The long neck culture flask is basically an Erlenmeyer flask to which a long straight, rimless neck of heavy tubing has been added.

  • Very good chemical resistance
  • High temperature resistance
  • Minimal thermal expansion giving relatively high resistance to temperature changes

Long neck erlenmeyer flask is ideal for shaker cultures. The longer necks reduce the amount of splashed solution reaching the closure.

Their uniform wall thickness provides the proper balance between mechanical strength and thermal shock resistance.

For convenience, these flasks include a marking spot. The approximate neck ext.Ø is 38 mm.
