DADAKEWIN 193mm Drying Tube Straight Glass 24/29 Joint Borosilicate

Description

Product Overview

The DADAKEWIN 193mm Drying Tube is a straight glass tube designed for air‑drying applications in scientific environments. Made from Borosilicate 3.3 glass, it offers a low thermal expansion coefficient—about one‑third that of ordinary glass—ensuring resistance to high temperatures and chemical attack. The tube features a thick upper section for added mechanical strength and a thinner lower bulb that serves as a desiccant reservoir. It terminates in a standard 24/29 ground‑mouth joint, allowing seamless connection to standard lab glassware.

Usage

This drying tube is perfect for professional laboratories, science classrooms, and even home hobbyist setups where moisture‑free gas streams are required. It can be placed inline with gas delivery systems to remove moisture before the gas reaches sensitive reactions or instruments. Users can stack multiple tubes in series and load different desiccants to achieve higher drying efficiency. Its robust construction makes it suitable for routine heating, cooling, and exposure to a wide range of chemicals.

FAQ

Can I use this drying tube with gases other than air?

Yes, the tube is compatible with any inert or reactive gas streams that require moisture removal, provided the gas temperature stays within the glass’s tolerance range.

How do I improve the drying performance?

For higher drying efficiency, connect two or more tubes in series and load different desiccants (e.g., calcium chloride followed by molecular sieves) in each bulb.

Is the tube reusable after cleaning?

Absolutely. The tube can be cleaned with appropriate solvents, thoroughly rinsed, and dried before re‑loading fresh desiccant.

What is the maximum temperature the tube can withstand?

Borosilicate 3.3 glass tolerates temperatures up to approximately 500 °C, making it suitable for most laboratory heating applications.
