BD50ML Automatic Digital Bottletop Dispenser with 32oz Glass Bottle for Precise Electrolyte Dispensing up to 50 mL
The BD50ML dispenser is engineered to meet the demanding requirements of electrolyte dispensing in lithium-ion battery research and related applications. It enables precise volumetric delivery of liquids up to 50 mL per batch, supporting workflows such as titrations and electrolyte preparation with high accuracy. Its compact design allows operation even within glove boxes under inert atmospheres, facilitating work with sensitive battery chemistries like Lithium-Sulfur and Lithium Solid-State cells.
This digital bottletop dispenser integrates a new generation measuring system that achieves Class A accuracy comparable to traditional glass burettes, providing readings with two decimal places. The instrument is user-serviceable, allowing quick disassembly for cleaning or part replacement without requiring external repair services. It also features interchangeable clear and amber-colored inspection windows to protect light-sensitive reagents during dispensing.
Key Features
- Class A volumetric accuracy with 2-decimal place digital readings compliant with DIN EN ISO 385 and ASTM E287 standards.
- Compact, lightweight design with internal moving components reduces headroom and enhances stability.
- Adjustable titrating tube for horizontal and vertical positioning to suit various container sizes.
- Large handwheels enable smooth control from rapid dispensing to dropwise titration.
- Interchangeable clear and amber inspection windows protect light-sensitive liquids.
- User-serviceable construction allows easy cleaning and replacement of piston, cylinder, and bottles.
