A retort clamp cross pattern rotatable aluminum is a type of laboratory equipment used to secure a retort flask in place during distillation experiments. The clamp is made of aluminum and has a cross-pattern design to provide stability and support for the retort.

The rotatable feature allows the retort to be easily adjusted and positioned at different angles as needed. This can be useful in cases where it is necessary to access the contents of the retort from different directions. The aluminum material offers durability and resistance to corrosion, making it suitable for use in various laboratory environments.

This type of retort clamp is commonly used in chemistry and chemical engineering experiments and is an important tool for conducting accurate and precise distillation processes.
