Let’s Dive into Nalge Nunc Unwire Racks, ResMer Resin, NALGENE 5970-0020
The Nalge Nunc Unwire Racks, ResMer Resin, NALGENE 5970-0020 isn’t exactly the kind of gear that screams “adventure,” but in the world of tactical and outdoor science, reliable sample management is absolutely crucial. These racks, manufactured by NALGENE Nunc, offer a seemingly simple solution: a durable, chemically resistant, and autoclavable way to organize and transport test tubes. My initial thought was, “How much can you really say about a test tube rack?” Let’s find out.
My need for these racks stems from a unique intersection of passions: field research and a need for a reliable way to store collected samples. I’ve always tinkered with improvised field labs. I needed a durable rack that could handle harsh conditions, temperature fluctuations, and the occasional chemical spill – something beyond the flimsy cardboard boxes I was previously using.
Unboxing the Nalge Nunc Unwire Racks, ResMer Resin, NALGENE 5970-0020, my first impression was of a solid, well-constructed piece of kit. The white ResMer resin feels substantial and the three-tier design looks intelligently laid out. It’s lightweight, but not flimsy.
I considered the Bel-Art SP Scienceware Test Tube Rack and the Heathrow Scientific HD29001B Benchtop Rack, both common alternatives. However, the NALGENE Nunc stood out because of the temperature range supported by ResMer resin and its claim of excellent chemical resistance; important for the variety of chemicals I might encounter in the field. This rack was also autoclavable, further enhancing its utility for sterile sample management.
Initially, I was cautiously optimistic. Could this seemingly mundane piece of lab equipment truly enhance my fieldwork? Only real-world testing would tell.
