Glass Stopper (Cold Trap) 24/40

A Glass Stopper (Cold Trap) 24/40 is a type of laboratory glassware used in distillation, filtration, or condensation setups. It combines two key elements: the cold trap function and a 24/40 glass joint size.

Here's a breakdown of the features:

1. Cold Trap Function:

• The cold trap is a device used to prevent unwanted vapors, liquids, or condensates from contaminating other parts of the system. It works by cooling vapors to a temperature below their condensation point, causing them to condense into a liquid or solid that can be collected or drained off. This is especially useful when handling volatile or harmful substances, as it prevents them from escaping into the atmosphere.
• A cold trap often involves a chilled coolant circulating through the trap to absorb heat and facilitate condensation.

2. Glass Stopper:

• The stopper refers to a removable cap or closure made of glass that seals a vessel or joint in a laboratory system. In this case, the stopper ensures an airtight seal to maintain the integrity of the system and prevent leaks.
• The stopper also serves as a convenient way to access the contents of the trap or disconnect it from other parts of the apparatus.

3. 24/40 Glass Joint:

• The 24/40 refers to a specific size of ground glass joint. The first number (24) refers to the outer diameter of the joint in millimeters, while the second number (40) refers to the length of the joint (in millimeters). This is a common size for laboratory glassware and indicates that the glass stopper or joint will fit into compatible 24/40 female or male joints.
• The ground glass joint provides a tight seal when connected, ensuring that there are no leaks in the system.

4. Usage in Laboratories:

• The Glass Stopper (Cold Trap) 24/40 is used in distillation apparatus, where it captures vapors before they can enter other parts of the system, like a condenser or collection vessel. It's also common in reaction setups where it's important to protect sensitive equipment or collect condensed vapors safely.

In summary, a Glass Stopper (Cold Trap) 24/40 is a critical component in laboratory systems for trapping vapors or condensates, ensuring efficient and safe processing of volatile substances. The 24/40 size ensures compatibility with a wide range of laboratory equipment.
