Burets: Essential Tools for Precision Liquid Measurement


Burets are indispensable instruments in laboratories, offering precise liquid measurement for various applications. Whether you're in chemistry, pharmaceuticals, or environmental testing, understanding the types, features, and selection criteria of burets can significantly enhance your workflow. This guide provides actionable insights to help you make informed decisions.


How to Find Reliable Burets from China in 2025


China remains a leading manufacturer of high-quality burets, offering competitive pricing without compromising precision. To find reliable suppliers:

  • Check certifications like ISO 9001 or CE marks.
  • Read customer reviews on platforms like Alibaba or Made-in-China.
  • Request product samples to verify quality.
  • Compare lead times and after-sales support.

What Buyers Should Know Before Buying Burets from China


Purchasing burets from China requires due diligence. Key considerations include:

  • Material: Borosilicate glass is preferred for durability and chemical resistance.
  • Calibration: Ensure the buret meets international standards (e.g., ASTM E287).
  • MOQ: Some suppliers enforce minimum order quantities; negotiate if needed.
  • Shipping: Factor in logistics costs and potential delays.

Types of Burets


Burets come in several designs, each suited for specific tasks:

  • Digital Burets: Offer automated dispensing with high accuracy (±0.1%).
  • Glass Burets: Traditional and cost-effective, ideal for manual titrations.
  • Automatic Burets: Reduce human error with motorized controls.
  • Micro Burets: Designed for small-volume measurements (0.01 mL increments).

Functions and Features of Burets


Modern burets include features that enhance usability:

  • Precision Stopcocks: Enable smooth liquid flow control.
  • PTFE Teflon Tips: Resist chemical corrosion.
  • Ergonomic Designs: Reduce hand fatigue during prolonged use.
  • Self-Cleaning Mechanisms: Minimize cross-contamination.

Scenarios of Burets


Burets are widely used in:

  • Academic Labs: For teaching titration techniques.
  • Pharmaceuticals: Precise drug formulation measurements.
  • Environmental Testing: Analyzing water or soil samples.
  • Food Industry: Quality control for acidity or alkalinity tests.

How to Choose Burets


Selecting the right buret depends on:

  • Volume Range: Match the buret’s capacity to your typical sample sizes.
  • Accuracy Needs: Digital models excel for high-precision tasks.
  • Budget: Glass burets are affordable, while digital ones offer advanced features.
  • Brand Reputation: Opt for established manufacturers like BrandTech or Kimble.

Burets Q & A


Q: How often should burets be calibrated?
A: Calibrate every 6 months or after 500 uses, whichever comes first.


Q: Can burets measure viscous liquids?
A: Yes, but opt for models with wider bores to prevent clogging.


Q: What’s the lifespan of a glass buret?
A: With proper care, 3–5 years; avoid sudden temperature changes.


Q: Are Chinese burets as accurate as German ones?
A: Reputable Chinese suppliers meet the same ASTM standards at lower costs.


Q: How to clean a buret effectively?
A: Rinse with distilled water followed by acetone, then air-dry upside down.
