Features
Description
Laboy Glass reducing adapter , with smaller outer joint at top and larger inner joint at bottom, is used to connect dissimilar standard taper ground glass joints. Standard Taper Ground Glass Joints are interchangable. For either frosted, presicon-ground standard taper joints (same size), the inner ground surfaces (male joint) make a good seal with the outer(female joint)). The joint size is described by the form A/B. The first number A represents the outer diameter (OD) in millimeters (mm) at the widest point of the inner (male) joint and the second number B represents the length of the joint. For example, a 14/20 joint is 14 mm wide at the top (the widest part) and is 20 mm in longth. The joint has a standard taper 1: 10, any two joints (male and female) with the same outside diameter (A)can fit into each other , no matther how lenght the joints are. For example, a 24/40 (US standard size) joint on a condenser will fit into a 24/29 (European standard size)flask but the ground glass joint will protrude (40 - 29) 11mm into the flask. When connection for two glass apparatuses with different joint size needed, the connecting adapter (reducing adapter or enlarging adapter)is availiable to place between to connect them. The standard plastic joint clips or metal clips are placed arround the joints to hold them in place. The Laboy glass reducing adapter is made by hand-blowing and made of high-quality borosilicate glass (similar to Pyrex) that can be heated directly in an open flame and will withstand typical laboratory thermal variations in synthesis processes like heating and cooling.
