Paying it Forward

As we often remind folks, scales and weighing related solutions are all around us. Today we wanted to take a look at an application that you might not think about when it comes to weight.

Paying it forward should accomplish things that the other person cannot accomplish on their own. From this, the practice of helping one another can spread exponentially throughout society, at a ratio of three to one, creating a social movement with an impact of making the world a better place.

The New England Organ Bank regularly facilitates the ultimate “pay it forward,” using one lost life to save or improve another.

All organ and tissue donations begin with a weight. Once consent for donation has been obtained through either the donor’s DMV records or from next of kin, the donor’s weight must be recorded. This is one of the first qualifiers to move on to the next stage: recovery. Once a confirmed weight passes as acceptable, tissue samples undergo rigorous testing. Serology tests are run on the donor to ensure the samples are safe and disease-free. Cultures are also taken on every tissue recovered.

Prior to 2009, an accurate means of measuring weight was missing, potentially skewing acceptable donations from moving forward to the recovery phase. Donor weight was estimated based on medical records and the family’s best estimate—which was not always accurate. New England Organ Bank rightly errs on the side of caution whenever something is in question, and estimating weight meant perfectly safe tissue could be deemed unsafe for transplants. If a donor’s weight was on the border of acceptance, it would not advance to the recovery phase. A more precise means of recording donor weight was needed to ensure no acceptable tissue would be lost. The organ bank needed a custom floor scale exhibiting accurate weighments and durability, while adhering to strict sanitary standards.

In addition to accuracy, the organ bank also required a scale in the recovery area that could withstand equally important washdown requirements. Avoiding contamination is essential in the transplant process—a factor which requires special scale considerations. With the installation of the custom washdown-ready Rice Lake floor scale, the donor’s weight is now precisely recorded and converted into kilograms, which is the industry standard unit of measure. This weight is used to calculate the total amount of blood and plasma a donor can receive without compromising the tissue sample; too much fluid given results in dilution, making it unfit for transplantation.

“The scale needs to provide an accurate weight of the donor,” Kristina explains. “This is very important because if the scale is off, or the weight is estimated, the calculation for fluid levels won’t be accurate. We are very happy with Rice Lake’s floor scale which gives us readings down to a tenth of a gram.”

Another wonderful example of how Rice Lake scales work accurately and provide a high quality solution for many industries throughout the world. Whether it’s wash down with water or industrial warehouse type scales; pounds or grams, the odds are pretty good that you can find a Rice Lake scale, either standard or custom built that will meet your requirements.

Rice Lake 920i Flexweigh At Work…

Pasta is a finicky food. Most people think of it in its fully cooked state—soft, succulent and durable enough to harmlessly toss against a wall to gauge its eat-readiness. However, the pasta manufacturing process reveals its true identity: a rigid, break-happy material demanding ultimate precision and care. When Claude Smith became plant manager of Pasta Montana in 2010, he immediately noticed areas that needed improvement. Bulk containers weighing between 500-1000 pounds were being manually filled and adjusted to reach specified targets. “It was a very time-consuming and inefficient process,” Claude explains. “We set the empty container on a floor scale, weighed it, and then scooped product in and out until we got the right weight. People were using their best guess to predict the overshoot or undershoot on the scale.”

Furthermore, operators were confined to an area near the weight display. “Someone always had to keep an eye on the readout,” Claude continues. “We spent a lot of time adjusting the weight and had to use two people on the job because of the inefficiencies.” Pasta Montana manufactures pasta 24 hours per day / 7 days per week, and at least one of those days was devoted to this bulk filling process. Making dry pasta is a continuous process. The raw material, semolina, is mixed and extruded through a set of dies to determine shape based on customer needs. After its shape is formed, the pasta mix enters a dryer for approximately four hours. It then runs through a cooler to avoid condensation. Once out of the cooler, the pasta travels through a few elevators and on to the next line, where a tote, bag or box is filled and packaged. This process runs on a loop, around the clock. “We needed the tote filling process to be continuous,” Claude explains. “If there’s a shutdown, it affects everything. Pasta dryers require a lot of humidity to dry the pasta. It seems counter-intuitive, but the humidity comes from the product. So if you’re not continuously putting fresh product in the dryer and taking dry product out, the process stops. It’s difficult to maintain good quality product because you’re eating away your humidity and not replenishing it in the form of product that’s been freshly extruded. If a line stops, we have product ready to exit the dryer and product ready to enter the dryer and each is now suspect in quality. In the past, this happened when we had issues filling totes, the operator fell behind, or a button wasn’t pressed at the right time.” After a thorough review of the process, a Rice Lake 920i FlexWeigh System 101 was selected to control the bulk packaging process.

The 920i FlexWeigh 101 system features a simple, rock-solid program that’s as easy as 1-2-3:
1. Empty container is placed on the scale
2. Container is automatically filled to a preset weight
3. Filled container is replaced with an empty container

With 920i FlexWeigh 101s in place, line stoppages no longer occur. The proverbial bottleneck which once existed in packaging has now spun its way back to processing. Increased packaging capacity has created a ravenous demand for more product. “I knew of Rice Lake by reputation,” Claude remembers, “but never had the chance to work with the products until this project. In the food industry, everything is very cut and dry. Either something works or it doesn’t; there aren’t very many shades of gray. The highest compliment I can give Rice Lake is that their stuff just works. I’m very happy with the results. One person can now run that packaging line without worrying about keeping an eye on the scale’s digital readout or scooping product in and out. They are free to allow the system to fill, build a few totes ahead of schedule, and come back when it’s done.” This was just the beginning. Click here to read the entire article.

New Requirements for Laboratory Balances?

The U.S. Pharmacopeial Convention (USP) is a scientific nonprofit organization that sets globally-recognized standards for quality of medicines, food ingredients and dietary supplements developed and manufactured for human consumption. The USP’s guidelines recently underwent major revisions, and in December 2013, updates to Chapter 41 and 1251, which have an impact on weighing technology went into effect.

Chapter 41 focuses on the “requirement for balances used to weigh analytes for quantitative measures.” Balance repeatability and accuracy was once an area in which there was once much ambiguity, and the updates attempt to better define the parameters to be used when determining the appropriate minimum weight and operating range. The updates to Chapter 41 include increasing the number of balance tests from one to two, changing expansion factor from 3 to 2 and increasing the limit of repeatability test from ≤ 0.1% to ≤ 0.10% to reduce errors caused by rounding. Additionally, Chapter 41 addresses calibration weights for the first time, indicating that test weights should be between 5% and 100% of balance capacity.

Chapter 1251 has undergone major revisions focusing on balance qualification and operation. Among the new additions is a clear definition of minimum weight, which refers to the sample weight, and not tare or gross weight. Chapter 1251 also defines protocol for balance testing frequency, in order to ensure necessary testing is conducted and unnecessary testing can be eliminated, helping to improve laboratory efficiency. For example, a daily balance check, which is typical in many laboratories, is not actually a requirement. Instead, the type and frequency of balance checks should be determined by the risk and process tolerance of the application. Performing the right tests at the right intervals will ensure quality results and can potentially save time and money by eliminating unnecessary testing!

While the criteria listed in Chapter 41 is enforceable, Chapter 1251 includes recommendations for optimal results.

Defining guidelines and requirements for accurate and precise weighing from the outset will help assure accuracy during every phase of a project. OHAUS portfolio includes multiple balances, including the Explorer and Adventurer Pro, that conform to these guidelines and can assure that all weight determination in pharmaceutical compounding applications meet the criteria set forth by the USP.

Quick Note of Thanks

The crawlspace of your home is often something you never think about, yet it’s really an integral part of maintaining your house (especially for those of us in the southern United States).

Damp and humid crawl spaces create conditions conducive to mold/mildew growth, deterioration of wood structural members, wood destroying insect infestation, buckling of hardwood flooring, and significantly decreased indoor air quality.

So with that being said, we just wanted to give a quick word of appreciation to Crawlspace Tech for giving us a little advice and feedback recently.  Based on their experience as home inspectors, they are able to design and implement a strategy for vastly improving the environment under a house, and can often do this at a better price than those “specialists”.  They also can design a solution for you to install yourself for a small fee.

They approach each situation as a building inspector and clearly define the line between necessary and excessive.  Once again, just wanted to say thanks and we appreciate your honest feedback and courtesy.

New Detecto PS30 Compact Digital Portion Scale

The NSF-certified stainless steel PS30 scale is versatile enough for use in food service portioning, industrial, shipping, plant processing, and general purpose weighing. DETECTO’s new model PS30 compact countertop portion scale boasts a hefty 30-lb/15-kg capacity. The digital scale weighs in pounds, ounces, both pounds and ounces, pounds and ounces with fractional 1/8th ounce, and kilograms. These selectable units may be preset to display only those desired by the user.

The scale’s IP65 washdown rating signifies that the durable PS30 is protected against dust and low-pressure water. This rating is perfectly suited for a commercial kitchen where heavy wash-down cleaning can be a daily necessity. The roomy stainless steel lift-off platform may be easily removed for frequent washing in food and chemical applications where a clean, sanitary surface is required.

The PS30 features five large 1-in (26-mm) high digits (plus fractional ounces) and a brilliant backlit blue LCD display that may be toggled on or off. Operation of the scale is simple with only four convenient buttons: Hold, Tare/Backlight, Units, and On/Off. Auto-zero circuitry ensures that zero is established on the power-up routine and is maintained throughout operation.

A low-battery indicator and automatic shut-off with adjustable timing conserve battery power and extend the life of the four AA batteries (not included). By adding the optional batteries, the PS30 has up to 110 hours of continuous use with the backlight off for all mobile weighing tasks such as farmers markets and roadside stands. An AC adapter is also provided with the scale for more fixed portioning applications.

The 30-lb capacity wasn’t achieved by trading counter space as the PS30 has a slim, compact design that leaves plenty of work space in even the tightest of countertops while still maintaining an ample 9.5-in W x 7.3-in D (24-cm W x 19-cm D) platter. Despite the higher capacity, the scale is still sensitive enough to weigh in 0.1-oz (2-g) increments, which accommodates the necessity of a perfectly balanced recipe or the precision of measuring corn, wheat or soybeans in an agricultural application.
