Breaking Down the Features of Nalge Nunc Unwire Racks, ResMer Resin, NALGENE 5970-0030
Specifications
The Nalge Nunc Unwire Racks, ResMer Resin, NALGENE 5970-0030 boasts a set of specifications designed for serious laboratory application. It is specifically engineered to accommodate tubes with an Outer Diameter (O.D.) of 30mm. This particular rack configuration holds a generous 24 tubes, which is ideal for workflows requiring a significant number of samples.
The material is a key feature: ResMer Resin. This advanced polymer is renowned for its excellent chemical resistance, meaning it won’t degrade when exposed to common laboratory solvents and reagents. Crucially, this resin also allows the rack to be used over a wide temperature range, making it suitable for everything from refrigerated storage to immersion in water baths or even autoclaving.
The dimensions of the Nalge Nunc Unwire Racks, ResMer Resin, NALGENE 5970-0030 are specified as 28.3 x 11 x 8.3 cm (11 x 4 ¼ x 3 3/16 inches). These dimensions are optimized to fit within standard laboratory bench space and incubators, while the height ensures stability. The unit of purchase is Each, meaning you receive one rack per order.
These specifications matter because they translate directly into reliable performance in demanding laboratory environments. The precise tube diameter accommodation ensures that your valuable samples are held securely, preventing accidental spills or contamination. The ResMer Resin’s temperature and chemical resistance mean this rack will not become a point of failure in your experimental setup, unlike inferior materials that can crack, warp, or leach unknown substances. The thoughtful dimensions ensure it integrates seamlessly into existing lab infrastructure, maximizing your workspace efficiency.
Performance & Functionality
In practice, the Nalge Nunc Unwire Racks, ResMer Resin, NALGENE 5970-0030 excels at its primary function: securely holding 30mm tubes. Its performance is consistently high, providing a stable platform for sample preparation, incubation, and transport. The three-tier design offers good accessibility to each tube without compromising the overall structural integrity of the rack.
A significant strength is its autoclavable nature. Repeated sterilization cycles have shown no adverse effects on the rack’s material or form. This is absolutely critical for maintaining sterile laboratory conditions, and the Nalge Nunc product delivers this with unwavering reliability. The functional design also includes letters and numbers on the top tier, which is a minor but incredibly helpful feature for tube identification, especially when dealing with numerous samples.
The only minor point that could be seen as an area for improvement, though not a true weakness, is its bright white color. While excellent for visibility, in a lab environment with many white surfaces, it can sometimes blend in if not paid close attention to. However, this is easily overcome by its inherent robustness and functional superiority. It consistently meets and often exceeds the expectations set by its specifications.
Design & Ergonomics
The design of the Nalge Nunc Unwire Racks, ResMer Resin, NALGENE 5970-0030 prioritizes both form and function. The build quality is immediately apparent; it feels solid and substantial, reflecting the use of high-grade ResMer Resin. The weight is appropriate for its size and intended use – heavy enough to feel stable but not so heavy as to be cumbersome.
It is exceptionally user-friendly. There is virtually no learning curve; it’s a simple matter of placing tubes into the designated slots. The raised edge around the top tier not only aids in tube identification but also provides a subtle lip that helps prevent tubes from being accidentally knocked out. The large end plates are designed to accept labels easily, a small but significant ergonomic consideration for busy researchers.
Durability & Maintenance
The durability of the Nalge Nunc Unwire Racks, ResMer Resin, NALGENE 5970-0030 is exceptional.
