The Teclu burner provides better mixing of air and fuel and can achieve higher flame temperatures than the Bunsen burner. [9] [10] Meker burner – The lower part of its tube has more openings with larger total cross-section, admitting more air and facilitating better mixing of air and gas. The tube is wider and its top is covered with a wire grid.
Tygon R-3603 Laboratory Tubing is commonly used in chemical laboratories. It is often used in incubators and as a replacement for rubber tubing for Bunsen burners. This material is produced in vacuum sizes and can withstand a full vacuum at room temperature. It is a thermoplastic PVC-based material with plasticizer. [3]
The short tube and hose barb effectively act as an adapter over which the end of a thick-walled flexible hose (tubing) can be fitted to form a connection to the flask. The other end of the hose can be connected to source of vacuum such as an aspirator, vacuum pump, or house vacuum. Preferably this is done through a trap (see below), which is ...
Splints are typically long, thin strips of wood, about 6 inches (15 cm) long and ¼ inch (6 mm) wide, and are consumable but inexpensive. They are typically used for tasks such as lighting bunsen burners, as the length of the splint
The tube is wider and its top is covered with a plate mesh, which separates the flame into an array of smaller flames with a common external envelope, ensures uniform heating, also preventing flashback to the bottom of the tube which is a risk at high air-to-fuel ratios and limits the maximal rate of air intake in a Bunsen burner.
A pipeclay triangle is a piece of laboratory apparatus that is used to support a crucible being heated by a Bunsen burner or other heat source. It is made of wires strung in an equilateral triangle on which are strung hollow ceramic, normally fire clay, tubes. The triangle is usually supported on a tripod or iron ring.
