The humble wash bottle, an unsung hero in the laboratory, is an essential tool for a wide range of tasks. From rinsing glassware to preparing solutions, this versatile instrument is a testament to the ingenuity and simplicity of scientific equipment.
Wash bottles, also known as squeeze bottles, are commonly used for:
There are several types of wash bottles available, each designed for specific applications:
When selecting a wash bottle, consider the following factors:
Follow these safety guidelines when using wash bottles:
Avoid these common errors when using wash bottles:
1. What is the best material for a wash bottle?
The best material for a wash bottle depends on the liquid being dispensed. Polyethylene and polypropylene are suitable for most applications, while glass is more resistant to chemicals and heat.
2. How often should I clean my wash bottle?
Wash bottles should be cleaned regularly, especially if they are used to dispense sterile liquids or reagents.
3. Can I use wash bottles to dispense volatile liquids?
Volatile liquids should be dispensed using a special safety wash bottle with a pressure-relief valve.
4. How do I dispose of used wash bottles?
Dispose of used wash bottles in accordance with laboratory regulations. Rinse the bottle thoroughly and puncture the bottom to prevent reuse.
5. What are some creative uses for wash bottles?
Wash bottles can be used for various creative purposes, such as watering plants, painting, or cleaning hard-to-reach areas.
6. Are wash bottles reusable?
Yes, wash bottles are reusable if they are cleaned and maintained properly.
7. Can I use a wash bottle to dispense solvents?
Yes, but choose a wash bottle made of a solvent-resistant material.
8. How do I prevent air bubbles from forming in the stream of liquid?
Tilt the wash bottle at an angle to prevent air bubbles from entering the stream.
Story 1:
A lab technician accidentally filled a wash bottle with acetone instead of water. When she squeezed the bottle to rinse a beaker, the acetone dissolved the protective coating on the beaker, causing the beaker to crack.
Lesson: Always read the label before filling a wash bottle.
Story 2:
A student was using a wash bottle to rinse a flask when the bottom of the bottle fell out. The student was soaked in water, much to the amusement of everyone in the lab.
Lesson: Check the wash bottle for damage before each use.
Story 3:
A group of researchers were using a wash bottle to dispense a corrosive chemical. One of the researchers accidentally squeezed the bottle too hard, sending a stream of chemical into their eye.
Lesson: Wear appropriate PPE when using wash bottles.
