Breaking Down the Features of VWR Accessory Hematocrit Tube Reader C2300-77-VWR
Specifications
The VWR Accessory Hematocrit Tube Reader C2300-77-VWR is a specialized accessory, and its specifications are geared towards its singular function. Its primary role is to facilitate the reading of hematocrit values directly from spun capillary tubes. The product description highlights its ease of use and its compatibility with VWR centrifuges, implying a direct fit or intuitive placement onto the centrifuge rotor.
The key feature is its convenient measurement capability without requiring the removal of tubes from the rotor. This is a significant advantage as it minimizes sample handling and potential contamination or disruption of the packed cell column. The design relies on a simple placement mechanism where the reader sits atop the rotor, and a corresponding value is read from an integrated graph or scale.
This straightforward approach translates directly into a faster workflow and reduced risk of error compared to manual caliper measurements or visual estimation. The absence of complex electronic components means fewer potential points of failure, contributing to its perceived reliability and longevity in a busy lab environment. While specific dimensions or material composition beyond general “quality” aren’t detailed, its function points towards durable plastics and a clear, robust viewing mechanism.
Performance & Functionality
The core function of the VWR Accessory Hematocrit Tube Reader C2300-77-VWR is to provide accurate hematocrit percentage readings. In practice, it excels at this task. The design leverages a graphical scale that allows for a clear interpretation of the packed red blood cell volume relative to the total blood column.
Its main strength lies in its speed and direct-read capability. Once the centrifugation is complete, a quick placement of the reader and an observation of the scale provides an immediate result. This is a significant improvement over methods requiring manual measurement with a ruler or calipers, which can be time-consuming and introduce parallax errors.
The primary limitation, inherent in its design, is that it relies on the quality of the spin. If the centrifugation isn’t optimal, resulting in poorly separated layers or jagged meniscus, the accuracy of the reading will be compromised, regardless of the reader’s quality. However, when used with a well-performing centrifuge and properly prepared samples, it meets and often exceeds expectations for a dedicated accessory like this.
