Porcelain Crucible 200ml with Lid QWORK Durable Labware Pack of 4

Description

Product Overview

The QWORK 200ml porcelain crucible with lid is engineered for demanding laboratory environments where precision, durability, and thermal performance are non‑negotiable. Crafted from high‑grade ceramic, the crucible can endure temperatures up to 1200 °C without cracking, warping, or losing its structural integrity. This exceptional heat resistance makes it suitable for a wide range of applications, from simple heating of solid samples to complex processes such as evaporation, concentration, and crystallization of solutions.

Each crucible features a smooth, glazed interior that minimizes the adhesion of molten or reactive materials, ensuring that the purity of your samples remains uncompromised. The smooth surface also simplifies post‑process cleaning, reducing the time and effort required to maintain a contaminant‑free workspace. The lid, made from the same high‑temperature porcelain, provides a secure seal that helps retain heat, prevent oxidation, and protect the contents from airborne contaminants.

Dimensionally, the crucible offers an 80 mm (3.15″) opening, a 43 mm (1‑11/16″) base, and a total height of 70 mm (2‑3/4″). This geometry balances a generous 200 ml capacity with a compact footprint, allowing it to fit comfortably into standard laboratory furnaces, hot plates, and drying ovens. The four‑pack configuration ensures that you have a consistent supply of identical crucibles, which is essential for repeatable experiments and batch processing.

Usage

Designed with versatility in mind, the QWORK porcelain crucible excels in educational settings, research laboratories, and small‑scale industrial processes. In high school chemistry classes, students can safely conduct flame tests, metal oxidation studies, and basic synthesis reactions, benefiting from the crucible’s robust construction and clear visual cues. University laboratories often employ these crucibles for advanced analytical techniques, such as thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), where precise temperature control and material stability are critical.

Beyond academic environments, the crucible is well‑suited for quality‑control labs in pharmaceutical, petrochemical, and materials science industries. Its ability to withstand aggressive chemicals and high temperatures enables users to perform tasks like catalyst activation, alloy melting, and glass fiber production with confidence. The secure lid also makes the crucible an excellent choice for processes that require an inert atmosphere or need to minimize exposure to moisture and oxygen.

FAQ

What temperature range can the crucible safely handle?

The QWORK porcelain crucible is rated for continuous use up to 1200 °C. It maintains structural integrity and dimensional stability throughout heating cycles, making it suitable for most high‑temperature laboratory procedures.

Is the crucible compatible with acidic or basic solutions?

Yes. The glazed ceramic surface offers excellent chemical resistance to both strong acids and bases. However, for highly corrosive mixtures, it is recommended to rinse the crucible promptly after use to prolong its lifespan.

Can the lid be used independently for other laboratory tasks?

The lid is designed specifically for the accompanying crucible, matching its diameter and thermal properties. While it can serve as a temporary cover for small containers, using it outside its intended pairing may compromise the seal and heat retention performance.

How should I clean the crucible after a reaction?

Allow the crucible to cool to room temperature, then rinse with warm water and a mild detergent. For stubborn residues, a gentle scrub with a non‑abrasive brush is sufficient. Avoid using harsh chemicals or metal scouring pads, as they can damage the glaze.

What is the warranty or return policy for this product?

QWORK provides a 90‑day warranty against manufacturing defects. If you receive a damaged or defective item, contact our customer support team with your order details, and we will arrange a replacement or refund according to our return policy.
