Automatic Density Meter LBDM-A12

. Labtron’s Automatic Density Meter LBDM A12 handles a wide range of samples—from water-based solutions to hydrocarbons, solvents, alcohols, oils, flavors, and pharmaceuticals. Designed for QC, R&D, and production environments, it supports applications like API testing, beverage alcohol concentration, fuel quality checks, and chemical formulations. Capable of both automatic and manual injection, it adapts to diverse workflows and sample viscosities. Industries like petrochemicals, brewing, pharma, cosmetics, and academic labs rely on similar meters.

Labtron supplies premium automatic density meter LBDM-A12. Equipped with onboard memory (32–64?GB), the meter stores extensive data logs, complete with timestamps, user IDs, and audit trails. Data export supported through USB, RS 232, Wi Fi, and U disk enables PDF, Excel, and LIMS compatible formats. Features like electronic signatures, multi-level access, and encrypted data support regulatory need. USB ports and network interfaces make it easy to connect with PCs or printers, enhancing lab automation and traceability.

Routine calibration using certified standards (e.g., air & water or multiple density liquids) is recommended—typical intervals range from monthly to quarterly. Periodic cleaning, particularly of the U tube, ensures accurate oscillation and avoids sample build-up. Bubble sensors and temperature control systems should be checked during preventative maintenance. Manufacturers like Rudolph offer service plans with calibration, repair, and warranty coverage for decades. Regular firmware updates may further optimize measurement stability and feature sets.

Labtron’s automatic density meter LBDM A12 uses the widely respected oscillating U tube method, where the vibration frequency of a U shaped glass tube varies with sample density. Modern density meters often incorporate viscosity correction and use reference oscillators to ensure stability across different sample types and conditions. The Peltier temperature control maintains stability, which is critical because even small temperature changes can affect density readings by parts per million. Bubble detection systems like Filling Check ensure that trapped air doesn’t skew results These combined technologies allow sub ppm accuracy and exceptional reproducibility.

Labtron’s automatic density meter LBDM A12 features a built-in automatic sampling pump, enabling programmable filling and rinsing cycles for seamless, hands-free operation. This ensures consistent sample handling, reducing operator variability and contamination risk. You can adjust sample volume and flow rate via the touchscreen interface to suit different fluids. Automatic sampling speeds up throughput, which is especially useful in QC or high-volume workflows. Manual sampling is also supported if needed. Combined with touchscreen guidance, this supports simple operation with minimal training. Fully automated routines improve reproducibility and lab productivity.
