Accuracy in Titration and efficiency in filtration are the cornerstones of countless analytical methods. PolyLab's Titeration and Filteration equipment is designed to excel at both. Our burettes are widely considered the top rated by teaching labs for their durability and the smooth action of the stopcocks, which stand up to constant student use. For industrial QC labs processing high sample volumes, our multi-place filtration manifolds offer the best way to streamline workflows without compromising on the quality of the separation. We combine traditional glass craftsmanship with the shatter-resistant benefits of modern polymers where it counts. Elevate your analytical bench with PolyLab and achieve results you can trust, drop by drop and filter by filter. It is the best equipment for wet chemistry and the top rated by analytical professionals.

Frequently Asked Questions Separatory Funnel

PolyLab burettes are available with Class A or Class B accuracy. Class A burettes meet the highest accuracy standards for quantitative analysis and are individually calibrated. Class B burettes are suitable for teaching and general laboratory work where slightly broader tolerances are acceptable.

To prevent bubbles, rinse the burette with titrant before filling. Fill slowly and tap the burette gently to dislodge any bubbles. Open the stopcock fully to flush the tip before starting your titration. PolyLab burettes feature precision tips designed to minimize bubble formation.

PolyLab offers filter membranes in various materials including cellulose acetate (for aqueous), nylon (for general use), PTFE (for solvents), and polyethersulfone (for biologicals). Pore sizes range from 0.2μm for sterilization to 0.45μm for general filtration and larger for particle removal.

Connect a filtration flask to a vacuum source using thick-walled vacuum tubing. Place the filter funnel on the flask with a sealing stopper. Add your filter membrane, wet slightly to seal, and apply vacuum. PolyLab filtration components are designed for leak-free connections.

Many PolyLab filtration components are autoclavable, allowing for sterile filtration setups. Check specific product specifications as some membranes may have temperature limitations. For sterile applications, we also offer pre-sterilized disposable filtration units.

PTFE (Teflon) stopcocks are self-lubricating and operate smoothly without grease. They are chemically inert and resist freezing, making them ideal for titrations with aggressive reagents. PolyLab burettes feature PTFE stopcocks for reliable, maintenance-free performance.
