Frequently Asked Questions
1. What is the advantage of a cylinder with a knob lid?
The knob lid on DWK Duran cylinders provides an ergonomic and secure way to seal the vessel, protecting contents from contamination while allowing for easy manual access.
2. Are these cylinders graduated for measurement?
The DWK Duran cylinders in this category are primarily designed for containment and specimen storage and do not feature graduations; for volumetric tasks, please refer to our measuring cylinders category.
3. Can these glass cylinders be autoclaved?
Yes, because they are manufactured from high-quality borosilicate glass, these DWK Duran cylinders and lids are fully autoclavable and resistant to thermal shock.
4. What is a specimen jar used for?
DWK Duran specimen jars are high-clarity glass vessels used for the long-term display or preservation of biological samples, often filled with preservative fluids like ethanol or formalin.
