At Labend Scientific, our Complete Flask Inventory features high-resistance Borosilicate 3.3 glass that ensures chemical inertness and stability. From the iconic Borosil Conical Flask 5340 (Erlenmeyer) to specialized round-bottom variants, our products meet stringent ISO 1773 and 4797 standards. In thermal separation workflows, such as distillation, the Borosil Distillation Flask 4385 and the Boiling Flask 5019 provide uniform wall thickness for even heat distribution. For high-precision standard solution preparation, researchers rely on the Borosil Volumetric Flask 2020, often used in conjunction with Borosil Pipettes for micro-volume liquid handling. Our flasks are frequently integrated into complex assemblies, including vacuum filtration setups using the ESAW Filter Holder. For specialized organic chemistry applications like nitrogen determination, the Borosil Kjeldahl Flask 4620 is the industry benchmark. Whether you are storing reagents in a Borosil Bottle or incubating cultures for monitoring in ESAW Petri Dishes, Labend Scientific guarantees glassware that withstands aggressive reagents and extreme temperature gradients. Flask Utilization FAQ Q1: What makes Erlenmeyer flasks ideal for titration? A: Their conical shape and narrow neck allow for vigorous swirling and mixing of liquids without the risk of spillage during the titration process. Q2: Can Volumetric Flasks be heated directly? A: No. Heating volumetric flasks can cause thermal expansion that permanently alters their calibrated volume accuracy. Q3: Why is a Kjeldahl Flask shaped differently? A: The long neck prevents acid splashes and minimizes evaporation losses during intense nitrogen digestion processes. Q4: What are the primary SEO keywords for flasks? A: Borosil Flask Price India, Glass Erlenmeyer Flask 250ml, Volumetric Flask Class A, Boiling Flask Round Bottom, Labend Scientific Glass Catalog.
