Achieving high-precision volumetric analysis requires specialized glassware designed for controlled, drop-wise liquid delivery. Professional laboratory burettes, available in automatic and traditional configurations, provide the accuracy needed for complex titration protocols. As a critical component of our liquid handling and titration ecosystems, these tools ensure repeatable results for chemical and clinical research.
Why Choose Professional Burettes?
Our curated collection of titration instruments is engineered for chemical resistance and technical compliance:
- Automatic Schilling Titrators: We stock BRAND Titrator Schilling systems in 10 mL, 15 mL, 25 mL, and 50 mL capacities, featuring PE-HD reservoirs for rapid, automatic zeroing and easy refilling.
- High-Accuracy Glassware: Utilize Hirschmann Laborgeräte Burettes made from premium DURAN® Glass (Class A), providing the tightest tolerances for analytical chemistry.
- Maintenance-Free Stopcocks: Select ISOLAB Burettes equipped with PTFE stopcocks, which require no greasing and prevent seizing when used with caustic reagents.
- Diverse Scale Options: Find the ideal resolution for your titration with graduations ranging from 0.02 mL to 0.1 mL across our glass and plastic-coated ranges.

Frequently Asked Questions
1. What is the benefit of a Schilling-style burette?
The Schilling burette is an "automatic" titrator that includes a reservoir bottle; squeezing the bottle fills the burette, and it automatically zeros, making it much faster for routine, repetitive titrations.
2. Why is DURAN® glass preferred for burettes?
DURAN® is a high-quality borosilicate glass that offers excellent thermal resistance and very high resistance to chemical attack, which is essential for maintaining accuracy over time when using aggressive titrants.
3. Do I need a PTFE or a glass stopcock?
PTFE stopcocks are generally preferred for most modern labs because they do not require grease, which can contaminate the titrant, and they will not freeze or seize if alkaline solutions are left in the burette.
4. What does "Class A" mean for a burette?
Class A (or AS) signifies that the burette has been manufactured to the highest accuracy standards defined by ISO or DIN, with the smallest possible error tolerances, often including a batch certificate.
