The block’s design proved immediately effective. Each of the eight 16mm wells provided a stable cradle for my standard borosilicate glass and polypropylene test tubes. I tested it under conditions of frequent tube removal and replacement, a common scenario when processing multiple samples for PCR or gel electrophoresis. The block remained steadfast, its wells maintaining their integrity without any signs of deformation, even when tubes were inserted with slight force.
It was remarkably intuitive; there was no learning curve involved. The simple act of placing tubes into the wells was the only required interaction. The one minor surprise was how much cleaner my workspace immediately became. This simple solution eliminated the need for makeshift tube holders or the precarious leaning of tubes against other equipment.
Extended Use & Reliability
Weeks turned into months, and this sectional block has become a permanent fixture on my lab bench. It consistently holds its eight 16mm tubes through countless experimental cycles. I’ve subjected it to light splashes from buffer solutions, and while not designed for submersion, it has shown no signs of degradation or chemical staining.
Durability has been excellent. Despite the weight of filled tubes and the occasional accidental bump, there are no cracks, no warping, and the wells remain consistently sized. The matte black finish has held up well, showing only minor scuffs that are typical of any well-used lab item. Its performance has remained unchanged since day one, a testament to its robust build.
Maintenance is practically non-existent. A quick wipe with a damp cloth or a standard lab disinfectant is all it takes to keep it clean and presentable. I haven’t needed to perform any specific care beyond regular benchtop cleaning. Compared to older, cheaper plastic racks I’ve used in the past, which often developed sharp edges or became brittle over time, this VWR sectional block feels like it’s built to last.
Specifications
The VWR Vwr Sectional Blk 16mm Tubes 984VWP16MMT is engineered with a clear purpose: to provide organized storage for eight 16mm diameter test tubes.

The block is specifically designed to fit onto VWR’s 135mm top plates, ensuring seamless integration into existing laboratory setups that utilize this VWR standard.
The material appears to be a high-density, chemical-resistant polymer, common in laboratory consumables for its durability and inertness. This ensures that the block won’t react with common lab chemicals or solvents, nor will it leach any compounds into your samples. The overall dimensions are optimized for bench space efficiency, providing a stable footprint for its eight-tube capacity, a significant improvement over a loose collection of tubes.
Its catalog number, 984VWP16MMT, is a key identifier for procurement and inventory management within research institutions. The internal catalog number listed, 89171-888, further aids in precise ordering. While the “Type: PL EQUIP/INST-$0-$499” classification indicates its place within the broader lab equipment category, its actual function is very specific. This sectional block represents a focused solution, avoiding the bulk of larger multi-format racks, which might be overkill for labs consistently using 16mm tubes.
Performance & Functionality
The primary function of this sectional block is to hold 16mm test tubes securely and upright, and it performs this task admirably. The eight individual wells are precisely dimensioned to accommodate standard 16mm tubes, preventing them from tipping over even when handled with moderate force. This stability is paramount in preventing spills of valuable or hazardous reagents.
Its greatest strength lies in its simplicity and the precise fit it offers within the VWR system. For workflows that involve preparing multiple samples in 16mm tubes simultaneously, like serial dilutions or setting up cell cultures, the organization it provides is invaluable. It significantly reduces the time spent searching for misplaced tubes or tidying up a cluttered bench.
A potential weakness, though not a flaw in its design, is its singular focus on 16mm tubes. If your lab utilizes a mix of tube sizes, this block alone won’t be sufficient, and you’d need to consider a more versatile rack. However, for dedicated 16mm tube users, its focused functionality is precisely why it excels. It meets expectations fully for its intended use, offering reliability and efficiency where it counts.
Design & Ergonomics
The design of the VWR Vwr Sectional Blk 16mm Tubes 984VWP16MMT is a masterclass in functional minimalism. Its matte black, uniform finish contributes to a clean aesthetic on the lab bench, and it effectively hides minor dirt or scuffs.
