KNF’s Laboratory Symposium Offered an Evening of Exploration and Learning

Last week, KNF Neuberger Inc. hosted a Laboratory Pumps and Applications Symposium in collaboration with the Trenton Section of American Chemical Society (ACS). The event, a first of its kind, attracted attendees from local academia and industry.

Beginning in the early evening, the Lab Symposium kicked-off with a mixer featuring beverages and hors d’oeuvres. Attendees became better acquainted with each other, and more familiar with KNF laboratory equipment which was on display throughout the room. Soon after, guests were invited to a guided tour of KNF’s 50,000 square foot manufacturing facility. The tour, led by KNF Director of Sales and Marketing, Eric Pepe, allowed symposium guests to view important aspects of KNF’s pump production area including: assembly and testing stations, high-tech machining equipment, and state-of-the art inventory management systems.

Next, attendees were invited to help themselves to a complimentary hot buffet, featuring local Italian fare. Guests and staff carefully balanced plates, as they made way to their seats for the Laboratory Pumps and Applications presentation, delivered by KNF Laboratory Products Manager, and applications specialist, Roland Anderson (pictured right). The presentation featured a review of pump technologies, their pros/cons, and the benefits of their usage in several typical lab applications.

The evening was capped off with desserts and coffee, as well as a door prize drawing. Congratulations to the prize winners, and thank you to all who helped make this initial KNF Laboratory Pumps and Applications Symposium a success!

If you would like to schedule a similar KNF lunch-and-learn symposium with KNF, at your facility, please contact a laboratory applications specialist.

 

 

Adding Convenience to Field Filtration, Thanks to the New Mini-LABOPORT® Pump

Field Filtration Pump

Filtration of field water samples is not that easy. In discussions with customers, they’ve mentioned three alternatives that are available to accomplish the task, none of which are ideal:

  • Use a manual vacuum pump. However, manual pumps can be weak and therefore very slow. And, they can wear you out if you have a lot of samples or ones with moderate-to-heavy particulates.
  • Use a generator to power a standard lab bench vacuum pump. This option requires transporting the heavy generator and gasoline to the field water site.
  • Transport samples back to the lab. Transportation requires the extra step of packaging the unfiltered samples, and means a delay in getting results and possible degradation of the sample depending on what is being collected and/or tested.

KNF engineers decided that a fourth option would be useful to field scientists, so they developed the new lightweight 12 volt mini-LABOPORT pump, model PJ26078-811. Designed specifically for in-the-field use where vehicle access is possible, it combines the robust operation of the traditional KNF LABOPORT pump with the ability to be powered via 12V DC car outlet. Therefore, field scientists can now rely on a lightweight oil-free vacuum source in environments where weight, portability, space, and timeliness often factor into operation.

KNF LABOPORT 12V Field Filtration PumpEquipped with a three-meter long, coiled power cord fitted with a 12 volt car outlet adaptor cord and two 1/4” hose barbs for vacuum inlet and outlet, the new 12 volt mini-LABOPORT pump is ideally suited for filtration and gas sampling in the field. Its combination of compact convenience and reliable performance allow it to meet the needs of environmental companies, water treatment plants, field researchers, and anyone in need of a convenient vacuum source in remote locations.

Employing a compact, low-maintenance design, the pump is driven by a sturdy motor and features chemically-resistant construction. Providing up to 11 L/min flow at atmosphere, it offers 75 Torr (100 mbar) end vacuum.

ACS Fall: Thanks for a Great Show

The KNF team, after a successful ACS Fall.

The KNF team, after a successful ACS Fall.

The 248th ACS National Meeting & Exposition has officially come and gone. From the attendees to the ACS show team, as well as our KNF staff, thanks to the many hard working moving parts that came together to make this such a successful show. We enjoyed talking to a lot of you about your laboratory vacuum and liquid pump needs and in particular about the new RC 900 Rotary Evaporator.

We’re not done just yet though; we have more winners to announce! Selected from Monday’s visitors to our booth, Jane Aldrich, from The University of Kansas, won herself a $100 Visa Gift Card. And on Tuesday, David Myers, of Bard College at Simon’s Rock, was awarded a Visa Card worth $100 as well.

And at long last, our Grand Prize Winner is… Kevin Woller, of AbbVie. Congrats! You’ve won a $250 Visa Gift Card; thanks for coming by our booth and learning about our latest products.

Also, be on the lookout for forthcoming information on our website and blog about the new 12 volt Mini LABOPORT® field filtration pump. This new pump provides lightweight and portable vacuum filtration powered by a simple 12 volt car receptacle.

Oil-free Pumps Deliver Environmental, Cost Benefits in the Lab

With all companies increasingly focused on sustainability, selecting products – including those for the lab – that reduce or eliminate waste and save energy are becoming a top priority. While many labs have traditionally relied on oil-lubricated vacuum pumps, oil-free alternatives have become prevalent, in part, because they are better suited to comply with corporate guidelines for reducing carbon footprint. The  question, however, is what other advantages do these pumps provide and how do you select the best one for your application?

In most instances, the price of an oil-free pump, sometimes referred to as a dry pump, is higher than the oil-lubricated alternative. However, when you consider the process savings, lower user costs, and environmental benefits, oil-free pumps, such as the KNF LABOPORT® shown in figure 1, more than pay for themselves over the long life of the pump. Let’s review two key advantages in a bit more detail:

Footprint:
This applies to both the carbon version and the actual space in the lab. Eliminating oil means there is no risk for  contamination, and no  need for oil changes and subsequent expensive, hazardous material disposal. Also, they do not emit fumes that   contaminate the air. Oil-free pumps also are more compact, requiring less room on the bench, helping reduce the overall size of the lab in  some cases.

Operating Costs:
Considering the long life of pumps in the lab, operating costs should be a major consideration, especially in relation to  the actual purchase price. Less energy is required to run the oil-free pump, creating lower electricity bills for a lab. As oil-free pumps can be built to be corrosion-resistant, and again, since there is no need for oil changes and associated expenses, maintenance costs are lower, as  well.

Selecting the Best Pump for Your Application:
Now, there are many different oil-free vacuum pumps to choose from. Scientists and other lab professionals are not always sure which one is best for their application. A good first step is to select the manufacturer. Look for a manufacturer that understands the application and has the benefit of experience. This will help ensure the proper pump is selected for your individual lab requirements.

Selecting the proper vacuum level is also important. Many times, especially with older oil-lubricated pumps, the capacity and vacuum levels exceed what is truly necessary. Matching the vacuum to the application will result in more efficient operation and cost savings.

Also consider service. Of course, oil-free pumps are highly reliable, as many models can go 10,000+ hours without needing service. Some pumps, such as those designed and manufactured by KNF, can have a diaphragm replaced on site in a half hour with just a screwdriver.   There’s no hazardous materials handling and drainage, nor is a specialized service professional required to perform the work. Think of it as simply changing the filter in your air conditioning unit.
