Chemglass Straight Adapter 14/20 Upper 19 mm OD 15 mm ID Bottom Opening Lot of 2

The Chemglass Straight Adapter with a 14/20 upper joint and a 19 mm OD / 15 mm ID bottom opening is a specialized glass component used for bridging different laboratory glassware sizes or for the introduction of probes, thermometers, or tubing into a reaction setup. Its straight-bore design ensures minimal obstruction for fluid transfer or instrument insertion. 

Core Specifications

• Upper Joint: 14/20 Standard Taper. This common microscale joint size allows for a vacuum-tight connection with other 14/20 components like condensers, addition funnels, or thermometers with matching ground glass joints.

• Bottom Opening: Features a 19 mm Outer Diameter (OD) and a 15 mm Inner Diameter (ID). This specific dimension is often used to fit into larger vessels or to accommodate specialized seals and bushings.

• Design: Straight Connector. The linear path is ideal for applications where an offset or bend would interfere with the placement of internal components or the flow of materials.

• Material: Fabricated from heavy-wall borosilicate glass (Type I, Class A), providing excellent thermal shock resistance and chemical durability against most laboratory reagents.

Common Applications

1. Thermometer/Probe Inlet: The 15 mm ID bottom is large enough to accommodate various thermometer adapters or sensor probes when paired with the appropriate 14/20 compression cap or bushing at the top.

2. Modular Assembly: Acts as a reducing or connecting sleeve in complex distillation or reflux setups, particularly when transitioning between microscale (14/20) and mid-scale laboratory glassware.
