The month of March brings the Luck of the Irish – Shamrocks, St. Patti’s Day, Leprechauns… Our first special-themed Henry for 2020 is Leprechaun Henry. He’s greener than a Shamrock Shake, and he’s in very limited quantities. This St. Patti’s Day plush won’t be bringing any pots o’ gold, but he’s sure to bring you luck all year long. He is expected to be out of stock BEFORE March 17th – so get yours before he disappears for good (no restocks on this one). Customers have to spend $99 or more, and request Leprechaun Henry with their orders. If ordering online, requests for Leprechaun Henry (and any other giveaway) can be placed in the Shipping Instructions field during the Checkout process.
Extraneous tissue, commonly known as floaters, in the lab, will never be completely eradicated from our testing practices, but we can take steps to understand where it comes from, and how we can prevent it.
Main sources of floaters include, the grossing bench, the embedding stations, and the microtomy stations. At each station, cleaning is an important factor in prevention of floaters. If forceps aren’t cleaned between each and every specimen, you can get fragments of tissue that carry from one specimen to the next. Similarly, if forceps are not cleaned between cassettes, tissue can get carried from one block to the next. Also be mindful of the wells the forceps are stored in and ensure regular cleaning of these occurs. At the microtomy station, ribbon fragments can get picked up if you’re not cleaning the water bath surface between blocks. Cleaning! Cleaning! Cleaning! It really is super important.
Make sure to use common sense practices in your lab, such as not putting your fingers in the water bath or touching the slide in parts other than the sides. Wearing gloves can also reduce the likelihood of your own cells becoming extraneous tissue.

Worldwide, more than 70,000 cases of the new coronavirus have been reported and more than 1,700 people — the vast majority of them in mainland China — have died of COVID-19.
The Diamond Princess Cruise Ship has been under Japan-ordered quarantine since Feb. 5, after a passenger who had disembarked earlier tested positive for the virus in Hong Kong. Fourteen U.S. passengers were evacuated from the cruise ship in Japan and flown to military bases in California and Texas have tested positive for the new coronavirus, U.S. officials confirm. An additional 44 Americans from the Diamond Princess ship who tested positive for coronavirus will stay in Japan while they recover. Some have been hospitalized, but not all who are infected are sick.
Doctors in five U.S. cities will begin testing patients with flu-like symptoms for the new coronavirus, the Centers for Disease Control and Prevention said Friday.
The coronavirus test will only be given to patients who test negative for the flu. So far, the testing protocol will be implemented in Chicago, Los Angeles, New York, San Francisco and Seattle, though more cities will be added. Dr. Nancy Messonnier, director of the CDC’s National Center for Immunization and Respiratory Diseases said the increased testing is part of an effort to determine whether the virus is spreading in communities across the U.S. “The results would be an early warning signal to trigger a change in our response strategy,” she said.
We have experienced an enormous increase in demand for masks, disinfecting wipes, hand sanitizer, gowns and many other infection control products as health facilities and laboratories attempt to prepare for further impact of this virus. Currently, masks are the primary product impacted. We are not taking orders for masks unless product is readily available. Your orders remain non-cancellable and non-returnable for all impacted product categories. We are working with our manufacturing partners to secure product for you.
Product categories include: N95 masks, regular earloop masks, disinfecting wipes, hand sanitizer, thermometers, isolation gowns, gloves and other infection control categories.
We will keep you posted on changes in product availability.

CarboPrep Plus (CPP) may be used to clean EPA 8082 extracts for Aroclor quantitation, provided caution is exercised in choosing the quant peaks, setting up the possibility of processing a combined pesticide/PCB extract without the sulfuric acid clean up step.
Why clean the PCBs extracts at all? If pesticide extracts are run on the same instrument regular maintenance would be required to meet the stringent inlet inertness requirements for endrin and DDT. PCB methods typically do not have the same stringent requirements, however samples typically have high concentrations of non-volatile matrix compounds that build up in the inlet effecting chromatography, which effects quantitation.
An effective cleanup is also important since chromatographic interferences make it difficult to perform Aroclor pattern identifications. Other challenges include weathering which can significantly change the Aroclor pattern combined with different Aroclor mixtures.

• Maximum Contaminant Removal
• Less Instrument Downtime
• Higher Sample Throughput
Keep your organochlorine pesticide GCs up and running by protecting them against matrix components with superior sample cleanup. Resprep CarboPrep Plus SPE cartridges surpass traditional Florisil products in cleanup power for sample matrix compounds that cause active sites in GC inlets and columns, degrading pesticides and interrupting work due to failed calibration checks. For CarboPrep Plus cartridges, Restek uses a proprietary treatment to create an exceptionally clean carbon that exhibits consistent selectivity. The end result is a reliable sample preparation product that does not contribute interfering background signal and does not need to be evaluated lot to lot to see if elution volumes need to be adjusted. In addition, CarboPrep Plus cartridges are designed to use the same equipment, solvents, and solvent volumes as a traditional Florisil cleanup procedure, minimizing the impact of switching on sample prep labs while maximizing the performance benefit to analytical labs.
