-
Excellent chemical resistance (especially to corrosive reagents)
-
Precision in design and dimensions for volumetric accuracy
-
Dimensional stability over repeated use and cleaning
-
Proper sealing (for bottles, vials) and compatibility with caps/closures
As the original blog states:
“The company’s laboratory glassware is renowned for its precision and reliability … made from high-quality borosilicate glass that is resistant to thermal shock.” ASIS Scientific

Material & Technical Considerations
Borosilicate Glass (3.3)
-
Composed of silica (SiO₂), boric oxide (B₂O₃) and alkali/alkaline earth oxides in strict specification. ASIS Scientific
-
Engineered for low thermal expansion, high chemical resistance. Ideal for labs. ASIS Scientific
-
The blog clarifies:
“Borosilicate glass 3.3 … unique combination results in glass that is resistant to chemical attack, making it ideal for processes that involve corrosive products.” ASIS Scientific
Glass Types: Type I vs Type II vs Type III
-
Type I: High-quality borosilicate (the top tier)
-
Type II: Lower resilience to temperature/chemical stress; less ideal for demanding lab work. ASIS Scientific
-
Type III / soda-lime: Common in consumer glassware, not recommended for serious lab use.
Other Considerations
-
Thermal shock resistance: If you rapidly heat or cool glassware, choose the premium borosilicate.
-
Chemical compatibility: Especially relevant for acids, bases, solvents. Lower-grade glass may degrade.
-
Dimensional accuracy: Volumetric flasks/test tubes need tight tolerances for reproducibility.
-
Cleaning, wear & damage: Chips, scratches compromise strength and safety. Inspect regularly.
-
Seals & closures: Bottles/vials need caps that resist corrosion and provide inert atmosphere where needed.
Comparison: Cheap generic glassware vs SCHOTT / DURAN premium glassware
| Feature | Cheap / Generic (value glassware) | SCHOTT / DURAN (premium borosilicate 3.3) |
|---|---|---|
| Typical material | Soda-lime or lower-grade borosilicate (varies). | Borosilicate glass 3.3 (Type I) — engineered to ISO/DIN standards. |
| Price (typical) | Lower unit price; good for disposables or low-risk uses. Example: ValueWare product lines often sold as low-cost options. | Higher unit cost (premium manufacturing, batch QA, traceability). Contact supplier (ASIS) for quotes — long-term value often higher due to lifetime. |
| Durability & breakage resistance | Lower mechanical / abrasion resistance; more prone to chips and scratches over repeated use. | High chemical & scratch resistance; manufactured to tight tolerances and batch QA (DURAN® claims improved scratch & hydrolytic resistance). |
| Thermal shock resistance | Lower — may fail under rapid temperature change depending on material and thickness. | High — DURAN® borosilicate 3.3 has low coefficient of thermal expansion and high thermal shock resistance (ΔT up to ~100 K for many geometries). |
| Lifespan / total cost of ownership | Shorter useful life for high-use lab settings; may be cost-effective for low-risk or disposable workflows. | Longer lifespan under lab conditions, lower replacement frequency, traceability / batch certificates for regulated work (better total cost for high-use / critical tasks). |
| Standards & QA | Varies; cheaper lines may not include batch certificates or tight ISO traceability. | Manufactured to ISO/DIN/ASTM standards with batch documentation available (DURAN® / DWK). |

How to Select and Maintain Your Glassware
Here’s a recommended checklist and best practice guidance:
Selection Checklist
-
Define the application: heating, cooling, storage, mixing, measuring.
-
Choose the correct glass material (prefer borosilicate for demanding use).
-
Verify brand and supply chain (e.g., SCHOTT DURAN via ASIS).
-
Select appropriate size, graduation markings and compatible accessories.
-
Ensure caps/closures match the use environment (chemical resistance, seal integrity).
-
Review budget and supplier support (local stock, after-sales service).
Maintenance & Use Tips
-
Inspect glassware before each use: check for chips, cracks, scratches.
-
Avoid extreme thermal shocks (e.g., hot to cold rapidly) unless rated for it.
-
Clean properly after each use, and avoid abrasive cleaners that may weaken glass.
-
Store appropriately; consider protective sleeves or coatings if applicable.
-
Train users on proper handling, decanting, mixing and labeling.
-
Keep records for critical pieces (especially volumetric or high-precision items).
Case Studies — Real labs improving outcomes with premium glassware
UGA Biopharma — DURAN® culture flasks case study
DWK Life Sciences describes a case where UGA Biopharma evaluated DURAN® culture and baffled flasks. The transition to premium glass flasks delivered consistent performance for precultures and helped the lab meet quality and sustainability goals.
Protective coatings & reducing breakage — Nycote case study
Application of protective coatings (e.g., polymer coatings) to lab glassware is used by some labs to reduce hazards from breakage and extend working life; Nycote publishes case material showing safer handling and fewer incidents after coating.
For pharmaceutical manufacturing environments, peer-reviewed articles also document vial breakage during aggressive processes (e.g., lyophilization) and mitigation strategies — useful background reading.

Frequently Asked Questions
FAQ — Common questions about lab glassware
Q: Can I use soda-lime glass for my lab?
A: It depends on the application. Soda-lime glass is cheaper and can be suitable for low-risk, non-critical tasks. However, for heating, aggressive chemicals, or where reproducibility/chemical resistance matters, borosilicate 3.3 (Type I) like SCHOTT DURAN® is strongly recommended because of its superior chemical resistance and thermal shock performance.
Q: How long should lab glassware last?
A: Lifespan depends on usage, cleaning, and handling. Premium borosilicate glassware (DURAN®, DWK, Kimble) often lasts many years under normal lab use; cheaper glassware may show wear faster. Regular inspection, gentle cleaning and avoiding thermal shock greatly extend lifetime. For critical volumetric glassware, follow calibration/verification schedules per your lab QA plan.
Q: What happens if my glassware chips?
A: Chips significantly weaken glass items and can create contamination hazards. For safety and accuracy, discard or retire chipped glassware (especially volumetric pieces). If chips occur frequently, investigate causes (improper handling, incompatible cleaning or thermal shock) and consider upgrading to higher-quality glass or coated/protected bottles.
