New Kids on the Block

TIPS FROM THE SERVICE BENCH

Phillips and Allen have dominated machine, sheet metal and cap screws for a long time. They are popular, easy to use and easily recognizable. But Phillips and Allen are looking over their shoulders! There are a couple of New Kids on the Block!

The new kids’ names are Torx and Pozidriv. The names may sound foreign but they fit right in the machine screw neighborhood. More surface area and better geometry make these screws more resistant to cam-out — or stripping — as it is more widely known. KNF is still utilizing Phillips and Allen head screws but Torx and Pozidriv are definitely making their presence felt.

TORX

Figure #1 (click to enlarge)

Torx are called “star drive” by some, as the recess resembles a 6 pointed star. The six points of contact engagement allows for higher torque being applied than a conventional Allen hex drive of the same size. Torx sizes are denoted by a T, followed by a number from 1 to 100. Common sizes used for KNF products include T6, T10, T15, and T25.

Various Torx screws and drivers are depicted in Figure #1 (left); shown clockwise (from top-left): various Torx screw heads, Torx handles, Torx driver, Torx black & white image.

POZIDRIV

Figure #2 (click to enlarge)

Pozidriv screws are almost a cousin to Phillips. The Pozidriv (sometimes spelled incorrectly as “Pozidrive”) is actually an improved version of the Phillips screw drive. The name is short for Positive Drive. This screw recess is very easy confused with Phillips if not noticed. Using a Phillips driver for Pozidriv screw recesses can easily result is a stripped head due to the different geometry of the driver itself. The Pozidriv has additional ribs in the driver tip which are received by the secondary web of the Pozidriv screw itself. This extra feature provides more turning strength due to the higher tool engagement. Figure #2 show various Pozidriv screws and drivers; shown clockwise (from top-left): Pozidriv screw heads, Pozidriv handles, Pozidriv driver, black & white image of Pozidriv.

Pozidriv drive bits are designated by the letters “PZ” plus a size code of 0, 1, 2, 3, 4 or 5. Common at KNF are the 0, 1, and 2 sizes. The drivers themselves will have a PZ marking and size code, and possibly the Pozidriv image on the handle butt.

The Pozidriv screws are visually distinguishable from Phillips by a set of radial indents set at 45° from the main cross recess on the head of the screw. These markings are sometime hard to see on plated or treated screws as the treatment may fill in the slighter 45 degree markings.

Please take care to look at these screws carefully before removing for service. Using the right driver will make your servicing quick and efficient. If you are in doubt of which screw is used on your KNF pump, please contact us. We are here for you.

WELCOME TO THE NEIGHBORHOOD

They don’t make things the way the used to, and this can be a good thing, since the latest tools usually incorporate technological advances that improve performance. Please give the “New Kids on the Block” a chance, they are proving to be hard workers!

Is It Time To Replace Your Water Aspirator?

A water aspirator is a simple device capable of creating a low strength vacuum for many standard laboratory applications. Though they are inexpensive to purchase and easy to use, the long-term operating costs and environmental impact of laboratory water aspirators can be quite significant.

The above video from Lab Manager follows Linda the Lab Manager as she and her colleagues investigate the real costs of owning and operating a laboratory water aspirator.

Chef Mario Waldispühl Uses KNF Rotary Evaporator to Concoct Culinary Creations

Mario Waldispühl is a young, enthusiastic kitchen chef of the Gasthof Krone Blatten restaurant in Malters, Switzerland. The native Lucerne chef is known for his creative and colorful cooking style which starts with fresh, seasonal ingredients grown locally throughout the region. From there, the chef and his staff apply imagination, a passion for cooking, and a love of food. This formula results in astonishing culinary combinations – a true feast for the eye and palate.

Whether he’s developing an elaborate multi-course menu, or making a ground-standing stew, the culinary talents of chef Mario Waldispühl extend well beyond the kitchen. Only a few months ago, the talented chef surprised attendees of the ILMAC exhibition in Basel, Switzerland by providing high-end, culinary creations to visitors at the KNF booth. Perhaps even more surprising than the location of the high-quality fare was the means by which they were created – using a KNF RC 900 Rotary Evaporator!

Mario Waldispühl explains the benefits of cooking with KNF’s RC Series Rotary Evaporator, and discusses his love for cuisine in the October, 2016 edition of KNF Neuberger, AG magazine, “Notabene” (German). The interview provided below is an excerpt from the English translation of the original article.


  1. While we are doing this interview, the summer season is already coming to an end, but the summer season Menu in Gasthof Krone Blatten is still up. – Which food would you order?”
    “Clearly the basil ravioli! By the way, it’s the dish from the summer menu, which I cook best.”
  2. Do you have a culinary wish that you have not yet met?
    “Fresh Maine lobster in a restaurant on the coast of Maine.”
  3. Is there a dish from your childhood that you have never got close to, what is your subjective opinion?
    “Grandma’s dumplings! In such taste memories, of course, it is above all about feelings, about emotional bonding.”
  4. Let’s go from the “normal kitchen” and the emotions into the world of technology. Cooking with a rotary evaporator – when did you hear about it for the first time?
    “About 10 years ago the molecular kitchen was very popular. This is where the rotary evaporator plays an important role. Because with it one can quickly and easily separate liquids, distill and boil at very low temperatures. The boiling point is considerably lower under vacuum; A tomato sauce, for example, boils in the rotary evaporator already at 40 degrees, whereas in classic cooking, between 70 and 80 degrees. I think every ambitious, modern chef dreams of cooking, experimenting with a rotary evaporator. For me it was so, but the devices are not quite cheap.”
  5. How did you get your rotary evaporator dream come true? Or in other words: How did you get to your rotary evaporator?
    “I was lucky! I have a regular guest working at KNF Flodos. One night I was talking about the rotary evaporator and he asked if I were tempted to cook with one . And so it happened that I came to an RC 900 from KNF and to return the favor, I will cook at KNF’s Ilmac booth.”
  6. When this article is published, the exhibition is already over – and the “culinary secret” has already been aired. Can you tell us, therefore, with which delicacies you would like to pamper your guests?
    “We start with a drink with chili and limes. Then there is tuna with chili, wasabi, seaweed- an indescribable taste experience! For dessert the main components will be chocolate and chili. And yes, chili did it to me; the results obtained with this spice with the rotary evaporator inspire me absolutely – an aromatics-technical revelation! We were able to hide the sharpness of the chili peppers, while the taste is fully revealed. So our “Little Experiment” at the fair is also very suitable for people who do not eat hot (spicy).”
  7. The RC 900 Rotary Evaporator from KNF is designed for laboratories. Is there something you think you should modify so that it is suitable for use in gastronomy?
    “No not at all. It is perfect for us as it is – no changes! Except when KNF would develop a model that cleans itself, then … Fun aside: It is in the nature of the matter that we need a lot of time to clean the RC 900, but this is easy and can not be changed. But you can dream.”

Video: Choosing the Best Vacuum Pump for Your Lab Application

 

Are you in the market for a new laboratory vacuum pump? Perhaps you need more information on which pump to choose. A new video, produced by Lab Manager, may provide valuable insights. View the video directly above, or click here.

Reaction Time: Q&A with Jim Abbott, Market Manager, Julabo USA, Inc.

PITTCON mascot, Pete Con, standing beside the Julabo reactorNot too long ago, while attending the PITTCON show in Atlanta, Georgia, we came across a unique and eye-catching exhibitor system – a special reactor manufactured by Julabo USA, Inc. featuring two KNF SIMDOS® liquid metering pumps transferring fluids to and from the reactor vessel. The machine is quite intriguing on its own; however, after having noticed the two KNF liquid diaphragm pumps, we contacted Jim Abbot, Market Manager, from Julabo USA, Inc. to learn more about the company’s impressive reactor.

1. Overall, what is the purpose of this reactor, what exactly does it do? Does it have an official name?

“We typically just refer to the small reactors of 100mL to 5L size as ‘bench scale’ or ’bench top reactor’, and the 10L to 100L sizes as ’kilo-scale pilot plant reactors’. Systems are available in both glass and stainless steel. Also, we are proud to be the US distributor of Berghof high pressure reactor systems – these have a ton of applications which they are used for but typical uses include: pharma, bio-pharma, plastics, paints, polymers, adhesives, petrochemical, energy, and most recently cannabis. The reactors are primarily used in mixing applications but with add-on features they can be easily equipped for various distillation methods such as: refluxing, short path and fractional distillation. All of our units are automation capable and can be easily controlled using our PC or PLC based AUTOReactor™ control and data logging packages.”

2. What is the function of the two KNF SIMDOS® pumps used within the Julabo reactor?

SIMDOS_Pumps_2 SIMDOS_pumps_1“We use the KNF pumps to control liquid additions or product sampling. The KNF SIMDOS pumps are used, specifically, because of their high quality, reliability, and automation capability. The pumps are connected to our PC or PLC based AUTOReactor™ control and data logging packages which allows users to program and control the process quite effectively and efficiently.”

3. I noticed that the reactor uses both KNF SIMDOS 10, and SIMDOS 02 pumps. Is there a reason why two different KNF SIMDOS pump types were selected?

“We displayed both [pumps] on [our demo] system, but typically we use the SIMDOS 02 on the bench scale reactors, while the SIMDOS 10 is used on the kilo-scale reactors. This is because of their different delivery rates as associated with the scale of the process, but quite often these are used interchangeably across both platforms.”

4. Is there any particular reason that compelled the system’s designer to choose KNF pumps over other dosing pumps from other pump manufacturers?

“We (Julabo) have had a long relationship with KNF both in the USA, and around the world. Moreover, we know without a doubt that KNF has the same principals as JULABO as far as delivering high-quality, reliable products.”

5. Will the Julabo reactor(s) be featured at the ACS tradeshow next week?

“Yes it will; we plan to display it again with the [KNF SIMDOS] pumps in a different configuration but always taking front stage, hand-in-hand with the JULABO products.”

6. Would you like to share any additional facts, or interesting notes regarding this system?

“We are devoted to offering our expertise in temperature control and reaction systems to our customers. Likewise, we are dedicated to providing solutions, from the inception of a process, through scale-up, and into manufacturing. One of the key factors is we design all of our systems with the utmost flexibility so as processes change, and companies grow we to can change and grow together with them.”

Julabo will be exhibiting at the upcoming ACS tradeshow in Philadelphia on August 21-23, 2016. If you will be attending the show, then be sure to check out Julabo’s incredible reactor system(s) incorporating KNF SIMDOS dosing/metering pumps. Also, don’t forget to visit KNF booth #1626 to see our latest laboratory technology, including: SIMDOS 10 and SIMDOS 02 liquid metering/dosing pumps, LABOPORT diaphragm vacuum pumps, LIQUIPORT liquid transfer pumps, the versatile VC 900 vacuum controller, and KNF’s award-winning RC 900 rotary evaporator.

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.
