Wide neck conical flasks that make pipetting, filling and adding powder easier:

• Wide neck borosilicate glass 3.3 conical (Erlenmeyer) flasks, ten to a pack and reusable
• Wider mouth for easier pipetting, filling and powder addition
• Conical shape suited to manual swirling and orbital shaking
• Beaded rim for pouring
• Graduations in white as an approximate volume guide, with a writing patch to mark contents
• High resistance to thermal shock for mixing and heating, with resistance to acids, chlorine, bromine, iodine and organic substances

Powder additions, pipetting and filling all go more easily through a wide mouth, which is what sets these conical (Erlenmeyer) flasks apart from a standard narrow-neck flask. They are made from borosilicate glass 3.3 and suit laboratories that mix, heat and store solutions, with ten to a pack so replacements are always on the shelf.

The conical shape suits swirling by hand or shaking on an orbital shaker, and the beaded rim helps with pouring. White graduations give an approximate volume, and the writing patch gives space to mark the contents.

Borosilicate glass 3.3 has high resistance to thermal shock and excellent thermal stability, which suits mixing and heating. It also resists water, neutral and acid solutions, strong acids, chlorine, bromine, iodine and organic substances, and the flasks can be reused after cleaning.
