Thank you!

Hello, we do not have any openings for that position currently. You are welcome to review our current openings at www.parrinst.com/company/employment-opportunities/.

Thank you Mr. Ahmed. We are grateful to you and to M/s. Ghiath M Kaki Est. for our successful collaboration.

Thank you for your comment. I assume that you are trying to get the START button active. The START and START PRETEST buttons are deactivated if the heater and pump are off or if the jacket temperature is out of tolerance. The tolerance for the jacket temperature is 29.5 to 30.5 C. Once the jacket temperature reaches that range it will take an additional 15 minutes before the buttons becomes active to make sure that the temperature is stable. To disable the START button, just turn off the heater and pump. If you need any additional information please feel free to call us at (309)-762-7716 or or send an email to parr@parrinst.com and one of our Calorimeter Technical Representatives can assist.

Please contact us at parr@parrinst.com so we may get further details and your contact information.

I'm sorry we are not able to make such a video at this time. We often use Swagelok fittings on our reactors, their website www.swagelok.com might be of use for you. You may also email us at parr@parrinst.com for further assistance.

Hello Barbara, Thank you for your comment. There are many components of the 6400 that can cause noise in the system. Depending on the age of the instrument, this can either be a sign of a component that needs to be replaced or normal operation. The exhaust of the pressure from the inside of the combustion vessel can be somewhat surprising at first. 450psi of oxygen is being release from a 3/8” diameter tube into a smaller collection vessel. The vessel is also rinsed/washed a few times to ensure that everything is clean. This uses the same 450psi of oxygen pressure. If this is an issue, the tubing from the exhaust and vent connections for the back of the calorimeter can be plumbed to a larger container or to a space outside of the lab. If you need any additional information please feel free to call us at (309)-762-7716 or or send an email to parr@parrinst.com and one of our Calorimeter Technical Representatives can assist.

Thank you for your video suggestion. We will add it to our list. In the meantime, please contact us at parr@parrinst.com if you would like one of our technical representatives to assist with your operating questions.

Hello Mr. Ahmad, we would be happy to help. Please email us at parr@parrinst.com.

No, this is not available in current Parr calorimeters.

@@ParrInstrumentCompany thanks,

Hello Samvel, please contact us at parr@parrinst.com so that we can help you.

We don’t have a 4848 operation video currently, but we could certainly create one in the future. In the meantime, the 4848 operation manual can be found at: www.parrinst.com/products/controllers/4848-reactor-controller/documents/. You’ll need to log in to access the manual. And don’t hesitate to contact Parr customer support with questions at parr@parrinst.com!

@@ParrInstrumentCompany Thank you very much, and I look forward to seeing your video!

Hello! Thank you for your question. The vent line is used to depressurize the oxygen fill line inside the instrument. After the oxygen filling is complete the oxygen fill solenoid is de-energized and the tubing vents out the vent line. When this happens the pressurized gas inside the vessel causes a check valve to seal the chamber.

Thank you Neurin!

Thank you for the feedback. We will look into getting that added.

Thank you Neurin!

Thank you Munnuru!

It is hard to tell why exactly those cokes burned longer than coals. Generally the rate of combustion is defined by many things, however primarily it is driven by rates of combustion of the components in the sample, as well as the available surface to the oxygen. Provided that both of those samples have the same particle size, our guess here is that coal burns faster due to higher organic content, whereas coke in comparison is mostly carbon, which burns slower.

Well, thank you for responding update.

Hello Rajesh, We currently do not have an installation video for our 6200. The best source for installation is our 6200 Operating Instructions that may be downloaded from our Instruction Manuals page at www.parrinst.com/support/downloads/manuals/. We would be happy to provide further assistance as needed, please contact us at www.parrinst.com/contact/parr-usa/.
