Electrode Shower Cleaning for Auto Titrator Sample Changers

By Hank Levi on Thu, Feb 25, 2016 @ 12:04 PM


ELECTRODE RINSE WITH SHOWER ACCESSORY:

Sample changers that are connected with automatic titrators generally are there for a reason.  Efficiency. From an operators point of view getting multiple tests done quickly while being able to take on other tasks in the lab is a key productivity booster.  Sample changers offer various sizes ranging from as few as 6 positions for samples up to some of the largest exceeding 50 sample positions.  Sample changers either have rotating carousels or an arm that moves electrodes and nozzles from sample to sample.  Each time a sample test is completed the electrode must be cleaned before moving on to the next test.  Many sample changers offer as standard a dip rinse between sample testing and as the name suggests it's really nothing more then dipping the electrode in clean water or solution.  For some samples this process is sufficent but for others it is not enough to effectively clean the electrode before the next test.  Luckily most manufacturers of sample changers offer additional cleaning power with the use of a shower rinse system.   Below is a video showing how a shower rinse process works.   Water is stored in a container and then is flushd and rinsed in one of the sample positions designated as the cleaning station.  Water is evacuated via tubes to a drain or sink.

Review of KEM's new 2015 titration line

By Hank Levi on Tue, Jun 09, 2015 @ 04:11 PM


Review of KEM's new 2015 titration line 

AT-710S_M Automatic Titrator

I don't know about you but I have to admit that I enjoy learning about new technology.  Whether it's smart phones, cars, or kitchen appliances I think it's fun to find out about how a product has changed (hopefully for the better). For the most part a lot of consumer products see a change or upgrade about once every year. This is not really the case for titrators where maybe it's only every 6 to 8 years before we see a new generation unveiled.  I guess that's why I thought maybe it would be a good idea to take a look at this new 710 series that came out in February 2015.  I haven't actually ever written a "review" before so I decided to start by comparing what I know about some of the current titrator models and identify the things that pop out with the new titration line.   Here are my observations and comments.


Link to pictures and information about the 710 series titrators: http://info.scientificgear.com/kem-titrator-710-series-information


 

1. There are now three model levels; entry, mid-level, and flagship within each category (volumetric Karl Fischer, coulometric Karl Fischer, and automatic potentiometric titrator) 

My comment: I like the scale of the models as it can be helpful for those with varied budgets and needs.  I like the concept that you can start with getting only the basic model at first and then later bring in the flagship model and tie them all together into one system.  It will be interesting to see how people approach these options and whether the ability to expand a system is desirable or not.

2. All of the automatic titrators now can accommodate two burette drives

My comment: The automatic titrators come with one burette drive but being able to add a second burette drive allows an operator to run two separate titrations (titrants) without having to use an automatic piston burette.  Historically most titrator manufacturers offered only a single burette drive but it seems like this is changing.  It's kind of a big deal for those who run two different titrations and don't want to purchase an automatic piston burette.  I like this new capability.

3.  A new burette design for the automatic titrators and volumetric Karl Fischer titrators.

SmartBuretteUnit

My comment: The burettes appear they will be easier to store and swap as the titrant bottle, burette and nozzles all go together as one smaller unit.   The burettes are now "smart" burettes and can store all of the reagent information within the head of the burette.  I like this.

4.  More Input/Output options for operators to move  and store data.  I/O options include LAN connectivity/URL, USB hubs, USB thumb drive ports, .CSV file format, .PDF file format, barcode readers, foot switches, and keyboards.710seriesUSB

My comment:  More technology is built into these units. I think it was overdue so I am glad to see it finally arrive.

5.  Automatic Titrators now come with a propeller stirrer by default but can swap for a magnetic stirrer instead.

My comment: I like the option to do both but I think maybe the magnetic stirrer should have been the default and the propeller as the option.

 

6.  A new Wireless/ Wired 8.4 inch color touch panel controller (MCU).

MCU_screen_view_with_multiple_units

My comment: This only comes with the mid-range and the flagship models.  The controller can sit next to the titrator or be carried around like a clipboard.  Operators can control the titrator through protective glass if necessary.  I'm not sure how many people will elect to use the wireless vs. the wired connection but it's nice to have the added capability.  Nice.


7.  Multi-titrator integration.  The wireless/wired MCU can control up to 4 different titrators simultaneously (any combination of Karl Fischer or automatic titrator) 

MCU_controller for 710 series titrators

My comment: This feature is reserved for the flagship model.  I can see this being useful for those needing to run both moisture and acid for example.  Unfortunately the mid-level model MCU cannot be upgraded to the MCU flagship model so if you think you might expand later don't go with the S model.  Your better off getting the basic "B" model and then later tying them all together from the flagship model.

8.  Free method making software.

My comment:  All of the titrators now come with a CD that allows you to create methods on your PC and then transfer methods to the titrator.  You can also pull methods off of the titrator and edit it in the PC.  The software also comes with various popular methods pre-loaded to help get methods setup quicker.  I'm not so sure how robust this software is but free is nice.

CONCLUSION:

Well I hope this was helpful in finding out quickly what the updates are for the new 710 series.  At this point since it's so new we will have to wait to evaluate how customers feel about their user experience and get their feedback on what they liked most and what they liked least.  If you have any questions or comments you can email me at info@scientificgear.com

Automatic Titrator with Mini Sample Changer Video

By Hank Levi on Tue, Nov 20, 2012 @ 11:11 AM

AT-700 Automatic Titrator

The AT-700 automatic titrator provides operators a variety of choices including the use of an Mini Sample Changer CHA-700integrated mini sample changer.  The mini sample changer can hold up to 6 samples.  The design utilizes a rotating arm that holds the electrode(s), dispensing nozzle(s), and propeller stirrer above each sample and maneuvers from sample to sample.  The compact design allows a small footprint on the bench because the titrator sits on top of the sample changer.  Watch the short demo video to learn more about this titration system.

Sneak Peak at new Potentiometric Titrator AT-700!

By Hank Levi on Mon, May 09, 2011 @ 11:44 AM

Potentiometric Titrator AT-700
















 

 

 

 

 

Here it is!  The new AT-700 Potentiometric Titrator with integrated sample changer, CHA-700, is coming out soon.  Manufactured by Kyoto Electronics Manufacturing (KEM) this will mark their 7th generation of industrial grade, high quality, titration instrumentation.  We have not yet received all of the details on this amazing looking, newly designed potentiometric titrator but can tell you that it incorporates a carousel design sample changer that handles eight samples.  From the photo you can see how the sample changer's compact design revolves around the Potentiometric Titrator.  There are a few key design features on the new potentiometric titrator:

  • No need to read measurement parameters
  • New burette system
  • All-in-one compact design

We're told this new design will make significant improvements with the measurement of Mercaptans down to 1PPM (ASTMD3227,UOP163,IP272).

*Advantages include a special sealing cell and electrodes to avoid oxidization of mercaptan sulfer under atmospheric conditions.

*Application: Determination of mercaptan sulfer and hydrogen sulfide in fuels and liquid petroleum gases (LPG) is one of the important applications in petroleum and gas analysis.

We anticipate this newly designed Potentiometric Titrator will serve many other titration applications and provide operators with a compact yet fully automated functioning titrator.

As we receive more information on this new titration system we will let you know.
