Class A Individually Certified Volumetric Flask with Glass Stopper
Manufacturer: United Scientific
For laboratories operating under the strictest quality management systems, such as ISO 17025, GLP, or GMP, the United Scientific Individually Certified Volumetric Flasks offer the highest level of documentation and precision. Unlike batch-certified glassware, each of these flasks is individually serialized and comes with its own unique certificate of calibration. Each flask features a durable, machine-blown borosilicate body and a heavy beaded tubing neck for superior mechanical strength. Calibrated "To Contain" (TC) at 20C, they meet all ASTM E-288 Class A specifications. The sharp, permanent graduation line and high-contrast white block lettering ensure error-free readings for your most critical standard preparations.

Key Functional Benefits:
- Individual Accountability: Serialization allows for precise tracking of specific glassware in an asset management system, essential for root-cause analysis in out-of-specification (OOS) investigations.
- Premium Construction: Machine-blown bodies ensure uniform wall thickness, while the heavy-duty neck bead minimizes the risk of breakage during stopper insertion or removal.
- Superior Chemical Integrity: Borosilicate glass provides high resistance to chemical attack, preventing leachable contaminants from affecting your analytical samples.
- Permanent Traceability: The serial number and graduation marks are fused into the glass, ensuring they remain legible even after years of use and cleaning.
Maintenance & Audit Preparedness:
- Documentation Management: Keep the individual certificate provided with each flask in your laboratory’s equipment binder. Auditors will often verify that the serial number on the glass matches the physical certificate on file.
- Meniscus Technique: To maintain the certified accuracy, ensure the liquid is at thermal equilibrium (20°C). For aqueous solutions, the lowest point of the meniscus must be perfectly tangent to the graduation line when viewed at eye level.
- Avoiding Abrasions: Use only soft-bristle brushes or non-abrasive cleaning systems. Scratches on the interior neck can obscure the graduation line or cause "clinging" drops that affect volume accuracy.
