Burette 100ml – Automatic Class A (BOROSIL®)

Burette 100mL – Automatic Class A (BOROSIL®) is a high-performance laboratory instrument designed for the controlled and accurate delivery of larger liquid volumes, typically in the 0-100mL range. It combines automatic operation for ease of use with exceptional accuracy and chemical resistance, making it a valuable tool for various laboratory tasks.

Core Features:

• Automatic Operation: This is a defining feature. Unlike traditional burettes with a stopcock, this model boasts an automatic dispensing mechanism for effortless control:

  • Motorized: A small motor within the burette precisely regulates the flow rate, enabling smooth and consistent dispensing.
  • Squeeze Bottle Design: Some models might utilize a squeezable bottle reservoir. Squeezing the bottle pressurizes the liquid, forcing it out through a calibrated valve at a controlled rate.

• High Accuracy (Class A): This burette meets Class A specifications as defined by international standards (often ISO 385). This signifies exceptional accuracy in its graduations and overall volume measurements. Deviations from the marked volume will be minimal, ensuring highly precise liquid delivery for critical experiments.

• BOROSIL® Glass Construction: The burette is crafted from BOROSIL® glass, a type of borosilicate glass known for:

  • Chemical Resistance: BOROSIL® glass is resistant to a wide range of chemicals commonly used in laboratories, minimizing the risk of the burette reacting with the solutions it dispenses.
  • Thermal Stability: This glass can withstand high temperatures, making it suitable for use with hot or cold liquids.
  • Clarity: BOROSIL® glass offers excellent clarity for easy visualization of the liquid level within the burette.

• Capacity: 100 Milliliters (mL):** This increased capacity caters to a broader range of applications compared to smaller models, allowing for dispensing volumes up to 100mL. This is ideal for handling larger samples or experiments requiring significant liquid volumes.

• Calibration: While Class A specifications ensure high accuracy, some automatic burettes might require periodic calibration to maintain optimal performance. Consult the manufacturer’s instructions for details on calibration procedures or recommended intervals.

Applications:

• Large Volume Titrations: The automatic dispensing and high accuracy make this burette well-suited for titrations involving larger sample volumes (up to 100mL). Titration is a common technique where a standardized solution (titrant) is gradually added to another solution (analyte) to determine its concentration.
• Dispensing Measured Volumes (Large Quantities): This burette is a valuable tool for applications requiring controlled delivery of larger liquid volumes (up to 100mL) with high precision. This could involve preparing large volume dilutions, adding reagents to experiments, or performing sample injections in analytical techniques that utilize larger sample sizes.

Benefits of Automatic Operation:

• Effortless Dispensing: The automatic mechanism simplifies the dispensing process, reducing user fatigue and potential errors associated with manual stopcock control, especially when dealing with larger volumes.
• Improved Consistency: Automatic burettes deliver a more consistent flow rate compared to manual techniques, leading to more reproducible results in experiments, even when dispensing larger volumes.
• Enhanced Safety: Automatic dispensing can minimize the risk of spills or splashes associated with manual burette operation, particularly when handling larger volumes.
