Beckman Coulter Multisizer™ 4$ Please call for current pricing & availability
The Beckman Multisizer™ 4 is one of the most versatile and accurate particle sizing and particle counter analyzers on the marketing today.
Beckman Multisizer™ 4 – Electrical Sensing Zone
The Beckman Multisizer™ 4 uses the coulter principle or electrical sensing zone (ESZ). This method allows the Beckman Multisizer™ 4 to return distributions in number, volume and surface area in a single measurement.
The overall sizing range of the Beckman Multisizer™ 4 is 0.4 µm to 1600 µm. The response is not affected by particle shape composition, refractive index or color.
Beckman Multisizer™ 4 – Electrical Sensing Zone
Coulter principle is the leading technology in high resolution and accuracy. The Beckman Coulter Multisizer™ 4 enhances this even further by using the Digital Pulse Processor or DDP. DDP produces ultra-high resolution, multi channel analysis and accuracy that is otherwise unattainable by similar technologies. These features make the Beckman Multisizer™ 4 ideal for any research project involving sizing and or counting.
The Multisizer™ 4 is also an equally powerful tool for quality control. Analysts now have an easy to use system that is so advanced, it can solve most particle sizing problems. The Beckman Multisizer™ 4 is the latest coulter counter that is designed with Smart and DDP technologies offering highly reliable and accurate particle counting and sizing.
The Beckman Coulter Multisizer™ 4 retains the enhanced analog circuits developed and refined by Beckman Coulter over many years. It was the Beckman Coulter Multisizer™ 3, which first introduced DPP to particle counting.
Beckman Multisizer™ 4 – The Digital Principle Coulter incorporates the latest advances in both analog and digital circuits. High speed digitization of signals enable the use of multiple parameters for more accurate particle characterization. Dynamic size measurement is now a reality in the Beckman Multisizer™ 4. Measurements for each particle are analyzed and stored; the stored data can then be analyzed and formatted in a number of ways. The stored data may also be re-analyzed at a later date. With the Beckman Coulter Multisizer™ 4 there is no need to analyze the same particle twice.Proven Technology
