150 around 100ºC but we cannot go to pressures of 200-300 kPa (which in the case of alcohol or water mixtures are necessary in order to establish liquid-vapour equilibria inside the chamber). I am sorry that I can not help you.
Good luck with your wok,

Hi,
We do not have the means to measure against pressure.
Kind regards.

Dear Sir:
I am sorry to say that I have retired and my lab has been dismantled.
The surface tension equipment has been moved to the lab of Dr Michael Pegg. I am not sure if he has an available technician to do this work for you.
I am copying this email to him and he will get back to you if he is able to do this for you for a fee.

Contact four:
Mahabubur,
Thanks for your interest in our interfacial tension analysis service. However, I regret to say that we do not have capacity to help this autumn. Please, note also that although production of reference data for pure systems like those mentioned is valuable as such, we work on a commercial basis and would have to charge for such services. Our services are aimed at the oil industry and our instruments are designed for very much higher
158 pressure than 200-300 kPa. If you can find some laboratory at a university doing interfacial tension measurement at the relatively low pressures you request, I think that would be your best option. Such instruments would probably be better suited for the requested pressure range, the work would be less expensive (our services are maybe too expensive to be charged to a private person) and you might find someone who could collaborate with you one the publication instead of charging for the service.
Best regards Bard Bjorkvik

Good day,
I hope this email finds you well. I am writing to you in regard of measurement of surface tension at high temperature and pressure. I have read an article from SINTEF regarding the surface tension measurement (I have attached the pdf), My research field is in material science. I have submitted a paper in the Journal of crystal growth, which evaluates the functional relationship between solvent surface tension and particle growth rate. However the editor will only accept the paper if i show the surface tension of the solvents at hydrothermal conditions (at 100 degree c and 200-300 kPa) I would like to know if you can assist me with measuring the surface tension of 4 different alcohols, (Pure alcohol: 1. methanol, 2. ethanol, 3. propanol and 4. butanol: and also 50: 50 mixture of the same alcohol + water) at this specific temperature and pressure? You can charge me with the cost to run the experiments or you can co-author the paper as it will be accepted once the data is provided and the paper is revised. And also this experiment will provide novel data as high temperature and
159 pressure surface tension measurements of these four alcohol is not presented in the literature. So you can decide how you would like to do this, either co-authorship or charge me for your service. Please let me know. I thank you in advance and hope to hear from you soon.

Good day Prof. Lamia and Dr. Piri,
I hope this email finds both of you well. I am writing to you in regard of measurement of surface tension at high temperature and pressure. Your contacts were forwarded to me by Bård Bjørkvik from SINTEF Norway.
My research field is in material science. I have submitted a paper in the Journal of crystal growth, which evaluates the functional relationship between solvent surface tension and particle growth rate. However the editor will only accept the paper if i show the surface tensions of the solvents at hydrothermal conditions (at 100
