What is an Evaporation Dish Used for?

An evaporation dish is a crucial piece of equipment used in laboratories and other testing environments to contain samples of liquids that require evaporation. This low dish can safely hold acids, chemicals, and small samples, which are then heated to induce evaporation. This blog post will provide you with a brief overview of what an evaporation dish is and what it is used for.

What is an Evaporation Dish?

Commonly made from borosilicate glass or porcelain, evaporation dishes hold samples so that when evaporation occurs, the remaining residue (a concentrated solution) is contained. These dishes are rounded with a small pouring spout so that any liquids can be removed easily and safely, as well as being heat-resistant, open dishes that can withstand high temperatures.

Evaporating dishes are typically small but can be made in broader and larger configurations to accommodate larger samples. The key feature of a dish must allow for a large surface area, which causes evaporation easier and faster. Additionally, they are often referred to as watch glasses because of their design.

What is an Evaporation Dish Used for?

Evaporation dishes can be found in all testing laboratories and used for various applications, depending on what the scientist needs to do. It is worth noting that evaporation dishes are not marked with volumes because they are not usually used directly as measuring instruments. 

Evaporation

As we have already mentioned, the critical function of an evaporation dish is to hold solutions that need to be evaporated. These dishes are made to evaporate pervasive substances and safely contain potentially harmful samples before, during, and after the process. The dish will be heated to high temperatures over a flame or in an oven during the evaporation process. Therefore dishes are made to be highly resistant to high temperatures and thermal shock.

Miscellaneous Uses

Although evaporation dishes are not frequently used as measuring tools, they can be. Before a sample is evaporated, the dish is weighed. Once evaporation has happened, the dish is weighed again, and the weight of the evaporated substance can be calculated. 

Evaporation Dishes with XRF Scientific

XRF Scientific designs and manufactures evaporation dishes in various capacities, and we also offer custom pieces to suit your applications. Our dishes are made with pure platinum and high-performance alloys to ensure high performance and reliability. We use gold alloys, rhodium alloys and iridium and all alloy-based materials are screened before being accepted to ensure they are entirely pure before being used in production.

The standard details of XRF Scientific evaporation dishes include capacities of 55 to 150cc, diameters of 59 to 69mm, depths of 22 to 40mm and estimated weights of 28 to 50g. However, we are always happy to discuss customer requirements and support with the design and implementation of products.
