Celebrate the drive, innovation and passion of America’s small businesses


SPEX CertiPrep is a small business dedicated to not only meeting, but also exceeding your expectations through unparalleled value-added service. Our commitment to quality is the key element to the success of our business. Celebrate the Drive, Innovation and Passion of America’s Small Businesses like SPEX CertiPrep.

Why Support Small Business?1
  • When we support small business, jobs are created and local communities preserve their unique culture.
  • Because this country’s 28 million small businesses create nearly two out of three jobs in our economy, we cannot resolve ourselves to create jobs and spur economic growth in America without discussing ways to support our entrepreneurs.
  • Small businesses are the backbone of our economy and the cornerstones of our nation’s promise.



SPEX CertiPrep products are proudly made in the United States. We are based in Metuchen, New Jersey and have been servicing the scientific community since 1954.
We are committed to providing products that meet your required specifications by providing superior Certified Reference Materials for Analytical Spectroscopy and Chromatography. Made for Chemists by Chemists®

Why Buy American?2
  •  JobsThe most common reason shoppers buy American made products is to help save or create jobs in the United States.
  • Lower Carbon Footprint. Products made overseas have a higher carbon footprint than U.S. made goods. Goods made in China or India have to be shipped all the way across the ocean to reach American stores, burning fossil fuel and spewing out greenhouse gases with every mile they travel.
  • Less Pollution. One reason it’s cheaper to make goods in developing countries is that many of them have few or no regulations to protect the health of the air and water. Many factories overseas that produce goods for export to the United States also produce large amounts of hazardous chemicals that pollute the air, water, and soil.
  • A Stronger Economy. Buying American-made goods doesn’t just support the workers who make those goods. Its benefits also ripple out through the entire economy. When American factories prosper, they hire American construction firms to expand their buildings, American accounting firms to handle their money, and American energy suppliers to provide them with power.

SPEX CertiPrep Celebrates Earth Day

Earth Day.jpgIn April, we celebrate the earth by observing a very important day – Earth Day!

Never heard of it? Well, Earth Day has been around for more than 30 years. It was started by Gaylord Nelson, a 53-year-old Wisconsin senator, as a way of bringing attention to how people’s actions were endangering the planet.

Nearly 20 million Americans participated in the first Earth Day on April 22, 1970 by picking up litter, collecting recyclables, and holding “teach-ins” to talk about the environment. This widespread concern by citizens about what was happening to the Earth inspired the U.S. Congress to pass the Clean Air Act (www.epa.gov/clean-air-act-overview) in the early 1970s.

Logo Concept 4-01

This year SPEX CertiPrep celebrates Earth Day with the unveiling of our SPEX Community Garden. We all know that we need to eat fresh fruits and vegetables for a healthy diet. Some foods we will be growing include spinach, cucumbers, tomatoes, pumpkins, beets, and strawberries (yummy). Not only will our garden help us eat better, but it will help us to reduce stress, allow us to be social with our fellow colleagues, teach us how to garden, and we will be giving back to our community by donating part of our harvest to the local food pantries.

In addition to our fruits and vegetables garden, we are planting wildflowers along the right hand side of our building in an effort to bring back the bees.

Did you know that the bee population everywhere has been declining at an alarming rate¹? 1 in 3 bites of food we eat is made possible by the bees and other pollinators². 44% of bee colonies in the U.S. collapsed in 2016³. More than two thirds of the world’s crop species rely on pollinators†.

What will you do to celebrate Earth Day?

The Clean 15

The 15 fruits and vegetables listed in our infographic below make up the “Clean 15” list because they are least likely to be contaminated with pesticide residues.

Pesticide Residue and the Dirty Dozen

The ‘Dirty Dozen’ published by the Environmental Working Group (EWG) is a list of produce containing the highest pesticide residue levels. In 9 years, apples have appeared in the top three most contaminated items eight times and has been the most contaminated item five times (followed by peaches and celery).
