Burette 50ml – Automatic Class A (BOROSIL®)

Burette 50mL – Automatic Class A (BOROSIL®) is a high-precision instrument designed for the controlled and accurate delivery of liquid volumes, particularly in the 0-50mL range. This burette incorporates automation for effortless operation alongside exceptional accuracy and chemical resistance. Here’s a breakdown of its key features and functionalities:

Core Features:

• Automatic Operation: This is a defining characteristic. Unlike traditional burettes with a stopcock, this burette features 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: 50 Milliliters (mL):** This burette’s increased capacity caters to a wider range of applications compared to smaller models, allowing for dispensing volumes up to 50mL.

• 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:

• Titrations (Larger Samples): The automatic dispensing and high accuracy make this burette ideal for titrations involving larger sample volumes (up to 50mL). Titration is a common technique where a standardized solution (titrant) is gradually added to another solution (analyte) to determine its concentration.
• Dispensing Measured Volumes (Larger Quantities): For applications requiring the controlled delivery of larger liquid volumes (up to 50mL) with high precision, this burette is a valuable tool. This could involve preparing dilutions, adding reagents to experiments, or performing sample injections in analytical techniques.

Benefits of Automatic Operation:

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