These OMSONS clear Class A volumetric flasks come with a batch certificate and a glass stopper. They're the brand's highest-precision glassware, used in analytical labs where traceability and very high accuracy matter. They comply with DIN/ISO 1042 and are often calibrated on fully automatic machines to remove human error.

Key Features

  • Accuracy grade: Class A (highest precision).
  • Standard: DIN/ISO 1042.
  • Material: Quality borosilicate 3.3 glass (low expansion, chemical resistant).
  • Stopper: Supplied with an interchangeable ground glass stopper for a vacuum-tight seal.
  • Calibration: Typically calibrated at 27°C (the standard in India and Asia) or 20°C (the European standard).
  • Printing: High-contrast blue enamel markings (acid and scratch-resistant).

Certification Details

  • Batch certificate: Unlike an individual certificate (which covers one specific flask), a batch certificate records the mean value, standard deviation and issue date for the whole production batch.
  • QR code access: Many newer OMSONS Class A flasks have a QR code on the glass, so you can download the certificate on your phone.

Tolerance Table (ISO 1042 Class A)

Capacity (ml) Tolerance (± ml) Neck Size (NS)
10 ml 0.025 10/19
25 ml 0.040 10/19
50 ml 0.060 12/21
100 ml 0.100 14/23
250 ml 0.150 14/23
500 ml 0.250 19/26
1000 ml 0.400 24/29

Primary Applications

  • Preparing standard solutions: Making solutions of an exact known concentration (such as molar solutions), the basis for further chemical testing.
  • Analytical titrations: Preparing titrants or samples for volumetric analysis, where even a 0.1% volume error can invalidate the result.
  • Quantitative dilutions: Accurately diluting a concentrated stock solution to a lower concentration for experiments.
  • Instrument calibration: Preparing the precise standards that instruments like spectrophotometers rely on for a calibration curve.

Sector-Specific Uses

  • Pharmaceutical testing: Checking the dosage and formulation of medicines, where strict standards (like USP or BP) apply.
  • Audits and compliance: The batch certificate (often available via a QR code on the flask) provides documentation for ISO/IEC 17025 audits, showing the glassware meets international accuracy standards.
  • Environmental analysis: Preparing samples for trace analysis of pollutants in water or soil, where accurate volumes are essential.
  • Research and development: Making up new compounds where precise molar ratios decide whether a reaction succeeds.

Why Use a Batch Certificate?

Compared with standard Class B flasks, a Class A flask with a certificate gives traceability back to production. If you get an unexpected result, the certificate lets you rule out the glassware's tolerance as the cause.
