- Peteri-dishes: Petri-dishes are disposable clear plastic dishes with a cap that are used for many science experiments and bacteria growth. A thin layer of nutrient agar in a petri-dish is enough for growing bacteria.You can see the bacteria colony shapes and count them without opening the lead of the petri-dish. Since petri-dishes are clear, you can see the bacteria from either side of the dish.eteri-dishes: Petri-dishes are disposable clear plastic dishes with a cap that are used for many science experiments and bacteria growth.

- The unique design of this cup enables drinking without having to tilt the head. The Nose Cut-Out Beaker is ideal for people who choke easily or cannot tilt their heads back due to neck injuries. The cup has been shown to be particularly useful for children who have cerebral palsy. The cut-out fits around the nose when drinking. The 73mm (2) wide opening allows the therapist to observe the liquid going into the clients mouth. The blue model is made of unbreakable plastic, which reduces the chance of injury as a result of sharp shards.

Gas syringe Gas syringe. A gas syringe is a piece of laboratory glassware used to insert or withdraw a volume of a gas from a closed system, or to measure the volume of gas evolved from a chemical reaction. A gas syringe can also be used to measure and dispense liquids, especially where these liquids need to be kept free from air.

What is a watch glass and how is it used? exists and is an alternate of . A watchglass can be used as a beaker cover, but you can also place small amounts of chemicals on it and then heat it (for example, to evaporate some water from a wet chemical). A watch glass is a circular, slightly concave piece of glass used in chemistry as a surface to evaporate a liquid, or as a cover for a beaker.
