Sublimer, Micro Scale, with 2mm Glass Stopcock, 25mL Long-neck Flask

A micro scale sublimer is a device that is used for the purification of sublimable materials, which are materials that can be transformed directly from a solid state to a gas state without going through a liquid state. This device is particularly useful for purifying small amounts of these materials, as small as 100 mg. The micro scale sublimer consists of a 25 mL long neck flask, which is designed for small volume efficiency, and a cold finger condenser that is connected to the flask via a 24/40 standard taper.

The 25 mL long neck flask is a small volume vessel that is designed to hold the sublimable material during the purification process. The long neck of the flask is designed to prevent any of the material from escaping during the sublimation process. The cold finger condenser is used to condense the sublimated material back into a solid state, which can then be collected and used.

The 24/40 standard taper is a common size used for connecting various types of glassware in the laboratory setting. It ensures a secure and tight connection between the flask and the condenser, which is important for the sublimation process to be successful.

This micro scale sublimer is a useful device for purifying small amounts of sublimable materials. Its design, with a 25 mL long neck flask and a cold finger condenser connected via a 24/40 standard taper, allows for efficient and effective sublimation of the material.
