PROOF PLANE

Proof Plane

Product Description
A Proof Plane is a flat, thin, and smooth metallic or plastic tool used in laboratory and educational settings primarily for transferring small amounts of powdered substances or samples. Its precise, rigid surface enables the easy lifting and placement of powders onto other surfaces such as balances, microscope slides, or reaction vessels without contamination. Often used in qualitative analysis, the Proof Plane facilitates accurate handling of chemicals, minimizing spillage and waste. Available in various sizes and materials, it is an essential apparatus for fine sample manipulation in analytical and teaching laboratories.

Uses
Primary Uses
Laboratory and Educational Applications

• Transferring powdered chemicals accurately to balances for weighing. 
• Collecting and moving small solid samples during qualitative tests. 
• Applying powders evenly on microscope slides or other surfaces. 
• Assisting in sample preparation in analytical chemistry. 
• Avoiding contamination by providing a clean, dedicated tool for powders. 

Secondary Uses
Research and Industrial Uses

• Used in pharmaceutical labs for handling fine powders during formulation. 
• Employed in quality control labs for sample handling. 

Key Attributes
Basic Identification Attributes

• Material: Usually stainless steel, aluminum, or durable plastic. 
• Shape: Flat, thin, rectangular or slightly curved blade attached to a handle. 
• Size: Small and lightweight for precise control. 
• Finish: Smooth, polished surface to prevent powder adherence. 

Physical & Chemical Properties

• Chemical Resistance: Resistant to most laboratory chemicals (metal or plastic grade dependent). 
• Durability: Sturdy yet lightweight for ease of use. 
• Surface: Smooth and non-porous to prevent sample contamination. 

Safety & Hazard Attributes

• Sharp edges may cause minor cuts; handle carefully. 
• Must be cleaned regularly to avoid cross-contamination. 

Storage & Handling Attributes

• Store in a clean, dry place to prevent corrosion (if metal). 
• Clean thoroughly after each use with suitable solvents or detergents. 
• Inspect for damage or corrosion before use. 

Regulatory & Compliance Attributes

• Manufactured to laboratory equipment standards. 
• Suitable for use in GMP and GLP compliant laboratories. 

Environmental & Health Impact

• Materials are generally recyclable (metal/plastic). 
• Durable design reduces frequent replacement and waste.
