Flask Stand

This versatile flask stand is designed to accommodate a comprehensive range of round bottom flask sizes, from small 50 ml flasks used in routine synthesis up to large preparative vessels of 10 liters capacity. The stair-step design features multiple graduated steps that correspond to the curvature of different flask sizes, ensuring proper support regardless of flask dimensions. For smaller flasks, the upper, smaller-diameter steps provide the primary support, while larger flasks are cradled by the lower, larger-diameter steps. This universal design means a single stand can serve multiple flask sizes, reducing the need for multiple dedicated stands and saving valuable laboratory storage space. The stands robust polypropylene construction ensures it can safely support the weight of even the largest 10-liter flasks when fully filled.

Yes, this Polylab Flask Stand is fully autoclavable and designed to withstand repeated steam sterilization cycles. Manufactured from high-quality polypropylene, it can be safely autoclaved at standard cycles of 121°C (250°F) at 15 psi for 20 minutes. The material maintains its structural integrity and dimensional stability through multiple sterilization cycles, making it ideal for use in sterile environments such as microbiology labs, cell culture facilities, and pharmaceutical manufacturing areas. For proper sterilization, simply place the clean flask stand in the autoclave using standard loading procedures. There is no need to disassemble or prepare the stand in any special way. After the cycle completes, allow the stand to cool before handling. The corrosion-proof nature of polypropylene ensures that autoclaving will not cause rust or degradation, unlike metal stands that may deteriorate with repeated sterilization.

The stackable design of these flask stands offers significant advantages for laboratory storage and organization. When multiple stands are not in active use, they can be nested together vertically, occupying a fraction of the space required by non-stackable designs. This space-saving feature is particularly valuable in crowded laboratories where bench and cabinet space is at a premium. The stands stack securely without tipping, allowing for neat, organized storage that keeps them readily accessible when needed. The stackable design also facilitates inventory management and transport—multiple stands can be moved as a single unit, saving time and effort during laboratory reorganization or when setting up multiple workstations. This thoughtful design feature demonstrates Polylabs commitment to creating products that not only perform excellently but also enhance overall laboratory efficiency and organization.

The Polylab Flask Stand (Code 45105) features carefully engineered dimensions to accommodate a wide range of flask sizes while maintaining stability. The stand has an approximate base diameter of 200 mm and a height of 80 mm, with the stair-step design featuring graduated step diameters from approximately 50 mm at the top to 180 mm at the base. These dimensions allow it to securely support round bottom flasks from 50 ml up to 10 liters capacity. The stand itself weighs approximately 150 grams, making it lightweight and easy to handle. In terms of weight capacity, the robust polypropylene construction can safely support fully filled 10-liter flasks, which can weigh over 10 kg when containing dense solutions.

Polypropylene, the material used in this flask stand, offers excellent resistance to a wide range of laboratory chemicals. It is resistant to most dilute and concentrated acids (with the exception of strong oxidizing acids like concentrated sulfuric and nitric), dilute and concentrated bases, alcohols, aldehydes, esters, ketones, and most aqueous solutions. This broad chemical resistance ensures that accidental spills of common laboratory reagents will not damage or degrade the stand. However, polypropylene can be attacked by some organic solvents including aromatic hydrocarbons (toluene, xylene), chlorinated solvents (chloroform, dichloromethane), and some hydrocarbons. For applications involving aggressive chemicals or solvents, we recommend consulting our comprehensive chemical resistance chart or contacting our technical support team for specific compatibility guidance. The materials inherent chemical resistance, combined with its corrosion-proof nature, ensures that this flask stand will maintain its appearance and structural integrity even in demanding laboratory environments.

While this flask stand is specifically optimized for round bottom flasks, its versatile stair-step design can also accommodate other spherical or curved laboratory glassware. Items such as boiling flasks, pear-shaped flasks, and some types of reaction vessels with curved bottoms may also be securely supported. The stand may also serve as a general-purpose stable platform for various laboratory containers. However, for optimal safety and performance, we recommend using the stand primarily for its intended purpose of supporting round bottom flasks. When using with other glassware, always ensure that the item is stable, properly seated in the stand, and that the support provided is adequate to prevent tipping or accidents. For specialized glassware with unusual shapes or dimensions, alternative support solutions may be more appropriate.

Maintenance of this polypropylene flask stand is simple and straightforward, requiring minimal effort to keep it in optimal condition. For routine cleaning, wash the stand with mild laboratory detergent and warm water, using a soft brush or sponge to remove any residues. Rinse thoroughly with tap water followed by a final rinse with distilled or deionized water, then allow to air dry or wipe with a clean lab cloth. For removal of stubborn chemical residues, the stand can be soaked in appropriate cleaning solutions compatible with polypropylene. For sterile applications, simply autoclave the clean stand using standard cycles. The corrosion-proof nature of polypropylene means you never need to worry about rust or degradation from moisture. Avoid using abrasive cleaners or scrubbers that could scratch the surface. With this simple care regimen, your Polylab Flask Stand will provide decades of reliable, maintenance-free service in your laboratory.
