DURAN 218032451 Erlenmeyer Flask with Screw Cap 100 mL

DURAN 218032451 Erlenmeyer Flask with Screw Cap 100 mL

The DURAN 218032451 is a 100 mL Erlenmeyer flask made from high-quality DURAN® borosilicate glass (Glass Type I / neutral glass). It features a DIN screw thread neck fitted with a PBT (polybutylene terephthalate) screw cap, which is autoclavable up to ~180 °C. Graduated markings (approximate) are printed on the flask to allow volume estimation. The flask is suitable for storage, cultivation, or general laboratory tasks where container closure is needed.

Key design features include:

• Neck Type & Cap: DIN screw neck (GL25 thread) with PBT screw cap — tight closure, good for storage or preventing contamination.

• Capacity & Dimensions: Nominal 100 mL capacity; bottom diameter ~ 64 mm; height ~ 109 mm.

• Material: DURAN® borosilicate glass 3.3 — excellent chemical resistance and thermal stability.

• Graduations: Approximate markings (not precision volumetric), allowing reasonable estimation of liquid volumes.

• Retrace/Batches & Certification: Includes retrace (batch identification) code for traceability; certificate available online. Meets standards consistent with USP/EP/JP for Type I glassware.

• Autoclaving: Yes — flask and screw cap are autoclavable (remove or loosen cap prior to autoclaving) up to specified temperature (cap up to ~180 °C).

Key Specifications

Applications & Use Cases

• Good for storage or culture, where sealing is helpful (e.g. preventing contamination or spillage).

• Suitable for lab settings needing a flask + closure system (e.g. reagent prep, small fermentations, microbial cultures).

• Useful where approximate volume readings suffice — e.g. buffer prep, sample dilutions.

• When using autoclave, loosen cap to avoid pressure build-up.

Limitations & Handling Notes

• Graduations are approximate only — not for analytical-grade volumetric work.

• Though the screw cap is autoclavable up to ~180 °C, sealing too tightly or leaving liquid inside with cap closed during sterilization may cause pressure issues.

• Glass remains fragile — avoid mechanical shock; also avoid rapid temperature changes.
