Bettersizer 2600 Particle size Dynamic image analysis Laser diffraction

Bettersizer 2600 Plus combines laser diffraction and dual-camera dynamic imaging on one modular platform, delivering size and shape characterization across 0.02–3500 μm. Laser diffraction provides fast, repeatable particle size distributions using a 92-detector array and Mie/Fraunhofer models. Dynamic imaging captures high-speed particle images to quantify size and shape, with visual evidence for agglomerates, irregular particles, and oversized tails. With a modular design, Bettersizer 2600 Plus supports a broad selection of wet and dry dispersion units. This enables flexible setups for different sample types, volumes, and solvents, so one instrument can meet diverse applications and industries

  • Outstanding service

    I have been using Meritics for a number of years and they always provide outstanding service and support.
    They have a rapid response turnarounds and are very knowledgeable of the techniques and products they provide.

    LeanneB-375

  • Good service, very helpful

    We use Meritics for the PM service and installation of all our FlowCams . Megan has been coming to our site for a number of years. She is very efficient in her work, but most of all Megan is very helpful. We have had issues with one of instruments after the install and Megan did her utmost to try and solve it while on site, even though it wasn’t solved Megan has been in contact with the supplier of the instrument to try and solve this problem for us.

    David, our service engineer as usual was good at communicating and setting up the recent service appointment, he arrived on time, did the service promptly and informed me of any problems. Friendly and helpful

    TomA-446

  • Superb and prompt service

    I have used this company through the laboratory I work for frequently. We specialise in soil analysis, and Meritics were chosen as they have extensive knowledge of the instruments we use. We have several laser particle diffraction analysers with a service contract, and service is always very prompt and meticulous….

    JamesG-2483

  • Good experience over two years

    Meritics have covered the annual servicing of our Multisizer 4e instrument since we purchased it from them just over two years ago. The application scientist who performed the servicing was friendly, knowledgeable, and extremely helpful, happily answering a barrage of questions about how best to use and maintain the instrument. All my interactions with Meritics staff have been positive. I would happily recommend them.

    RajG-62

  • Fully committed to customer service

    Service second to none, both units serviced and all questions answers by engineer while on site.

    RichardA-786

  • Highly recommend Meritics for equipment purchases and aftercare services

    After owning one of our instruments for over 8 Years which was purchased from Meritics, it suffered its first breakdown. Upon contacting Meritics, I was instantly put through to an engineer who was very helpful. Upon inspection of the manual, it was decided that it would be more cost effective to have a Meritics engineer visit. The Meritics staff were very communicative and kept me up to date.

  • Excellent Service

    Lovely, friendly and extremely helpful. David and his team are always on call with advise and are very easy to work with and are always happy to help.

    NaomiT-64

    Friendly and collaborative staff, provided a very good service.

    SamK-403

  • Professional, Customer-oriented, fast service

    We had issues with one of the aperture tubes provided by Meritics on a Friday afternoon, while very pressed for a review deadline. Meritics handled our inquiries very fast and professionally and helped us out by shipping us their spare tube to use in the mean time free of charge, while we waited for our new tube to arrive. Communication was very pleasant.

    VeerleB

  • Very helpful and prompt

    I emailed for some technical help and also to get some spares and both the engineer (David) and purchasing (Sophie) were very prompt to respond and helpful. We do have a service contract but I appreciated being able to email the engineer directly.

    AlexH-474

  • Excellent Service

    Used Meritics to conduct particle size distribution by laser diffraction. Service as last time, is very quick, well priced and professional.

    I would highly recommend

    GavinR-101

  • Excellent and Friendly Service

    Always a pleasure to deal with the people at Meritics Ltd. They understand the importance of our work and the fact that our research projects have deadlines that need to be met. Consequently, problems are dealt with very quickly and professionally and they are willing to go that one step further to make sure their supply chain problems don’t become our problems. Thank you to the team for their support. It is greatly appreciated.
