L Shaped Spreader

The GISCOM L Shaped Spreader is a sterile, precision-molded instrument designed for uniform spreading of liquid samples such as inoculum, cultures, or suspensions across the surface of agar plates. Its smooth, angled “L” design ensures streak-free application without cutting or disturbing the medium. This makes it an essential tool for consistent colony distribution in microbiology, QC/QA testing, and research environments.

Key Features

• Smooth, burr-free surface ensures even and gentle spreading of samples
• Sterile and ready to use, eliminating flame sterilisation steps
• Angled “L” design allows easy manoeuvrability inside Petri dishes
• Lightweight, ergonomic structure for precise handling
• Non-toxic and chemically inert for reliable microbial work
• Rigid yet flexible to prevent cracking during use
• Disposable design reduces contamination risk and improves workflow efficiency

Material Specifications

• Material: High-quality Polypropylene (PP)
• Thermal Properties: Heat-stable up to moderate temperatures; suitable for limited autoclaving depending on batch (avoid excessive heat)
• Chemical Resistance: Excellent resistance to aqueous solutions and standard laboratory reagents
• Mechanical Properties: Strong, durable, and shape-retaining under routine lab use
• Compliance: Manufactured under ISO 9001:2015 certified quality standards

Technical Specifications

• Design: Standard “L”-shaped laboratory spreader
• Dimensions: Available in standard microbiology lengths for Petri dish compatibility
• Accuracy/Tolerance: Engineered for uniform, controlled sample spreading
• Calibration: Not applicable (non-volumetric instrument)
• Sterilisation: Typically E.O. sterilised (batch-specific)
• Accessories: No additional accessories required

Handling & Precautions

• Use immediately after opening the sterile pack to maintain asepsis
• Avoid applying excessive downward force to prevent gouging agar
• Do not overheat; limited resistance to high-temperature autoclaving
• Dispose of in compliance with biohazard waste guidelines
• Store in a cool, dry, dust-free environment
• Do not reuse if sterility is compromised

Applications

• Microbiological plating and CFU (colony-forming unit) determination
• Even distribution of bacterial, fungal, and microbial suspensions
• Ideal for pharmaceutical microbiology, biotech R&D, food & water testing labs, environmental monitoring, and academic research
• Essential for QC/QA laboratories performing microbial load or purity assessments
• Useful in daily workflows requiring rapid, consistent, and sterile inoculum spreading
