A retort clamp with two prongs is a laboratory tool used to hold glassware, such as flasks and test tubes, in place over a heat source. The clamp consists of a base, a screw mechanism, and two metal prongs that are used to grip the glassware. The base can be attached to a ring stand or tripod, while the screw mechanism allows the user to adjust the tightness of the grip.

The two prongs provide a stable and secure hold on the glassware, helping to prevent accidents or spills during heating or other laboratory processes. The retort clamp with two prongs is a versatile tool that can be used in a wide range of applications, including chemistry, biology, and other sciences. It is known for its stability, reliability, and ease of use.
