This Corning® kit is similar to No. 6949E, as many of the same standard laboratory experiments can be performed with this kit. The kit’s PYREX® components all use 19/22 Standard Taper joints for standardization. Note in particular the inclusion of a 250 mL flask with side tubulation, which is useful when performing steam distillations or experiments requiring an air bleed. This kit contains a three neck boiling flask to enable…
