Description
Precision is the foundation of every successful analytical titration. Therefore, Osmosis Scientific provides this Class AS Burette with an advanced PTFE needle valve. First, this stopcock design eliminates the need for manual lubrication. Consequently, your samples remain pure and free from grease contamination. Furthermore, the needle valve allows for exceptionally smooth flow. This enables you to achieve the exact endpoint with drop-by-drop sensitivity.
We manufacture these instruments from high-quality Boro 3.3 borosilicate glass. This material withstands thermal shock and aggressive chemical reagents effectively. Additionally, the Class AS calibration ensures the highest level of accuracy for professional research. Whether you utilize the 10ml size for micro-analysis or the 100ml size for industrial testing, the accuracy remains consistent.
If your facility requires strict traceability, we recommend the serialized option. We laser-etch a unique serial number on each individual burette to match its Work Certificate. Finally, the durable amber enamel markings resist fading even after repeated sterilization. This makes our burettes a long-lasting solution for precision liquid handling.
Note: For outsourced or certified products, Osmosis Scientific acts as a supplier and distributor. Certification validity, calibration accuracy, and traceability are the responsibility of the original manufacturer or issuing certification body. Osmosis Scientific shall not be held liable for calibration deviations caused by improper handling, physical damage, wear, or chemical exposure after delivery.

Frequently Asked Questions (FAQs)
All Osmosis Scientific burettes are produced using High-quality Borosilicate 3.3 glass. This ensures:
- Superior resistance to chemical attack (acids and alkalis).
- Excellent thermal shock resistance.
- High transparency for easy monitoring of the liquid level.
Since no grease is used, cleaning is simple. The needle valve can be unscrewed from the glass housing and rinsed with distilled water or a suitable solvent. Ensure the fine tip of the needle is free of any particulate matter to maintain smooth flow control.
These instruments are designed and quality-controlled to comply with international metrology standards such as ISO 385 and DIN 12700.
