It replaces the previous model of folded capillary cell while providing the same ‘plug and play’ convenience for easy application and. Additionally, the item must arrive back to us undamaged and in the original condition in which it was sold-no modification, alterations, etc. Malvern Instruments has introduced a new, improved disposable folded capillary cell for use in its Zetasizer Nano particle and molecular characterization systems The new cell is designed to further enhance the reproducibility of zeta potential measurements. We will refund the purchase price of the item, however, the buyer is responsible for return shipping in this case. A 30-day return period also applies to items that arrive in the condition described in the listing. Measuring surface zeta potential An accessory cell for the Zetasizer enables a small piece of the at sample to be mounted between two electrodes. We will cover the return shipping on warrantied units.Ĭontact us if you have any questions or concerns. We offer a 30-day DOA warranty on all of our items EXCEPT those listed for parts or repair.

Primarily for the measurement of zeta potential with the Zetasizer Nano and Zetasizer Advance ranges, but can be used for size measurement with. Only the items shown in the picture are included (besides the power cord). Folded Capillary Zeta Cell (Box of 10) Description. Malvern Instruments Limited Printed in England MRK0499-02 Enigma Business Park Grovewood Road, Malvern Worcs, WR14 1XZ, U.K. It does not include any other accessories or computer.
#Malvern zetasizer cell series
Compatible with all Zetasizer systems including: Zetasizer Adavance range, Zetasizer Nano series and Zetasizer V. We are not set up to fully test and verify the equipment. Used for calibrating Zetasizer Advance Systems capable of Molecular Weight and MADLS Partilce concentration and for checking the scattering intensity of other systems with a size measurement capability. In addition to zeta potential measurements, the Zetasizer Nano instruments measure particle and molecular size from below a nanometre to several microns, electrophoretic mobility, and molecular weight.The unit was carefully removed from a working laboratory setting and was said to be in good working condition. Malvern Instruments Worldwide Sales and service centres in over. The application note ‘Determination of the zeta potential of the surface of PTFE’, and others relating to different aspects of the measurement, can now be downloaded from Malvern’s online knowledge centre: Īdding the surface zeta potential measurement capability to Zetasizer Nano systems opens up new applications in areas of research that include understanding and optimizing surface coatings, studying biological materials such as teeth and bone, and evaluating the effect of environmental changes on polymers or glass. Table 1: Size, molecular weight and zeta potential cells available with the Zetasizer range. Malvern’s Surface Zeta Potential Cell eliminates the need for a dedicated solution, allowing users to measure the zeta potential of surfaces in an aqueous medium on a standard instrument. Widely used as an indicator of the stability of particle suspensions and colloidal samples, surface zeta potential is traditionally measured using the specialist technique of streaming potential. A series of new application notes posted on the Malvern Instruments website describes the quick and easy measurement of surface zeta potential using the zeta potential planar cell for the Zetasizer Nano particle characterisation system.
