Welcome to Greener Lab Solutions™
Is your lab looking to improve your research laboratory processes while reducing its impact on the environment? Then take the green chemistry and green laboratory challenge and see the newest and greenest products available for science researchers today. The companies showcasing their products focus on designing chemicals, reagents, products and instruments less hazardous to the environment, and designing chemical synthesis and other processes to produce your supplies and reagents in a more energy efficient way. Interact with companies who are looking for ways to use renewable resources to produce the products you use in the lab. In addition these suppliers strive for laboratory methods and supplies that are:
* Less toxic to living organisms and entire ecosystems
* Not bio accumulative in organisms or the environment
* Are inherently safer with respect to handling and use
The 12 principles of green chemistry are:
Prevent waste: Design chemical syntheses to prevent waste, leaving no waste to treat or clean up.
Design safer chemicals and products: Design chemical products to be fully effective, yet have little or no toxicity.
Design less hazardous chemical syntheses: Design syntheses to use and generate substances with little or no toxicity to humans and the environment.
Use renewable feedstock: Use raw materials and feedstock that are renewable rather than depleting. Renewable feedstock are often made from agricultural products or are the wastes of other processes; depleting feedstock are made from fossil fuels (petroleum, natural gas, or coal) or are mined.
Use catalysts, not stoichiometric reagents: Minimize waste by using catalytic reactions. Catalysts are used in small amounts and can carry out a single reaction many times. They are preferable to stoichiometric reagents, which are used in excess and work only once.
Avoid chemical derivatives: Avoid using blocking or protecting groups or any temporary modifications if possible. Derivatives use additional reagents and generate waste.
Maximize atom economy: Design syntheses so that the final product contains the maximum proportion of the starting materials. There should be few, if any, wasted atoms.
Use safer solvents and reaction conditions: Avoid using solvents, separation agents, or other auxiliary chemicals. If these chemicals are necessary, use innocuous chemicals.
Increase energy efficiency: Run chemical reactions at ambient temperature and pressure whenever possible.
Design chemicals and products to degrade after use: Design chemical products to break down to innocuous substances after use so that they do not accumulate in the environment.
Analyze in real time to prevent pollution: Include in-process real-time monitoring and control during syntheses to minimize or eliminate the formation of byproducts.
Minimize the potential for accidents: Design chemicals and their forms (solid, liquid, or gas) to minimize the potential for chemical accidents including explosions, fires, and releases to the environment.
How to Get Help With College Assignments
If you're a college student, you'll be familiar with the influx of homework assignments. Luckily, there are many services to help you navigate this process.
One of the most common ways is to enlist the aid of a professional. This can be in the form of a tutor or a writing service. It's not uncommon for students to get caught up in extracurricular activities, which make it hard to study.
Another option is to use the help of an online service. They can perform the task in a timely fashion, without causing you any plagiarism problems. However, it's a good idea to have a calculator on hand.
When it comes to writing your college papers, it's important to do them properly. Your college professors are looking for high quality work, so you'll need to take the time to get it right. Using a college assignment service can be a big advantage when it comes to achieving the highest possible grade.
Although there are many online service providers, it's important to find a trustworthy source. The best way to ensure you don't end up scammed is to go with a reputable writing service.
To snag the highest possible score, you'll need to get help with college assignments. For instance, if you're getting ready to submit your paper on the same day as an exam, you'll want to start on it immediately.
Getting the best grades is the main objective, but you don't have to spend all your free time studying. Make a study schedule and set aside some time to get the most out of your studies.
