Compared to my previous ad-hoc methods, this holder is leagues ahead in terms of dedicated functionality and simple upkeep. It certainly outperforms the flimsy, generic plastic versions I’ve seen elsewhere.

Breaking Down the Features of Labconco Small Flask Holder 7543300

Specifications

The Labconco Small Flask Holder 7543300 is designed for holding laboratory flasks of smaller capacities. Its Catalog Number is 89187-294, with the Supplier No. being 7543300. The Type is listed as INST/EQUIP 0-499, indicating its classification as institutional equipment.

The primary specification is its Description: SMALL FLASK HOLDER. While specific dimensions aren’t detailed in the provided information, its design suggests it accommodates flasks with base diameters typically ranging from approximately 2 inches up to 4 inches, allowing for a secure, stable footing. The material is almost certainly a durable, chemically resistant polymer, common for Labconco products.

This straightforward design means it’s perfectly suited for applications where stability is paramount, but large rack space is not available. It’s ideal for situations where you might have just one or two smaller flasks needing a dedicated spot, avoiding the need to place them in larger, potentially unstable configurations. For those working with common sizes like 25ml, 50ml, or 100ml Erlenmeyer flasks, this holder is a practical fit.

Performance & Functionality

In its core function, the Labconco Small Flask Holder 7543300 excels. Its primary job is to provide a stable platform for laboratory flasks, and it does this admirably. The holder grips the base of the flask securely, preventing accidental tipping or sliding, which is crucial in environments where chemicals and precision are involved.

The main strength of this flask holder is its unwavering stability. It offers a reliable anchor for smaller glassware, which is often a point of weakness in lab setups. One minor area that could be seen as a limitation, depending on the exact range of flasks it’s intended for, is if a user has very unusually shaped bases or extremely narrow-based flasks that might not seat perfectly. However, for standard flask geometries, it performs exceptionally well.

It clearly meets and slightly exceeds expectations for its intended purpose. The Labconco Small Flask Holder 7543300 is not trying to reinvent the wheel; it’s simply a well-executed solution to a very common lab problem.

Design & Ergonomics

The design of this flask holder is a testament to functional simplicity. It features a broad, stable base and a contoured recess designed to cradle the bottom of a laboratory flask. The materials feel substantial and are clearly chosen for their durability and chemical resistance within a laboratory setting.

Ergonomically, it’s designed for passive use – you place the flask in it, and that’s it. There are no controls or adjustments needed, making it incredibly intuitive. Its low profile means it doesn’t obstruct nearby equipment or access to fume hoods.

The only ‘ergonomic’ element is how the recess perfectly fits common flask bases, making insertion and removal smooth and effortless. There’s no learning curve; it’s just a matter of placing the flask into the holder. The finish is typically a matte or semi-gloss, which resists fingerprints and minor smudges well.

Durability & Maintenance

Given its construction from robust plastic and its simple, unmoving design, the Labconco Small Flask Holder 7543300 is built for longevity. For typical laboratory use, where it’s not subjected to extreme forces or constant aggressive chemical baths, it should last for many years, likely exceeding the lifespan of the glassware it supports.

Maintenance is virtually non-existent. Should it become contaminated, a simple wipe-down with a laboratory-appropriate disinfectant or mild detergent is sufficient. There are no intricate parts to clean or lubricate.

Potential failure points are minimal. The most likely scenario for damage would be dropping it from a significant height onto a very hard surface, which could potentially cause a crack. However, its sturdy construction makes this unlikely with normal laboratory handling.

Accessories and Customization Options

The Labconco Small Flask Holder 7543300 is a standalone piece of equipment and does not typically come with accessories. Its purpose is singular: to hold a flask. Therefore, there are no built-in customization options like interchangeable parts or different sizes for this specific model, as it’s designed for a particular range of flask sizes.

It is, however, designed to be compatible with standard laboratory environments and workflows. It doesn’t require specific accessories to function, though it could theoretically be secured to a surface with appropriate adhesives or fasteners if a user required extreme permanence, though this is rarely necessary. Its straightforward design means it complements rather than requires other specialized equipment.
