Breaking Down the Features of VWR Vwr Jar Sh Clr Qal 125ml Cs24 QLFS15900261

Specifications

The VWR Vwr Jar Sh Clr Qal 125ml Cs24 QLFS15900261 comes with several key specifications that are vital for its intended use. Each unit boasts a 125 ml capacity, offering a practical volume for various laboratory tasks. The material is clear glass, which is crucial for visual inspection of contents and ensuring chemical inertness. Each jar is fitted with a screw-on plastic cap, designed to provide a secure and reliable seal. The product is sold in a case of 24 units, making it an economical choice for stocking a lab.

The 125 ml capacity is a significant advantage over smaller 30 ml or 60 ml vials, allowing for the storage of larger reagent batches or more substantial samples without frequent replenishment. The clear glass construction is a fundamental requirement for many analytical procedures where visual confirmation of purity or absence of contaminants is essential; it’s a stark contrast to opaque containers that hide potential issues. The secure plastic cap is designed for repeated use and offers a good balance between ease of opening and leak resistance, which is paramount when handling liquids. Being packaged in a 24-count case means that labs can benefit from bulk purchasing power, reducing the per-unit cost.

Performance & Functionality

The primary job of the VWR Vwr Jar Sh Clr Qal 125ml Cs24 QLFS15900261 is to contain and protect its contents, and in this regard, it performs exceptionally well. The leak-resistant seal provided by the cap is a major strength, preventing evaporation and contamination, which is vital for maintaining the integrity of sensitive reagents and samples. Its functionality extends to easy visual inspection; the high clarity of the glass allows for quick assessment of the sample’s condition without disturbance. There are no real weaknesses to speak of in terms of its core function; it does exactly what it’s designed to do, reliably.

Considering its intended use, this VWR jar exceeds expectations for a standard laboratory container.

The consistent performance across multiple units within the case further solidifies its value.

Design & Ergonomics

The design of these jars is elegantly simple, focusing on practical functionality rather than aesthetic flair. The straight-sided glass body provides a stable base, preventing accidental tipping, and the smooth interior surfaces facilitate thorough cleaning. The plastic screw-on cap is textured for an easy grip, even with gloved hands, and its threading is smooth, allowing for effortless opening and closing.

Ergonomically, the jars are comfortable to hold and manipulate. The 125 ml volume strikes a good balance between substantial capacity and manageable weight, even when full. The clear, prominent volume markings etched or printed on the glass are helpful for quick estimations, although for precise measurements, using calibrated equipment is always recommended.
