Frequently Asked Questions (FAQs)
1. What is the use of dispensing bottles in the laboratory?
Dispensing bottles in the laboratory are used to dispense precise amounts of chemicals, reagents, solvents, and oils from bottles or other containers. They are a necessary safety lab equipment that ensures accurate and controlled dispensing of substances.
2. What are the different types of bottles in the laboratory?
There are various types of bottles used in the laboratory, including wash bottles, reagent bottles, chemical bottles, and storage bottles. These bottles are made of different materials such as plastic, including PTFE, and may feature integrated spouts for easy pouring.
3. What plastic bottles are used in chemistry lab?
Polypropylene copolymer (PPCO) dilution bottles are commonly used in chemistry labs due to their excellent chemical resistance. They can withstand exposure to various substances, including high temperatures. Polysulfone (PSF) dilution bottles are also used for their clarity and accurate liquid level viewing.
4. What are plastic wash bottles used for in the laboratory?
Plastic wash bottles are primarily used for rinsing and washing glassware and plasticware in the laboratory. They can also be used for precise filling of volumetric flasks and as storage containers for solvents.
5. What are the different types of ml bottles?
Common ml bottle sizes used in the industry include nips or miniature (50 ml), half pint (200 ml), fifth (750 ml), liter (1,000 ml), and half gallon (1,750 ml) bottles.
6. What are three plastics that are used for labware?
Three plastics commonly used for labware are high-density polyethylene (HDPE), low-density polyethylene (LDPE), and polypropylene (PP). Other plastics used include polypropylene copolymer (PPCO), polymethylpentene (PMP), polyvinyl chloride (PVC), polyethylene (PETG/PET), and polycarbonate (PC).
7. Why are plastic containers used in the laboratory?
Plastic containers are used in laboratories for several reasons. They are lightweight and shock-absorbent, making them safer than glass containers. Plastic bottles are also easier to handle and transport. Additionally, plastic containers can be strong and shatterproof, reducing the risk of leaks and breakages.
8. Why is a wash bottle necessary?
Wash bottles are essential in laboratories as they hold key cleaning solutions like ethanol, methanol, and acetone. These solutions can build up pressure within the bottle, leading to hazardous solvent drips. Wash bottles provide a controlled and safe way to dispense these cleaning solutions during lab procedures.
