Breaking Down the Features of Kimble/Kontes KIMAX Volumetric Flasks with ST Glass Stopper, Class A, Serialized and Certified, Kimble Chase 28017 1000
Specifications
-
Capacity: 1000 mL. This is the volume the flask is calibrated to contain at a specific temperature, allowing for large-scale reagent preparation.
-
Tolerance: ± 0.30 mL. This narrow tolerance band is indicative of a Class A volumetric flask, which ensures high accuracy in quantitative analyses.
-
ST Stop. No.: 22. The ST (Standard Taper) stopper number indicates the size and taper of the glass stopper, ensuring a tight, leak-proof fit.
-
Material: Borosilicate Glass. The flask’s construction using borosilicate glass ensures high resistance to chemical corrosion and thermal shock.
-
Class A Certification. This certification guarantees that the flask meets strict accuracy standards, making it suitable for critical laboratory applications.
These specifications matter greatly for applications demanding accuracy. The borosilicate glass also means the flask can withstand the rigors of daily use without degradation.
Performance & Functionality
The Kimble/Kontes KIMAX Volumetric Flask excels at its primary function: delivering accurate volumes of liquids. The precision ground glass stopper creates a leak-proof seal that preserves sample integrity during mixing and storage.
Its strength is in its guaranteed accuracy and durability. An area for potential improvement could be a more ergonomic design for easier handling, especially when wearing gloves. It meets and exceeds my expectations.
Design & Ergonomics
The KIMAX flask is constructed from high-quality borosilicate glass, giving it a robust feel. The weight is substantial enough to provide stability, but not excessively heavy.
The neck of the flask is narrow for precise meniscus reading, yet wide enough to easily pour reagents. There is a small learning curve involved in correctly reading the meniscus, but this is standard for all volumetric glassware.
Durability & Maintenance
Constructed with thick-walled borosilicate glass, the flask is designed to withstand frequent handling and cleaning. With proper care, the flask should last for many years without any degradation in performance.
Maintenance is relatively simple, requiring only standard laboratory glassware cleaning procedures. It is also important to protect the glass stopper from damage, as a chipped stopper will compromise the seal.
Accessories and Customization Options
The flask comes standard with a precision-ground glass stopper. While there are no formal customization options, the flask is compatible with standard laboratory labeling and marking pens.
The flask can be used with various commercially available stirring devices and heating mantles.
