ISI Standard Specifications
Dimensional tolerances and wall thickness specifications for our high-capacity Borosilicate 3.3 beakers and conical flasks, manufactured for Indian and global laboratories.
Borosilicate Beakers (ISI Dimensions)
Our heavy-duty, high-capacity laboratory beakers (2000 mL to 5000 mL) are crafted from premium Borosilicate 3.3 glass. They are designed to meet strict ISI physical dimensions for external diameter, height, and wall thickness to ensure exceptional thermal shock resistance and durability during intensive laboratory heating applications.
| Capacity | External Diameter | Overall Height (Max.) | Wall Thickness ±5 |
|---|---|---|---|
| 2000 mL | 130 mm ±5% | 185 mm ±3% | 3 mm |
| 3000 mL | 150 mm ±5% | 214 mm | 2.8 mm |
| 5000 mL | 170 mm ±5% | 274 mm | 3.5 mm |
Erlenmeyer Conical Flasks (ISI Dimensions)
Ideal for mixing, heating, and storing large volumes of liquids. These high-capacity conical flasks are manufactured with a minimum wall thickness of 3.5 mm, providing superior mechanical strength for industrial testing, pharmaceutical preparation, and institutional research.
| Capacity | Body OD at Widest Point | Neck OD | Overall Height | Minimum Wall Thickness (± 0.5) |
|---|---|---|---|---|
| 2000 mL | 166 ± 3 mm | 50 ± 2 mm | 280 ± 4 mm | 3.5 mm |
| 3000 mL | 187 ± 3 mm | 50 ± 2 mm | 310 ± 5 mm | 3.5 mm |
| 5000 mL | 220 ± 3 mm | 50 ± 2 mm | 365 ± 5 mm | 3.5 mm |
