ViewSizer 1000
Multi-Variable Pulse Nanoparticle Tracking Analysis (NTA)
- Measurement range 10 nm to 15 µm
- Advanced NTA with a single laser
- Repeatable results with minimal sample handling
Key Features
- Collect accurate data for all particles in a sample, even for wide-size distributions, using patented multi-variable pulse technology (MVP NTA).
- Excellent repeatability and reproducibility due to stable optics, temperature control, and effective, unbiased mixing.
- Access larger particle sizes with high spatial resolution NTA for slowly moving particles, including sedimentation analysis.
- Prevent cross-contamination and increase throughput by using easily washed and replaced cuvettes.
- Flexible analysis with user access to laser intensity, camera gain, pulse duration, and frame rate settings.
- Recommended and robust default method settings for many applications are included with the system.
- Solvent resistant (wetted materials: glass/quartz, fluoropolymers, and anodized aluminum, glass/fluoropolymer cells also available)
- Reduced sample volume due to no feed tubing or pump required.
Introducing Multi-Variable Pulse NTA
Using next generation hardware and software, a series of varying pulse widths are used in place of varying laser powers. Each pulse width has its own independent sequence of video frames. Long pulse frames have good data on small particles, while short pulse frames have good data on large particles. Position as a function of time, that is particle movement, is then analyzed by the Stokes-Einstein relationship to extract particle size for each particle in the sample.
Since sample volume is well known, along with the number of particles images, particle number concentration is determined without any further information required. Random mixing with a stir bar (not slow flow through a tube) ensures random selection of particles for each video without the biases of a flow-based system. The instrument automatically sums the particles identified in each video and divides by the measurement volume to calculate the sample concentration.
Thus, detailed particle size distribution and concentration is rapidly measured in a single system.
Advanced Software
The ViewSizer software is designed for intuitive workflow. Data collection can be initiated with just a few clicks, with results generated in multiple exportable formats for downstream analysis. The user interface includes real-time visualization of all particles – providing valuable insights into sample behavior and data quality.

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.

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.

Good Service
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

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….

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.

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

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.

Multisizer 4e install at pharmaceutical company
2 people helped with the install of a Multisizer 4e. They were both very professional and friendly, answering any questions that I had. The installation was quick and the attention to good documentation practice was exceptional.

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.

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.

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.
