This brochure for the Zetasizer II dates from around 1985 thats at least 35 years continuous service from a brand now synonymous with nanomaterial characterization Of course, it has been delivered in many forms, sizes and flavours over that time.However, weve also always known that if customers cannot use and understand something, there is no point to high-end researchand at the core of the Zetasizer has always been the desire to enable the practical measurement science which enables groundbreaking research.We are hugely proud of the Zetasizer and all it stands for, and also all the amazing science it has enabled over the years, all around the globe.It represents decades of friends and colleagues (including the occasional eccentric) working together to develop, improve, expand and nurture the system.
At the heart of every Zetasizer lies years of experience, and further years of listening to our users and making the system more accurate, more versatile, more simple, yet much more powerful. Every single Zetasizer is a labor of love and a celebration of technology. Find out how the Zetasizers journey started, and more importantly, where it is headed next. Cuvette holder The cuvette holder is for storing the cells before and after use.

The instrument measures the size of particles contained within a sample, presenting data according to the users needs. Zetasizer Malvern Manual Is AThis user manual is a companion to the Zetasizer Nano Basic Guide, which gives Health and Safety, maintenance, troubleshooting and other vital information which all users must read. Zetasizer Malvern Full Access ToMalvern Instruments personnel Malvern Instruments personnel (service engineers, representatives, etc.) have full access to the instrument and are the only people authorised to perform all service procedures that may require the removal of the instrument covers. The accessories or sample dispersion units are referred to as MPT-2 Titrator, the vacuum degasser, or as the accessory. The following topics are covered: A description of the purpose of the instrument, its accessories and simple. The models and their measurement specifications are described in the table below, with instrument options following. It is partic- ularly suitable for measurements of valuable aqueous samples where minimal sample quantity is important. High This is used to perform zeta potential measurements on a concentration. Greater detail on the measurement techniques is given in Part 2 - Measurement theory. Particle Size The particle size measured in a Dynamic Light Scattering (DLS) instrument is the diameter of the sphere that diffuses at the same speed as the particle being meas-. A more detailed explanation can be found in zeta potential theory chapter. Why do we use it A wide range of materials exist as molecules or particles that can be characterised by dynamic light scattering. Zeta potential is measured using a combination of the measurement techniques: Electrophoresis and Laser Doppler Velocimetry, sometimes called Laser Doppler Electrophoresis. Zetasizer Malvern Series Of InstrumentsWith the Zetasizer Nano series of instruments the molecular weight can now be determined by use of Static Light Scattering (SLS) measurement techniques. Why do we want to know it We need to know the molecular weight, so we can determine how many grams there are in 1 mole of a substance. Cells sample is presented in a selection of measurement cells so that it passes through the instruments laser path. Accessory output A 12v output supply is provided on the rear panel to connect to any Malvern supplied accessory that requires an external voltage source. When operating at a humidity higher than 50, the measurement should. Cell area Warning The system is capable of heating the cell to high temperatures. See the Inserting the cell section in Zetasizer Nano accessories guide for precise details on fitting the tubing. This ensures the cell clamp moves freely, and that no spilt sample has caused the mechanism to stick.
