The images provided are of the actual item you will receive. Please review them carefully for cosmetic condition.

This unit is in used condition and presents in very good cosmetic order. The system has been thoroughly tested — including filling, rinsing, needle positioning, sample handling, air pump, and camera functions — and is confirmed to be in full working order.

The following subsystems are active and registered on the instrument:
• DMA Density Module — v2.004.018
• HazeQC ME Turbidity Module — v1.000.028
• pH ME Module — v1.003.004
• Xsample 122 Sample Changer — v3.000.068
• DCB Environment — v2.003.022

The DMA 4500M has an Anton Paar Ltd. (UK) service label confirming Preventive Maintenance and Calibration was completed on 04/10/2023. Both the DMA 4500M and the HazeQC ME module carry current appliance safety test passed labels.

This lot includes the Anton Paar DMA 4500M density meter, the Xsample 122 automated sample changer with carousel magazine, the HazeQC ME turbidity measuring module, and all interconnecting cables and tubing as fitted.

The Anton Paar DMA 4500M is one of the world's most trusted benchtop density meters, delivering reliable 5-digit density values for laboratories where accuracy and reproducibility are paramount. It employs Anton Paar's patented Pulsed Excitation Method, which provides the most stable density results through comprehensive knowledge of oscillation characteristics, along with viscosity correction twice as effective as competing systems.

Key highlights:
- Patented Pulsed Excitation Method for best-in-class measurement stability and viscosity correction
- Automatic bubble detection via the built-in U-View camera ensures reliable filling every time
- Built-in intelligence compensates for operator variation, humidity, air pressure, and instrument condition
- Fully modular: connects to Xsample sample changers, HazeQC ME turbidity module, pH ME, and other Generation M peripherals via CAN bus
- Colour PCAP touchscreen with multi-level user access and password protection
- Compliant with ASTM, ISO, and pharmacopeial standards for density measurement
- The HazeQC ME turbidity module uses an approved three-angle ratio method (0°, 25°, 90°) at 650 nm, compliant with MEBAK and EBC standards, with a Peltier-thermostatted cell for stable measurements to ±0.01 °C
