Dear Steve,
I would like to thank you and your team for doing an outstanding job in our engineered stenotic valve project.
At the beginning of this project we did not know how much of what we aim for can be achieved, or even if it can be achieved at all. Still, not only did you achieve it, you also did it on a very short schedule. Specifically I would like to note Roni's professionalism and dedication; Roni had an invaluable contribution to the success of this project and was a pleasure to work with.
Having a reliable bench model that can simulate the mechanical properties of a stenotic valve is very significant for our ability to evaluate our device. We appreciate your resilience and hard work and looking forward to our next collaboration.
Thank you,
Amir Revivo R&D Pre Clinic Manager
Dear Dr. Daren
AIMPLAS has had the pleasure of working with DARENLABs during the EC BRIGIT project. We were impressed by DARENLAB's project management and leadership skills.
DARENLAB’s staff are very dynamic and energized people, who would work very hard to accomplish their deadlines. On the top of that, Steve and their colleagues are excellent professionals with a very strong background in polymer/material science and excellent communicators.
They are open-minded, thinking-out-of the box, very result oriented people.

DARENLAB’s staff has a well-balanced and strong technical background along with the global commercial experience. The company is very focused and committed. It does not only demonstrate strategic thinking but also boundary-less behaviour to drive and manage cross-functional (diverse) team by leading them by example to achieve the business goal.

DARENLABS has a great network, contacts, interactions and relationships with potential suppliers and customers. It truly played an essential role in all our project developments, and they greatly support us in making our work a success.

I have cooperated with the Daren Laboratories for over 11 years. I came to them first with a request to synthesize new previously unknown organic molecules for which there was no established method of synthesis. After they performed this task well, rapidly and discreetly, I came back to them with requests for other and different molecules. The work was always performed to our satisfaction, rapidly and at reasonable costs. I also consulted Steve not infrequently on various difficult, chemical and other problems and always received valuable advice. Based on this rather extended period of cooperation I can recommend the laboratory and Steve personally highly. The lab is efficient, proficient and delivers a good product I can recommend them highly.

I have cooperated with Daren Labs and particularly with Steve. I approached them seeking for a scale up process development of calcium alginate microspheres with specific range of diameter. The work was performed to our satisfaction, at reasonable costs. I also consulted Steve not infrequently on various issues and always received valuable advice willingly given. Based on this cooperation I can highly recommend the lab and Steve personally.

Our work with Dr. Steve Daren started in 2007, when we needed to scale up the production of our micelle-clay complex from a laboratory production to a semi-industrial scale, which was needed for constructing a pilot filter for purification of water from perchlorate. The laboratory of Steve was well equipped and shining clean. He grasped the problems immediately and gave us useful suggestions which he carried out in his laboratory. Consequently we could avoid a long process of centrifugation by a combination of decantation and a use of a Buchner funnel, and have our complex produced on time. During our encounter we were impressed with the knowledge of Steve in the area of Applied Chemistry and the accurate and prompt execution, which also projected motivation and enthusiasm to his coworkers and employees.
Our encounter with Dr Steve Daren enabled us to widen our scope and helped us significantly in succeeding with our pilot. Later on we utilized the knowledge, experience and creativity of Steve in another area. He succeeded to develop a promising process of synthesizing our surfactant. His scheme when carried out on an industrial scale will reduce the price of the surfactant, which we employ by about 40%, which can make our water purification economically appealing and relieve us from being dependent on external sources.

To whom it may concern

We would like to thank Daren labs, mainly Elliad for their professional and efficient work they did during our conductive spray development.
Throughout the development, every specification requirement was considered and got a solution.
It is noteworthy the fast responds and the full willingness to resolve the difficulties that were generates during the development.
Furthermore, it is remarkable the Daren lab guarantee to the final product and the readiness to do the fine-tuning after the product submission

Thank you,

To whom it may concern

I'm pleased to recommend Dr. Steve Daren and The Company Daren Laboratories & Scientific Consultants Ltd. as very experienced in fine organic chemistry and physical chemistry.

MOBIChem Scientific Engineering Ltd. was working with Daren Laboratories & Scientific Consultants Ltd. during a few years over the project on development of ethylene scavengers for fruits and vegetables shelf life elongation and based on substituted tetrazines. Our company faced problems with scaling up of ethylene scavenger synthesis because of some particularities of chemical reaction. After starting mutual work with highly skilled staff of Daren Laboratories & Scientific Consultants Ltd. and kind consulting by Dr. Daren production of a few pilot batches of ethylene scavenger was launched with equipment of Daren Laboratories & Scientific Consultants Ltd. Comprehensive testing of made pilot batches of ethylene scavenger at final user (agricultural plants) showed its high efficiency as ethylene reactive additive in different polymer made packages.

Daren Laboratories & Scientific Consultants Ltd. is able to conduct both projects of pure science and those focused on practical issues for further implementation of development in industry. Thus production of ethylene scavenger developed in our joint work with Daren Laboratories & Scientific Consultants Ltd. was launched recently as industrial scale process.

I can recommend Dr. Steve Daren as a leader for any scientific project as well as a project focused on application purposes. Daren Laboratories & Scientific Consultants Ltd. is able to conduct with high efficiency projects in many fields of chemical science and industry.

I wish Dr. Steven and his Company all the best in all their intentions.
Sincerely Dr. Boris Gorelik
We would like to thank Daren laboratories for helping us promoting our development of Bio Cosmetics products.
Thanks so much for the Professionalism, your help and support. Thank you for your standing timetable and the courteous and pleasant service.
We highly recommend for those who need to carry out laboratory research, to use the laboratory and services of Daren labs. Hi Lee Team.
