DURAN® Flat Bottom Flask, NS 24/29, 250 mL
Flat bottom flasks are a form variant of the round flasks and have a flattened bottom on which they can stand. The standard ground joint allows a precise connection to other ground joint components such as columns, thermometers, drip funnels, ground joint plugs, etc. Because of their shape, standing pistons are only suitable for pressureless work.
Features and Benefits:

• Complies with DIN ISO 4797
• Tight closure due to standard ground joint
• Fired-on, highly durable white print
• Flat base means flasks can be set down without a supporting ring
