Product Overview

The Polylab Universal Combi Link Rack is a high-performance lab accessory engineered to enhance test tube management, storage, and workflow efficiency across diverse lab environments. Unlike standard tube holders, this rack offers customizable modularity, durable build quality, and chemical resilience—making it ideal for intensive use in clinical, educational, and industrial laboratories.

Crafted from autoclavable polypropylene, the rack is resistant to high heat, corrosion, and common lab chemicals. It can safely be sterilized, reused, and handled under sterile conditions, providing long-term reliability and reducing the risk of cross-contamination during sensitive experiments.

Modular and Expandable Design

The standout feature of the rack lies in its interlocking system—each unit can be linked horizontally or vertically, allowing labs to build custom storage arrays that suit changing requirements. Whether you’re processing small batches or managing hundreds of test tubes, the rack scales with your needs without occupying excessive benchtop space.

This flexibility makes it ideal for workflows involving multiple tube sizes—from microtubes to 18 mm culture tubes. The rack can be rearranged instantly, eliminating the need to maintain different racks for different tube formats.

Sample Stability and Visibility

Each well is precision-molded with rounded edges to ensure a snug yet gentle grip on the test tube, preventing accidental tipping or sliding. The open-frame layout supports rapid labeling and easy tube identification—crucial during time-sensitive tasks like heating, mixing, or reagent addition.

The reinforced base structure keeps the rack stable even when fully loaded, while the light weight allows for safe and convenient movement between stations or storage spaces.

Laboratory Space Optimization

For labs facing space constraints, this rack is a game-changer. Its compact footprint allows it to fit in tight areas like fume hoods, cold storage units, or sterile workstations. When interlocked, racks require no additional shelving—an ideal solution for maximizing efficiency on limited lab counters.

Color-Coded Sample Organization

With multiple color variants available, labs can establish visual cues for organizing samples by experiment, testing stage, or researcher. This system reduces confusion, improves tracking, and boosts safety—especially in shared laboratory settings.

Built for Practical Use

Whether you’re in pharma R&D, academic teaching labs, diagnostics, or material science, this rack simplifies test tube handling, minimizes breakage risk, and optimizes sample workflows. It’s engineered not just for holding tubes but for enhancing productivity, cleanliness, and organization.
