The combination of borosilicate glass and PTFE materials offers outstanding chemical resistance, making it suitable for use with strong acids, bases, and organic solvents. Its durability and easy sterilization through autoclaving at standard conditions ensure reliable, repeated usage.

Effortless Volume Reading and Calibration

The Schell Bach Stripe integrated into the burette provides a distinct visual aid, allowing for effortless and precise meniscus reading. Graduated calibrations meet ISO 385 and DIN standards, and are available in Class A or B accuracy. The cylindrical, straight shape and white marking area facilitate easy handling and clear labeling during laboratory operations.

FAQs of Burette with Straight Bore PTFE Key stopcock Schell Bach Stripe:

Q: How do I use the straight bore PTFE key stopcock for precise titration?

A: To operate the straight bore PTFE key stopcock, gently rotate the key to control liquid flow, allowing precise dropwise delivery during titrations. The straight bore design ensures consistent, accurate flow control, essential for volumetric analysis.

Q: What is the benefit of the Schell Bach Stripe on this burette?

A: The Schell Bach blue/white stripe enhances meniscus visibility against the solution, making it easier to align the liquids curvature for precise volume readings, thus reducing reading errors during measurements.

Q: When should I choose a Class A burette over Class B?

A: Choose a Class A burette when maximum measurement accuracy is required, such as in analytical chemistry or quality control labs. Class A offers tighter tolerances (typically 0.05mL/25mL) compared to Class B, ensuring more precise results.

Q: Where can I use this burette in laboratory applications?

A: This burette is suitable for titration, preparation of standard solutions, and other volumetric analyses in chemical, biological, and environmental laboratories, especially where high accuracy and chemical durability are essential.

Q: What size options are available and how do I select the right capacity?

A: The burette comes in 10mL, 25mL, 50mL, and 100mL capacities. Select a size that matches your anticipated volume measurementsthe 25mL and 50mL burettes are commonly used for typical titration procedures.

Q: How is this burette resistant to chemicals and heat?

A: Constructed from borosilicate glass and PTFE, the burette resists corrosion by strong acids, bases, and most solvents. The glass component also withstands temperatures up to 200C, allowing use in a variety of chemical protocols and autoclaving for sterilization.

Q: What is the correct process for labeling and storing this burette?

A: Utilize the white marking area on the burette for easy identification with a suitable laboratory marker. After use and cleaning, store it vertically or in appropriate racks to avoid damage and contamination.
