For example, a staple experimental apparatus for biological labs is the PCR Machine, which replicates and amplifies DNA so that scientists can study it more easily. Chemistry labs are more likely to own equipment like chemical fume hoods, which are large ventilated boxes that chemists use to protect themselves from explosive and toxic chemicals.

Scientists use analytical equipment to generate data from the experiments they perform so that this data can be published. Analytical equipment varies with the experimental equipment used.

For example, biologists use spectrophotometers to determine the concentrations of DNA that they have in order to sequence it. Chemists need very precise scales so that they can weigh out their products to determine the all-important chemical yield of their reactions.

The bulbed bottom allows the heat to distribute through the liquid more evenly.

The advantage to the Erlenmeyer Flask is that the bottom is wider than the top so it will heat quicker because of the greater surface area exposed to the heat. They are usually made of glass. This may be necessary to dry a solid completely. By grinding solid chemicals into smaller pieces, the solid may dissolve or react with other chemicals more quickly. They come in many different sizes, depending on the item being cleaned. Slides In a biology lab, cells are gently smeared onto a glass slide, treated with a fixative so that the cellular component is seen clearly.
