Laboratory safety rules

A laboratory is a place where what you read in the text books can actually be felt. As conducting experiments is not the same as reading from a book, every care and precaution should be observed while working in a lab. Following the below mentioned safety rules can prevent a lot of accidents and mishaps.

Clothing

When working in a lab, it is important that you pay attention to the clothes you wear. Listed below are points that you need to consider when in a lab.

  • Tie up long hair.
  • Do not wear extra loose and baggy clothes.
  • Never enter a laboratory wearing dangling accessories
  • Always wear a lab coat.
  • Safety gear like safety goggles and gloves should always be worn while working in the laboratory.
  • Contact lens should never be worn in a laboratory.
  • Any type of open shoes shall not be worn.
  • Do not wear clothing made of fabric that catches fire easily.
  • Use masks whenever necessary.

Food and beverages

Food and beverages are prohibited in the laboratory. Also, it should be remembered that laboratory glassware is for conducting experiments only; they should never be used as containers for food.

General guidelines

  • Keep your working desk neat.
  • Do not touch chemicals that you do not know of or do not require.
  • Handle lab equipment carefully.
  • Do not inhale gases as they can be dangerous.
  • Do not pipette with your mouth.
  • Use chemicals judiciously.
  • While heating or pouring acids maintain a good distance with the burner and acid bottle respectively.
  • Maintain caution while using flammable substances especially near heat.

What to do in case of accidents and mishaps

While some chemicals may not pose any hazard to you, some can be really dangerous and have carcinogenic ingredients. Therefore, it is always advisable to take every care while handling chemicals. If you spill some chemical, immediately wash your hands with water and inform the person in charge. Check whether the chemical is toxic or not, if it is toxic you might require medical help. Also, handle acids carefully as they can cause permanent damage.

In case a fire breaks out, do not panic and inform everyone about it. Do not try to extinguish the fire all by yourself, take help of the person in charge of the lab. It’s better to be safe than sorry!

Lab Equipment (Burettes and pipettes) – Making Science More Fun

Contrary to what many people believe, especially those who haven’t been in close association with it, science is a lot of fun. The most important thing that Science has taught us is that everything that happens has a logical explanation to it.

In order to make us understand things better, laboratories and lab equipment have played a crucial role.

Burette and pipette

Burette and pipette are lab equipment used in the volumetric analysis of an analyte. Burette is a glass tube having a tap at the bottom. Pipette is also a glass tube that has a bulge in the middle. They both have gradations to measure the quantity of chemical substances. While burette is used to deliver a chemical solution with a known concentration into a flask, pipette is used to measure the quantity of the analyte- the chemical substrate whose concentration is to be determined.

What are they used for?

They are both used for Titration.

Titration

Titration or Titrometry is a common laboratory procedure used in the quantitative analysis of an analyte (a chemical substrate) which is usually an acid in acid base titration.

Titrant- The solution with the known concentration is called the titrant. The burette contains the titrant which is slowly delivered into the analyte present in the conical flask.

Titrand-The chemical substrate with unknown concentration is called titrand. The titrand is present in the flask.

End Point/ Equivalence Point-End point or equivalence point is the point at which there is complete neutralization of eth acid with the base. To measure the end point different indicators are used that change color. The change in color is referred to as the end point.

After filling the burette up till a certain mark, and placing a flask underneath that contains the analyte (the quantity of which is measured with a pipette), indicator is added to the solution present in the flask to measure the end point. In acid base titration, the end point is determined with the help of an indicator solution or Ph paper. A titration curve is plotted, and the concentration of the titrand is determined.

Who says science is boring, you just need to devote some time to realize how fascinating it can be.
In Marie Curie’s own words “Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.”

Buying microscopes for school science lab

Microscopes are practically useful science laboratory equipment. They are used widely in research laboratories, scientific labs, pathological laboratories, and school science laboratories. Microscopes are crucial for varied diagnostic applications. They provide high quality detail of the specimen under study. The specimen can include flowers, insects, grass, vegetables, fruit skins, and many other things.

Microscopes come in a huge variety. There are medical microscopes, laboratory microscopes, stereo inspection micro scopes, and educational microscopes-each serving a specific purpose. Kid’s microscopes or educational microscopes are popularly used in schools. They are a great means to encourage kids’ interest in science. Microscopes allow kids to see the world in a unique and interesting way, in a way they have never seen it before.

Educational microscopes take science out of textbooks and bring it into the real world for kids to help them understand things in a much better and easier way. Microscopes allow kids to have their first taste of the microscopic skills. With the help of their teachers and parents at home kids are able to see blades of grass, leaves, flower petals, fruit skins, small insects, vegetables, tiny life forms in pond water, and many other objects and living organisms. Children take delight in examining the tiny objects. Microscopes are a great way to supplement their science studies and at the same time foster independent leaning.

Here are few tips for buying microscopes for school science labs:

When buying microscopes for kids, your first important consideration should be that it is light in weight, portable, comfortable, and user-friendly. There are ergonomic microscopes where all the features are within finger reach.

The next important concern when choosing the microscope is quality. Buy a top quality microscope that can bear vigorous daily use.

Microscopes come with different types of clarity and magnification. It is advisable to choose the microscope that promises high resolution imaging. A good microscope features a high point eyepiece that provides high resolution flat field imaging over a big specimen area. There are advanced models that provide parallel optical path from the image and yield in flat field imaging and high clarity.

Although there are many different types of microscopes, the two most common types are the stereo and compound microscopes. Stereo scopes are suitable for looking at the details of larger things, such as stamps or buttons. They feature a light on both the bottom and the top of the viewing area for viewing objects that are not transparent. Stereo scopes don’t require the use of slides. Compound scopes have a single light on the bottom of the viewing area. These devices are suitable for viewing things that are invisible to the naked eye. There are some microscopes that are both compound and stereo.

Another important consideration to be bear in mind when buying microscope is the light source. Basic microscope models illuminated the viewing area by reflecting light onto a mirror. Today, advanced models feature built-in light, mostly an LED. Built in light source allows for optimum viewing. Plus, LED is better to other light sources as it doesn’t destroy specimens with intense heat.

Finally, buy the microscope for your science lab from a reliable supplier.

You can browse the web to get the details of top and trustworthy dealers in your area. By buying microscope from a reliable supplier, you will definitely get the best value for your money and can have the microscope that will last for many years in your school science lab.

All About Cleaning and Maintaining Laboratory Glassware

Even the most carefully executed experiment can give erroneous results if dirty glassware is bought to use. If the glassware that is used for measuring liquids is contaminated with grease and other materials, it prevents the glass from being uniformly wetted. This in turn will affect the volume of liquid delivered and the amount of residue adhering to the walls of the container. Likewise, presence of impurities in glass labware can distort the meniscus and can prevent one from getting the correct results out of the science lab experiment.

Keeping the laboratory glassware physically neat and clean, free of grease, and bacteria is therefore of the utmost importance.

To keep your glass labware neat and clean, you must wash it immediately after use. Put glassware in water if you can not clean it immediately otherwise the residue will stick to the labware and it would get difficult to remove it.

For washing the glass labware, make use of soap, detergent, or cleaning powder. Try to use soap and cleaning powder without any abrasives as it can scratch the glass. However, for glassware that is too dirty, you can make use of cleaning powder with mild abrasive action to get good cleaning results. Chromic acid solution is quite effective in cleaning unduly clouded or dirty glassware. For scrubbing the glassware thoroughly, you must use a brush.

After cleaning, rinse the glassware with tap water. Allow the water to run into and over the glassware and then fill each piece with water. Fill test tubes, flasks, and other glassware with water and shake and empty them. Do this for at least 5-6 times to clean the glassware properly. For cleaning contaminated glassware, you will have to sterilize them too.

Washed labware must either be placed in a basket with their mouth downwards for allowing them to dry completely or they should be made to dry in an oven. You can also hang test tubes, flasks, and other labware on wooden pegs for drying them out. Stand dry cylinders, burets, and pipets on a towel for drying them properly.

Place clean glassware in a cabinet to protect it from dust. You can also make use of cotton, or cork, or can tape a piece of paper on the mouth of the glassware to prevent dirt and dust from entering the glassware. Keep washed, cleaned, and sterilised glassware pieces in special racks and at a distance to avoid any breakage.

With proper care and maintenance you can not only increase the life of your labware, but can also enhance your lab safety.
