Properly storing your microscope and keeping your microscope objectives clean are essential to extending the life of this valuable laboratory instrument.  Most microscopes purchased include a dust cover. Be sure to use it every time you store your microscope.

How to clean your optics:

Set up a tool kit with common cleaning items to keep near your microscopes. Clean your microscope objectives routinely, and be sure to wipe off excess immersion oil after each use.

Air puffer or squeeze bulb

Your cleaning tool kit should minimally contain an air puffer or squeeze bulb  to remove particles on the surface of the objectives.  Do not begin cleaning the surface of the objective if objects are present.  Small dust particles, dirt, or remaining specimens could be present and scratch the lens during wiping.

Camel Hair Brush

If particles remain on the objectives after using a puffer, a soft camel hair brush may be used.  Gently brush the objectives in a single motion.

When cleaning the lenses, avoid commercial facial tissue or Kimwipes® as these may contain silicone fillers that can damage the objective glass.

Use only lens paper on microscope objectives. To clean the objectives, place a sheet of lens paper over your objective.

Transfer Pipette

Apply a small amount of cleaning solution directly to your lens paper with a plastic transfer pipette.  Draw your wetted lens paper across the objective in a single continuous motion. Do not wipe back and forth with the lens paper.

The process may be repeated multiple times with new lens paper and solution until the objective lens is free of smudges. A solution of 50% Methanol may be used as a final cleaning agent to remove any remaining residue.  Never rub the lens and do not let the lens paper with cleaning solution touch the objective twice.  Clean in single, continuous swipes across the objective glass.

Lab Optic Cleaning Kit

Cole-Parmer offers a pre-built cleaning kit which contains an anti-static brush, probe, micro-fiber cleaning cloth, and a bottle of cleaning solution.

Inspect and service furnaces and heating equipment

Schedule annual maintenance from a qualified technician to ensure your furnace is clean and in good operating condition (and not a source of harmful carbon monoxide levels.)  Be certain your home has a carbon monoxide detector installed, and that it runs on fresh batteries.

For those who are HVAC service providers, Cole-Parmer offers a large selection of products for maintenance and inspection.  Carbon monoxide meters are great products for detecting safe CO levels.  To check for suitable electrical connections of furnaces and heating equipment, Cole-Parmer offers a wide selection of Clamp Meters.

Prior to the age of 53, most of Mayer’s scientific work was performed as a volunteer. Her first paid position was a part-time appointment at Argonne National Laboratory in suburban Chicago. Her role as senior researcher led her to develop the nuclear shell model of atomic nuclei, the work for which she was awarded the Nobel Prize.

The German-born Mayer came from a family of academics. She attended the University of Göttingen, the center of physics at the time. One of Mayer’s professors was Max Born, whose other students included Oppenheimer, Fermi, and von Neumann. After completing her doctoral dissertation, Mayer produced ten papers and a textbook, but could not garner a paid position. At the time of her award-winning discovery, researcher J.H.D. Jensen of Germany also arrived at the same structural conclusions and the two collaborated on the book Elementary Theory of Nuclear Shell Structure. Jensen, along with theoretician Eugene Wigner, shared the Nobel Prize for Physics with Goeppert-Mayer.

Eventually, Goeppert-Mayer was appointed professor at the University of California at San Diego. She died in San Diego in 1972. Goeppert-Mayer’s legacy as a female Nobel Laureate in Physics was preceded by Marie Curie (1903).

August is National Water Quality Month

In August the only water you may be thinking about is the nearest pool. Yet, as National Water Quality Month, the reality is not all of our water supply is equal in quality.  Did you know that each year in the US, by July 1, your local water supplier should provide your household with a water quality report?  Your water quality report (or drinking water quality report) summarizes the sources from which your water originates (such as rivers, lakes, reservoirs, etc) and contaminants detected, as well as includes compliance and educational information.

Because poor water quality not only impacts our personal health but also affects scientific research, Cole-Parmer offers effective water quality solutions.   As scientists and researchers, take a moment to consider the quality of water in your laboratory to ensure the integrity of your applications.  Consider a water purification system if your incoming water quality is poor.

As personal consumers, take a moment to learn about the quality of water in your community and in your household.  For more information regarding water quality, and tips on safe drinking water at home, visit the website for the United States Environmental Protection Agency (EPA):  http://water.epa.gov/

Cole- Parmer’s Canada office based in Montreal is hosting fellow United Kingdom colleague Lyssa Durham for the rest of the week as part of an office exchange program. Lyssa will be spending her first Canada Day in Montreal taking in the parade downtown.

“I’ve spent the last ten days here in Montreal. The office is fantastic and I’ve been getting to know the real Montreal, including their fine food and entertainment,” said Durham.

Another Canada office staff member will be spending the holiday camping in Mont-Tremblant. Cole-Parmer wishes all of our friends and colleagues north of the border a happy and celebratory Canada Day!

When using pH meters or ion meters to measure ion concentration in a solution, it may be beneficial to have multiple standard values to calibrate your ion selective electrode.  Typically, begin with a 1000 parts per million (ppm) standard and dilute this down to a smaller value such as 100 ppm and further to 10 ppm or even further if a lower concentration is required.

This helpful video illustrates a stepwise dilution of a 1000 ppm standard down to 1 ppm.  This procedure is quite common, however overlooking steps in the process, using poor technique, or lacking organization can lead to errors.  It is especially critical to stay organized.

We would love to hear from you.  Tell us your stories of mishaps when performing a serial dilution, or share tips to stay organized when performing this technique.

“At least twice a year, we gather our outdated respirators, refrigerators, and balances, among many other technologies, and ship them to Educational Assistance Ltd. (EAL),” explained Maureen Ranieri, Supply Chain Operations Manager. “EAL is a nonprofit organization that works with colleges across the country to convert this equipment into student scholarships.”

Specifically, EAL places inventory donations from manufacturers, distributors, and retailers with accredited US colleges and universities within their network. “We create an online shopping forum for these schools to pick and choose the items they need,” said John Saban, Development Director, EAL. “Each item is assigned a monetary value. Schools within the program commit to placing the value of the items they choose into a scholarship for students who need assistance. We conduct periodic audits to confirm that the monies are funneled into these scholarships.”

Began by a businessman who benefited from a GI Bill when he was a student, the EAL program has provided more than 10,000 scholarships since its inception in 1982. Current EAL Executive Director Claudia Freed was one of the first scholarship recipients through the program.

“Generally, we network with small to mid-size colleges that have limited budgets for equipment and supplies,” said Saban. Elmhurst College, Lee University, Judson College, and Robert Morris University are just some of the schools within their network.

EAL receives inventory donations of not only scientific equipment, but also computers, welding and maintenance supplies, power and hand tools, and commodities from a range of companies.

“Those items we cannot place are sold in the secondary market, typically in Europe, Asia, or South America,” said Saban. “We appreciate all donations and everything is utilized.”

 Ranieri added: “Our most recent shipment to EAL included 37 items for a total value of $93,000.”

Yet, the real value may be found in the futures of the graduating students who were able to complete their degrees because of the assistance they received.

H-B Instrument Enviro-Safe® Thermometer

Cole-Parmer is proud to present these new Earth-friendly “green” thermometers certified as 100% nontoxic, nonhazardous, and biodegradable.  These accurate and safe thermometers offer the same accuracy as mercury thermometers without the hazards.  They are ideal for use in laboratories, universities, food/beverage, environmental, wastewater, and many other general-purpose applications where the presence of mercury or other hazardous liquids is not desired. 

 All Enviro-Safe glass thermometers contain an environmentally friendly non-mercury liquid that is 100% certified as nontoxic, nonhazardous, and fully biodegradable. In case of breakage, the liquid can be cleaned up easily with soap and water.  These thermometers also have recyclable packaging, an antiroll fitting, individual serial numbers, and a statement of accuracy.

So, what’s so bad about mercury thermometers, anyway?

Mercury thermometers are harmful to both the environment and your personal health.  In fact, Mercury is toxic to humans and wildlife.  If a mercury thermometer breaks and is not properly disposed of, tiny droplets of mercury can evaporate within the environment over time.  When mercury vapor enters the bloodstream through inhalation, brain damage, spinal cord, kidney, and liver damage may occur in time.

Additionally, improperly disposing of mercury from thermometers can contaminate lakes and streams.  Mercury may accumulate in the bodies of fish and other wildlife and, through natural processes, converts this mercury into methyl mercury, which is harmful to humans when consumed.

Antiseptic Hand Cleanser

According to the Centers for Disease Control and Prevention (CDC), flu activity is picking up. In most years, flu activity peaks in January or February but can vary from year to year.  With the winter months approaching, you can take precautions to protect yourself from the virus.

It is extremely important when working with electrical equipment to take appropriate precautionary measures such as de-energizing electrical equipment and, of course, wearing personal protective equipment (PPE).  Arc Flash PPE materials are tested for their arc rating, which indicates the maximum incident energy resistance of that material.  Arc rating is typically expressed as small calories of heat energy per square centimeter (cal/cm2).  Tests to determine arc rating are available in ASTM F1506-10 Standard Performance Specification for Flame Resistant Textile Materials for Wearing Apparel for Use by Electrical Workers Exposed to Momentary Electric Arc and Related Thermal Hazards.

While PPE is important, the downside is that it provides protection after an arc flash incident has already occurred, and therefore should be viewed as the last line of protection. Reducing the frequency and severity of incidents should be the first option and can be achieved through a complete arc flash hazard assessment, along with implementing technology such as high resistance grounding (proven to reduce the frequency and severity of incidents).

In addition to appropriate PPE, consider working outside the hazard zone.  One product offered by Cole-Parmer that allows taking readings outside the hazard area is the Fluke 233 Remote Display Multimeter.

Fluke 233 Remote Display Multimeter

The 233 is a rugged digital multimeter (DMM) that can be used just like any other DMM in the field. Yet, it also offers the ability to safely take readings while energizing and de-energizing equipment. How many times have you had to place a meter in a precarious— and possibly unsafe position—in order to observe the readout? The wireless technology greatly reduces these risks.

A common practice in the electrical field is for someone to hold the meter as the technician reaches inside the control panel or switchgear to place the test leads for the measurement. This “meter reader” then is exposed to virtually the same shock and arc-flash hazards as the individual placing the test leads. With the 233’s detachable head, this “meter reader” can now stand safely outside of the Flash Protection Boundary while recording readings. Another issue― the inconvenience of taking readings while dressed out for Hazard Risk CAT III or CAT IV―also finds a remedy By enabling the person observing the meter reading to stand outside of the boundaries stated above, protective clothing requirements can most likely be reduced to a lower Hazard Risk Category..

Cole-Parmer cares about safety and offers a wide selection of safety apparel and electrical equipment to provide protection against arc flashes.
