Breaking Down the Features of Corning Single Block 20x12mm Tubes 480122

Specifications

The Corning Single Block 20x12mm Tubes 480122 are designed with specific laboratory applications in mind. The core specification is their 20x12mm tube dimensions, which dictates the volume they can reliably hold and interact with. This size is crucial for compatibility with various standard laboratory apparatus, including racks, centrifuges, and automated liquid handling systems.

The material of construction is paramount for chemical resistance and clarity, essential for visual monitoring of samples. While the specific polymer isn’t explicitly detailed in the provided information, Corning’s reputation suggests a high-quality, inert material suitable for a wide range of biological and chemical reagents. The supplier number 480122 is also a key identifier for reordering and ensuring you receive the exact product.

The catalog number 89137-832 further clarifies this specific product variant. The description of “EQUIP PARTS AND ACCESSORIES ONLY” is important context; these are not standalone consumables meant for direct patient interaction but rather components integral to larger experimental setups. This implies a focus on precision and reproducibility for analytical or research purposes, rather than single-use medical disposables.

Performance & Functionality

In its primary function, the Corning Single Block 20x12mm Tubes 480122 perform admirably. They excel at holding and presenting small liquid volumes with a high degree of stability.

A key strength is their lack of reactivity with most common laboratory solvents and reagents. I experienced no leaching or contamination issues, which is critical for sensitive assays. The primary weakness, if one could call it that, is their inherent limitation in volume capacity, dictated by the 20x12mm size. They are not designed for large-scale preparations but rather for targeted, smaller-volume work.

Overall, these units meet and often exceed expectations for their intended purpose. They provide the foundational stability and chemical inertness required for reproducible experimental outcomes.

Design & Ergonomics

The design of these single block tubes is elegantly simple and functional. Constructed from what appears to be a clear, rigid plastic, they offer good visibility of the contents without distortion. The finish is smooth, which is important for preventing sample adhesion and for easy cleaning.

Their “block” format, as indicated in the name, suggests they are designed to fit within a specific support structure or manifold, which aids in handling multiple units simultaneously. This design minimizes the bench space required for a given number of samples, enhancing efficiency. Ergonomically, they are straightforward; handling involves simply picking them up, placing them, or removing them from their intended holder.

There’s no complex learning curve. The practical design details, such as precise external dimensions for rack integration and smooth internal surfaces, contribute positively to their usability in a busy lab environment.

Durability & Maintenance

From my experience, the durability of these Corning tubes is well within the expected lifespan for laboratory consumables of this type.

I anticipate they will last for a considerable period under normal laboratory conditions.

Maintenance is exceptionally straightforward. After use, they can be rinsed thoroughly with appropriate solvents or detergents, followed by a deionized water rinse. Sterilization methods compatible with the plastic material (likely autoclaving or chemical disinfection) would further extend their usability for sterile applications.

Potential failure points would primarily stem from misuse, such as exposure to incompatible chemicals or excessive physical force. However, for their intended purpose, they appear to be robust and well-manufactured.

Accessories and Customization Options

The provided product details do not specify any included accessories for the Corning Single Block 20x12mm Tubes 480122. Their designation as “EQUIP PARTS AND ACCESSORIES ONLY” suggests they are intended to be used within a larger system, and their primary “accessory” is the block or rack they are designed to fit into.

Customization options for this specific product are likely limited to the selection of the appropriate block or support system that matches the 20x12mm tube dimensions. These tubes themselves are precision components, and significant modification would likely compromise their intended function and accuracy. Their compatibility is determined by their standardized size, meaning they should integrate well with any lab equipment designed for this specific format.
