Micro Pestle

The GISCOM  Micro Pestle is a precision-moulded, double-ended pestle designed for efficient grinding, homogenization, and mixing of biological samples in microcentrifuge tubes. One end fits 1.5 mL tubes, while the opposite end is optimized for 0.5 mL tubes, enabling versatile sample processing. It is essential for molecular biology, cell lysis, DNA/RNA extraction, protein studies, and sample preparation workflows requiring uniform disruption with minimal contamination risk.

Key Features

• Dual-ended design fits both 1.5 mL and 0.5 mL microcentrifuge tubes
• Smooth, uniform surface ensures controlled homogenization without damaging tubes
• Disposable and hygienic, minimizing cross-contamination
• Lightweight and ergonomic for fatigue-free manual grinding
• Chemically inert and non-toxic for sensitive biological samples
• Rigid construction prevents bending or breakage during vigorous use
• Ideal for small-volume sample prep in molecular and cell biology applications

Material Specifications

• Material: High-grade Polypropylene (PP) laboratory plasticware
• Thermal Properties: Withstands routine lab temperatures; limited autoclave tolerance depending on batch
• Chemical Resistance: Excellent resistance to alcohols, buffers, mild acids, and common lab reagents
• Mechanical Properties: Strong, impact-resistant, and designed for repetitive grinding
• Standards: Manufactured under ISO 9001:2015 compliant quality systems

 Technical Specifications

• Design: Double-ended pestle (1.5 mL end + 0.5 mL end)
• Dimensions: Standard lengths suitable for all microcentrifuge tube brands
• Accuracy/Tolerance: Production precision ensures a secure fit inside tubes
• Calibration: Not applicable (manual non-volumetric device)
• Sterilization: Available sterile or non-sterile (product variant dependent)
• Accessories Included: None required

Handling & Precautions

• Use gentle, vertical grinding motions to avoid tube cracking
• Ensure the pestle fits the correct tube size before use
• For sterile work, open the pack only at the time of application
• Avoid exposure to high autoclave temperatures unless specified for the batch
• Do not use with highly corrosive chemicals that may degrade polypropylene
• Dispose of in accordance with biohazard waste protocols when used with biological samples

Applications

• Homogenization of tissues, cells, and small biological samples
• DNA/RNA extraction workflows
• Protein sample preparation
• Grinding soft tissue for molecular biology and analytical procedures
• Ideal for pharmaceutical QC/QA labs, biotechnology facilities, academic research institutes, diagnostic labs, and industrial R&D
• Supports daily workflows in microbiology, genomics, and biochemical analysis
