Real-World Testing: Putting GE, Blue Dextran 2000, 10g, 17-0360-01 to the Test

First Use Experience

My initial testing of the Blue Dextran 2000 took place on our standard laboratory bench, specifically within the context of calibrating a gel filtration column for protein purification. The material was dispensed directly from the 10g container, dissolved in a buffer solution, and then applied to the column. Its vibrant blue color immediately provided visual confirmation of its application and flow through the column, a characteristic that is incredibly useful for tracking flow paths and assessing void volumes. No discernible learning curve was associated with its use; it behaves exactly as a standard dextran polysaccharide would, dissolving readily and interacting predictably within the chromatographic matrix. The most significant positive surprise was the intensity and clarity of the blue hue, which remained consistent across multiple preparations, making visualization exceptionally straightforward.

Extended Use & Reliability

Over several months of regular laboratory use, this Blue Dextran from GE has proven to be a dependable reagent. It has been used for column packing verification, testing buffer flow rates, and as a high-molecular-weight marker in gel electrophoresis. Even after being stored in a cool, dry place and subjected to repeated opening and closing of its container, the material has maintained its integrity and solubility. There have been no signs of degradation or performance degradation, such as clumping or reduced staining intensity. Compared to some less reputable brands where I’ve experienced batch-to-batch variability, this GE product has offered a remarkable consistency, which is paramount for reproducible scientific results. Its ease of use extends to its maintenance; simply re-sealing the container properly after each use is sufficient.

Breaking Down the Features of GE, Blue Dextran 2000, 10g, 17-0360-01

Specifications

The GE, Blue Dextran 2000, 10g, 17-0360-01 comes in a 10g quantity, which is a substantial amount for most routine laboratory applications, offering excellent value and longevity. The product is specifically identified as Blue Dextran 2000, implying a specific molecular weight range, typically around 2,000,000 Daltons. This high molecular weight is critical for its function as a marker, allowing it to elute at or near the void volume in gel filtration chromatography, effectively marking the maximum exclusion limit of the column. The packaging is a standard laboratory-grade container, designed for easy dispensing while maintaining product integrity. Its role as a replacement or supplement for the Gel Filtration HMW Calibration Kit 28-4038-42 directly highlights its intended application in precisely this area. This substantial quantity and its established molecular weight make it ideal for method development and routine quality control.

Performance & Functionality

In its primary function as a high-molecular-weight marker, this Blue Dextran performs exceptionally well. Its high molecular weight ensures it elutes predictably at the void volume, providing a clear and unambiguous reference point for assessing column performance and calibration. The vivid blue coloration is a significant functional advantage, allowing for straightforward visual tracking of the mobile phase front during chromatography runs. It also serves as an excellent marker for flow path integrity in agarose or polyacrylamide gels, where its intense color makes it easily visible without the need for specific staining reagents. This product reliably meets, and often exceeds, the expectations for a calibration standard in its class, especially when considering its performance against price.

Design & Ergonomics

The design of the GE, Blue Dextran 2000, 10g, 17-0360-01 is purely functional, focusing on the delivery of a pure, well-characterized chemical reagent. The material itself is a fine powder, which is the standard form for dextrans of this nature, facilitating easy weighing and dissolution. The 10g container is a common laboratory size, offering a good balance between bulk for cost-effectiveness and manageability for benchtop use. There are no complex ergonomic considerations beyond the standard practice of careful handling of laboratory chemicals; it is designed to be scooped or measured out easily. The overall feel is one of a professionally prepared chemical reagent, ready for immediate laboratory integration.

Durability & Maintenance

As a chemical reagent stored under appropriate conditions, the durability of the GE, Blue Dextran 2000, 10g, 17-0360-01 is effectively indefinite if kept dry and at a suitable temperature. The primary maintenance concern is ensuring the container is securely sealed after each use to prevent moisture absorption, which could lead to clumping and reduced solubility over time. Its powder form means there are no moving parts or delicate components to wear out. Based on my experience with similar reagents, this product is built to last for years in a laboratory setting, provided it is handled and stored correctly. Potential failure points are minimal, primarily relating to user error in storage rather than inherent product flaws.

Accessories and Customization Options

The GE, Blue Dextran 2000, 10g, 17-0360-01 is primarily sold as a standalone reagent, and as such, it does not come with any specific accessories. Its customization lies not in modifying the product itself, but in how it is applied. For instance, its dissolution in different buffer systems allows for tailored experimental conditions. The absence of included needles or specific dispensing tools is typical for bulk chemical reagents, as laboratories usually have their own preferred spatulas, scoops, and weighing dishes. Compatibility is straightforward; it dissolves in aqueous solutions, making it compatible with most common laboratory buffers used in chromatography and electrophoresis.

Pros and Cons of GE, Blue Dextran 2000, 10g, 17-0360-01

Who Should Buy GE, Blue Dextran 2000, 10g, 17-0360-01?

This product is ideally suited for laboratory technicians, researchers, and scientists involved in protein purification, molecular biology, and biochemical analysis.
