The Quickfit® Microscale Chemistry Kit was designed to perform organic chemistry experiments, but on much smaller scale. This reduces your cost of everything involved, smaller amounts of reagents, lower disposal costs and less clamping equipment. Most standard organic chemistry sets may be performed using this set. The main benefits are: cheaper (reduced solvent costs), safer (smaller amounts of chemicals and no Bunsen burners required), quicker (reduced times for experiments), versatile (many assemblies can be constructed reflux, distillation, fractional distillation etc.) and easy to assemble (combination of standard Quickfit® ground glass joints and sealing 'O' rings and plastic screwcaps). Dimensions (L x W x D): 40 x 25 x 20 cm (unpacked). Contents: • Air condenser • Drying tube • Still head • Jacketed condenser • Thermometer adapter • 25 mL Pear shaped flask • 10 mL Pear shaped flask • Bag of spare caps, seals and 'O' rings • 25 mL Round bottom flask • 10 mL Round bottom flask • 10 mL Erlenmeyer flask • 25 mL Erlenmeyer flask • Receiver
