Laboy Glass Reducing Connecting Adapter from 14/20 Outer to 19/22 Inner Glass Joint Chemistry Lab Glassware

Size: From14/20 to 19/22

Features

• Design----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)).
• USE---When connection for two glass apparatuses with different joint size needed,the reducing 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.This adapter is used to connect two lab glassware with dissimilar standard taper joints from 10/30 to 14/20;
• DIMENSIONS----The glass reducing adapter is with 10/30 top outer joint and 24/40 lower inner joint
• HEAVY WALL ---This lab glassware is heavy-wall designed , made by hand-blowing according to ASTM E438 ,made of high-quality borosilicate glass and annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling,durable and reusable.
• 100% 90 DAY MONEY BACK GUARANTEE If you are not satisfied for any reason, simply return for a full refund, no questions asked. You have nothing to lose.Please also kindly understand glassware is fragile, even if we pack them carefully,it may be broken during the shipment ,if you receive the items in broken status,don't hesitate to contact us ,we will arrange free replacement or full refund.

Description

Size:From14/20 to 19/22 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.
