Description
Fernbach-type culture flask 1800 ml is a conical borosilicate glass vessel designed for microbial and cell culture work that benefits from a wide base and generous headspace. With a nominal volume of 1,8 l and overall dimensions of 200 × 175 mm, the flask provides a large liquid surface area that supports efficient gas exchange during shaking or static incubation. The straight neck has an outer diameter of 38 mm and is intended for use with metal caps, enabling secure closure while remaining compatible with common laboratory closures. Manufactured from DURAN tubing in borosilicate glass 3.3, the vessel offers the thermal and chemical resistance expected of high-quality laboratory glassware. Supplied as a pack of 2 pieces from manufacturer Witeg, each flask has a net weight of 0,57 kg. Typical applications include bacterial and fungal shake cultures, media preparation, and scale-up steps in tissue and cell culture workflows where the classic Fernbach geometry improves aeration compared with standard Erlenmeyer flasks. The clear glass body allows easy visual monitoring of culture progress throughout incubation.

Questions about Culture flasks, FERNBACH type, 1800 ml,
What is this article?
Culture flasks, FERNBACH type, 1800 ml, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Cell culture flasks, inside Cell culture, in Microbiology lab supplies.
A culture flask is a flat vessel with a cap, treated so adherent cells attach, or untreated for suspension cells. Growth area in square centimetres, the cap filter or a plug seal, and the treatment are the specification. A filter cap allows gas exchange. A plug seal does not.
Cell culture grows cells outside the body. The medium, often with serum, supplies what the flask does not. A flask or a dish is the vessel, treated so the cells attach or left untreated so they float. Contamination by microbes, or by another cell line, is the ordinary failure. Cold-chain articles in this work, including serum, are never part of free standard delivery. Lines are catalogued by ATCC. Papers are on PubMed. Practice is summarised by the WHO laboratory biosafety topic.
