Stainless Steel Crucible Tongs United Scientific PTFE Tips UNSSTON09NS

Description

Product Overview

The United Scientific stainless steel crucible tongs are engineered to meet the rigorous demands of modern laboratories, educational environments, and home science enthusiasts. Constructed from premium 304 stainless steel, the tongs offer exceptional corrosion resistance, structural integrity, and a long service life even under repeated high‑temperature exposure. Each tong measures approximately 9 inches in total length, providing ample leverage while maintaining a compact profile that is easy to store and transport.

One of the standout features of this product is the PTFE‑coated tip segment, which extends roughly three inches from the gripping end. The PTFE coating creates a non‑stick surface that minimizes material adhesion, allowing users to handle delicate crucibles, melt‑resistant glassware, and other hot vessels without the risk of residue buildup or surface damage. The coating also reduces the likelihood of accidental slippage, enhancing safety during critical procedures such as melting, annealing, and sample transfer.

The tongs are fully autoclavable, meaning they can be placed in a standard autoclave cycle for sterilization without compromising the integrity of the stainless steel or the PTFE coating. This feature is particularly valuable in microbiology, chemistry, and materials science labs where cross‑contamination must be strictly controlled. The design incorporates a smooth, ergonomic handle that fits comfortably in the hand, reducing fatigue during extended use and providing precise control over the movement of hot objects.

Usage

These crucible tongs are versatile enough to be employed across a wide range of applications. In academic laboratories, they are ideal for undergraduate chemistry courses where students regularly melt metals, synthesize compounds, or perform thermal analyses. The PTFE‑coated tips ensure that crucibles can be lifted cleanly from furnaces or hot plates, while the autoclavable construction allows the tongs to be quickly sanitized between experiments.

In industrial research settings, the tongs serve as reliable tools for handling high‑purity crucibles used in semiconductor manufacturing, alloy development, and advanced material synthesis. The stainless steel body resists chemical attack from aggressive reagents, and the PTFE coating protects both the tool and the crucible from abrasive wear.

For hobbyists and home experimenters, the tongs provide a professional‑grade solution for small‑scale metal casting, glassblowing, and educational demonstrations. Their compact size makes them easy to store in a home workshop, and the ability to autoclave them ensures that even occasional users can maintain a high level of cleanliness.

Why Choose Us

United Scientific has a long history of delivering high‑quality laboratory equipment that meets stringent industry standards. Our crucible tongs are manufactured in a controlled environment using certified 304 stainless steel, guaranteeing uniform composition and consistent performance across every unit. The PTFE coating is applied using a proprietary process that bonds the polymer to the steel surface at a molecular level, delivering a durable, non‑reactive finish that withstands repeated heating cycles.

Quality assurance is a cornerstone of our production philosophy. Each batch of tongs undergoes rigorous testing for tensile strength, temperature tolerance, and coating adhesion before it leaves the factory. This systematic approach ensures that every pair of tongs you receive performs exactly as advertised, providing confidence in critical experimental workflows.

In addition to product durability, United Scientific offers responsive customer support and a straightforward warranty policy. Should you encounter any issues related to material defects or coating performance, our technical team is ready to assist with troubleshooting, replacement, or repair options, reinforcing our commitment to long‑term customer satisfaction.

FAQ

Can the PTFE coating withstand direct flame exposure?

The PTFE coating is designed to resist temperatures up to approximately 260 °C (500 °F). For applications involving direct flame or higher temperatures, it is recommended to limit exposure time and allow the coating to cool gradually to preserve its integrity.

Is the tong suitable for handling glass crucibles?

Yes, the smooth stainless steel body combined with the PTFE‑coated tips provides a gentle yet secure grip on glass crucibles, reducing the risk of chipping or breakage during transfer.

How many autoclave cycles can the tongs endure?

Our testing indicates that the tongs maintain their structural and coating performance for at least 50 standard autoclave cycles, far exceeding typical laboratory usage patterns.

What is the maximum weight the tongs can safely lift?

The tongs are rated to support up to 2 kg (4.4 lb) of crucible weight, which covers the majority of standard laboratory crucibles and small melt containers.

Do you offer replacement parts for the PTFE tips?

While the PTFE coating is intended to be long‑lasting, we do provide replacement tip kits for situations where the coating may become worn or damaged, ensuring continued optimal performance.
