These kits are ideal for standard laboratory experiments.

• Ideal in teaching and research applications in which assembly time is at a premium

Chemistry kits 32643-500 and -000 include 190 mm (7¹/₂") distilling column; 190 mm (7¹/₂") West condenser; 25 mL, 50 mL, 100 mL, 250 mL, and 500 mL round bottom boiling flasks; 125 mL pear-shaped separatory funnel; one glass stopper; bleed tube; adapter tube with thermometer opening; rubber thermometer holder; and vacuum, three-way, and Claisen connecting tubes.

Chemistry kit 89091-020 includes 190 mm (7¹/₂") distilling column; 190 mm (7¹/₂") West condenser; 25 mL, 50 mL, and 100 mL round bottom boiling flasks; 250 mL round bottom boiling flask with side tubulation; 500 mL three-neck round bottom boiling flask; 125 mL pear-shaped separatory funnel; and two glass stoppers. The side tubulation aids in performing steam distillation or experiments requiring an air bleed. The three-neck flask enables distillation while stirring and adding other compounds.

Chemistry kit 32640-002 may be used for fractional and vacuum distillation; reaction with gas evolution, preparation, or recovery; simple reflux; and reflux with addition. Kit includes Leibig condenser column; cold finger condenser; 100 mL, 250 mL, and 500 mL round bottom boiling flasks; 100 mL graduated separatory funnel; one glass stopper; thermometer with rubber holder; reaction vessel tube; drying tube; adapter outlet tube; distilling tube adapter; and two connecting tube adapters.

Microscale chemistry kits 89091-024 and -022 are ideal for performing experiments covered in Mayo, Pike, and Butcher text "Microscale Organic Laboratory" published by John F. Wiley. Kit 89091-024 includes 7/10 and 14/10[ST] jacketed condensers; 7/10 and 14/10[ST] air reflux condensers; Hickman Still head; 10 mL Erlenmeyer flask; Claisen three-way connecting adapter head; capillary gas delivery tube; gas chromatograph collection tube; drying tube; 1 mL and 2 mL Craig recrystalllization tubes; and 0.1 mL, 0.3 mL, 1 mL, 3 mL, and 5 mL conical reaction vials.
