SPEX CertiPrep is putting BLUE in Your Lab

SPEX CertiPrep Proudly Supports Prostate Cancer Research and Awareness.
September is Prostate Cancer Awareness month. Prostate cancer is the most common type of cancer among men in the United States, other than skin cancer. Prostate cancer affects more than 3 million men every year, worldwide. At SPEX CertiPrep, we support the hope that the greater knowledge will lead to earlier detection for higher long-term survival rates.
Awareness needs to be ongoing so we are putting blue in your lab!
During the month of September, all web orders will receive a FREE blue vial rack to brighten up your bench space and be a reminder to take the steps to plan and detect prostate cancer in its early stages and encourage others to do the same.

Did you know?

  • About 1 man in 9 will be diagnosed with prostate cancer during his lifetime.
  • Prostate cancer can be a serious disease, but most men diagnosed with prostate cancer do not die from it. In fact, more than 2.9 million men in the United States who have been diagnosed with prostate cancer at some point are still alive today.
  • Other than skin cancer, prostate cancer is the most common cancer in American men. The American Cancer Society’s estimates for prostate cancer in the United States for 2019 are:
    • About 174,650 new cases of prostate cancer
    • About 31,620 deaths from prostate cancer

To celebrate Valentine’s Day, during the week of February, 10th, we will donate 15% of all web orders to Ocean Conservancy.

Ocean Conservancy educates and empowers citizens to take action on behalf of the ocean. From the Arctic to the Gulf of Mexico to the halls of Congress, Ocean Conservancy brings people together to find solutions for our water planet. Informed by science, our work guides policy and engages people in protecting the ocean and its wildlife for future generations.

Check out the Ocean Conservancy Wildlife Fact Sheets for information about a variety of wildlife that depend on our health oceans.

SPEX CertiPrep Technical Note

SPEX CertiPrep Technical Note:

A Technical Guide to Standards, Calibration Curves and Dilutions for the Laboratory User




Certified standards or certified reference materials (CRMs) are materials produced by standards providers which have one or more certified values with uncertainty established using validated methods and are accompanied by a certificate. The uncertainty characterizes the range of the dispersion of values that occur through the determinate variation of all of the components which are part of the process for creating the standard.

CRMs have a number of uses including: validation of methods, standardization or calibration of instruments or materials, and for use in quality control and assurance procedures. A calibration procedure establishes the relationship between a concentration of an analyte and the instrumental or procedural response to that analyte.

A calibration curve is the plotting of multiple points within a dynamic range to establish the analyte response within a system during the collection of data points. One element of the correct interpretation of data from instrumental systems is the effect of a sample matrix upon an instrumental analytical response. The matrix effect can be responsible for either analyte suppression or enhancement. In analysis where matrix can influence the response of an analyte, it is common to match the matrix of analytical standards or reference materials to the matrix of the target sample to compensate for matrix effects.

Go Pink for Breast Cancer Awareness

Breast cancer awareness is an effort to raise awareness and reduce the stigma of breast cancer through education on symptoms and treatment. At SPEX CertiPrep, we support the hope that greater knowledge will lead to earlier detection of breast cancer, which is associated with higher long-term survival rates, and that money raised for breast cancer will produce a reliable, permanent cure.

Awareness needs to be ongoing so we are putting pink in your lab.

All web orders in the month of October will receive a free pink vial rack. The pink vial rack will brighten up your bench space and be a reminder to take the steps to plan and detect breast cancer in its early stages and encourage others to do the same.

Did you know?

  • About 1 in 8 U.S. women (about 12.4%) will develop invasive breast cancer over the course of her lifetime
  • In 2019, an estimated 268,600 new cases of invasive breast cancer are expected to be diagnosed in women in the U.S., along with 62,930 new cases of non-invasive (in situ) breast cancer
  • For women in the U.S., breast cancer death rates are higher than those for any other cancer, besides lung cancer
  • About 85% of breast cancers occur in women who have no family history of breast cancer. These occur due to genetic mutations that happen as a result of the aging process and life in general, rather than inherited mutations

In part 2, Patricia Atkins discusses the next steps in her Cannabis-related research and what excites her most in the field. You can view part 2 here.

Do You Know What Goes Into Your Favorite Fireworks Display? Chemistry!

An exploding firework is essentially a number of chemical reactions happening simultaneously or in rapid sequence. When you add some heat, you provide enough activation energy (the energy that kick-starts a chemical reaction) to make solid chemical compounds packed inside the firework combust (burn) with oxygen in the air and convert themselves into other chemicals, releasing smoke and exhaust gases such as carbon dioxide, carbon monoxide, and nitrogen in the process.

Here’s a New Episode of SPEX Speaks Science
The Chemistry of Hot Sauce

Abstract: The rise of popularity of spicy products and hot sauce has skyrocketed over the last decade. Hot sauces have gone from a few well known brands to a cottage boutique market and an international obsession. In this podcast, we will look at the chemistry of hot peppers and hot sauces and how these products affect the body.

Episode 1: History of Pesticides

Abstract: Pesticides are now a daily part of our world, from the anti-bacterial soaps we use to the commercial pesticides that are applied to our food. Despite the fact that the chemical age of pesticides has just skyrocketed in the last decade, the use of pesticides has been thousands of years in development.

Join SPEX CertiPrep as we look at the history of pesticides, the development of modern pesticides and how those pesticides are applied and regulated. We will examine the genesis of the chemical pesticide movement and explore the regulation, approval and application of modern pesticides and take a look into the future of pesticide management.
