IBEX SCIENCES supplies premium Screw Neck Glass Adapters from their scientific equipment hub in Lahore, Pakistan. [1]
A screw neck adapter (also known as a thermometer adapter) is a vital piece of ground-joint glassware. It features a threaded plastic cap at the top that allows you to safely insert, adjust, and seal a thermometer or fluid tube inside a boiling flask setup without causing a vacuum leak. [1]
Key Technical Specifications
The screw neck adapters sourced through the IBEX SCIENCES Glassware Network feature standard high-end laboratory designs:
-
- Premium Borosilicate 3.3 Glass: Blown from heavy-duty, heat-resistant glass to withstand high-temperature distillation reactions without cracking. [1]
- Adjustable Fitting: Equipped with a threaded plastic or rubber screw cap and an internal O-ring seal. This lets you slide a glass thermometer up or down to measure exact vapor levels, then lock it securely in place. [1]
- Standard Joint Sizes: Available in popular taper sizes (such as 14/23, 19/26, and 24/29) to guarantee a flush, airtight seal with standard round-bottom flasks and condensers. [1, 2]
Typical Variations
-
- Straight Screw Neck Adapter: Features a single top screw thread sitting vertically over a lower ground-glass cone piece.
- Offset/Angled Adapters: Features a multi-neck layout where one branch is a standard ground socket and the other branch is a dedicated screw cap port for probes. [1]
