Zetasizer Pro

I usually use Zetasizer Pro Red to analyze the aggregation state of biomolecules. The biomolecules were labeled with a fluorophore that sometimes hindered the analysis because of overlapping the excitation wavelength. However, this equipment has a narrow band filter that cuts off the excessive fluorescence from the fluorophore emission so that my experiment was successfully accomplished. I tried several DLS devices, such as Otsuka, Horiba, Shimazu, and so on, but Malvern's is the best for my research. Also, the aftercare service is satisfied.

Highly recommended, Zetasizer is used in our R&D and QC lab for routine nanoparticle size distribution applications. This eeliable and very sensitive instrument allows for an in-depth bottom-up characterization of our injectable products.

The product is very effective for my use. Polymer growth is a key part of my research area as it proves that the chemical reaction in my research is taking place. The Zetasizer is easy to use as there is no specific sample preparation that needs to be done for the size feature. Simply pouring the samples in a disposable cuvette and placing it in the machine is adequate. Apart from that, the built-in software was easy to handle since it follows a step-by-step process with instructions for each step which helps the user to identify what is required. Moreover, the results are processed fast hence, preliminary investigations can be easily done using the Zetasizer. Since I use it in my university lab, whenever there has been an issue, the supplier came in to do the necessary changes, calibrations or repairs. I am not involved in the purchasing department, but in terms of value for money, the instrument has various features incorporated into it, with a useful software so I believe it serves its purpose well.

This DLS is a user friendly instrument. You can use it with confidence even if you are a first time user. So easy to manipulate and understand. What keeps it more interesting, is it’s fast release of results with accuracy. I used three to five replicates of my sample analysis and it gives me precise results. Thus, make me confident to analyze and write my results into paper for publication. Hope it will be accepted for publication. Thanks to Malvern Panalytical - making dreams come to reality.

The Zetasizer is one of the most user-friendly pieces of equipment I've used so far in my career. The instrument itself is easy to set up and operate. It has demonstrated high sensitivity for size measurements, and the datasets I've collected are consistent and reproducible. The ZS XPLORER software is overall a very effective package, although I think it could use some tweaking regarding how the Options panel identifies source folders for .zmes files, especially on a multi-user workstation. Additionally, it would be really nice if the real-time read out window of the Measurement tab would show a live reading of volume as well as intensity if possible. It would also be nice if there was an option for exporting raw data in an Excel format. I work specifically with the low volume capillary apparatus, and I have found that this is a highly effective tool for what I am studying. The capillaries are disposable, but the ease of ordering them online could also use some improvement. My lab manager has previously stated that it is difficult to navigate the Malvern website re: ordering consumables. However, when communicating with sales representatives by phone, we have had great customer service. The on-site representative has been extremely helpful in training me on how to use the instrument, as well as data interpretation. Overall, I highly recommend this instrument, but think the software could use some minor improvements.
