BrandTech Scientific Titrette Bottletop Burettes with RS232 Interface are advanced, precision instruments designed for direct, digital titration from a reagent bottle. Available in 10 mL, 25 mL, and 50 mL nominal volumes, they meet or exceed Class A error limits for glass burettes (DIN EN ISO 385, ASTM 287) while offering unmatched convenience, safety, and accuracy.
Key Features:
- Operates within Class A tolerances for glass burettes, ensuring rigorous accuracy for critical titrations.
- Digital volume display eliminates meniscus reading errors and enhances GLP/GMP compliance.
- Microliter precision enables drop-by-drop titration with drop sizes as small as 20 μL (model dependent).
- Automatic recognition of filling vs. titration modes eliminates manual switching, reducing handling errors.
- Large, ergonomically designed hand wheels and optimized gear ratio ensure rapid filling and ultra-sensitive dispensing.
- Easy Calibration technology allows tool-free, user calibration for quick adjustments.
- Optional RS232 interface provides direct data transfer to PC systems for secure, GLP-compliant documentation.
- Lightweight, compact design ensures stability on bottles and ease of transport without external power requirements.
- Amber inspection windows protect light-sensitive reagents.
- Disassembles easily for thorough cleaning, maintenance, and battery replacement.
