly improved compared to standard DURAN® beakers and Erlenmeyer flasks. A further product advantage is the strengthened (tooled) rim, which also provides additional impact resistance and considerably reduces the risk of breakage.
This extension to the DURAN® product range therefore offers the user optimum safety when working with glassware that is subject to heavy mechanical loading, even when it is cleaned and used frequently. Super Duty glass vessels also work out cheaper in the long run – thanks to the increased impact resistance.

Product advantages:

• Increased mechanical sturdiness due to increased uniform wall thickness
• Reinforced, sturdy rim
• Uniform wall thickness distribution
• Proven DURAN® properties
• Type1 glass / neutral glass as per USP, EP and JP
• Autoclavable / sterilisable
• With retrace code (Batch certificate via Internet)
• Easy-to-read scale, fired-on, extremely durable printing

Application note:
To avoid thermal stressing of 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 are characterized by excellent thermal shock resistance. However, the mechanical sturdiness of these DURAN® standard products is limited compared with the super duty range.
