Laboratory Sample Bags, With Document Pouch, Medical-Grade Leak-Proof Design

Core Selling Points

Innovative Document Pouch Design: External independent document pouch measuring 12 inches × 14 inches, perfectly accommodating A4 laboratory records, medical history summaries, and test application forms, paper documents stored separately from samples, reducing sample record error rate by 87%.
Excellent Leak-Proof Performance: Using medical-grade LDPE material, thickness reaching 4 MIL, passed ISO 16101 liquid sealing test, leak testing pass rate reaching 99.9%, effectively preventing cross-contamination and environmental hazards caused by sample liquid leakage.
Exceptional Transparency: Material transparency reaching over 95%, sample color, precipitation, turbidity, and other characteristics clearly visible, reducing opening inspection frequency by 76%, lowering sample contamination risk.
High-Strength Durability: Tear resistance strength reaching 8.5N, puncture resistance performance 65% higher than ordinary sample bags, not easily damaged even when loaded with sharp sampling tools, reducing sample loss risk by 92%.
Compliant with International Standards: Design complies with CAP (College of American Pathologists) and CLIA laboratory certification standards, passed ISO 9001, 13485 quality management system certification, meeting GLP (Good Laboratory Practice) requirements.

Material and Process Details

This product's main body uses medical-grade low-density polyethylene (LDPE) material, thickness precisely controlled at 4 MIL (0.1016mm), manufactured through special blow molding process, ensuring material uniformity deviation controlled within ±0.005mm. The external document pouch uses integrated heat sealing technology with the main bag, seam strength reaching 6.8N/cm, no cracking after 100,000 bending tests. The material is added with anti-UV stabilizers, maintaining stable physical properties for over 24 months under natural light conditions. Special surface treatment controls the inner surface friction coefficient between 0.25-0.35, effectively reducing static adsorption, facilitating small volume sample placement and removal. All materials comply with FDA 21 CFR 177.1520 food-grade material standards, with no harmful substance release.

Pathology Laboratory: Collecting an average of 180 tissue sections and cytology samples daily, document pouch storing pathology application forms and clinical information, ensuring sample traceability, reducing repeat sampling rate by 78%, improving diagnostic accuracy.
Multi-Center Clinical Research: Cross-institutional research sample transport over 800+ times monthly, standardized sample bag design ensuring consistency of sample handling processes between different centers, sample intact arrival rate improved to 99.5%, data comparability significantly improved.

Usage Steps

Bag Preparation: Take a sample bag from the packaging, confirm both main bag and document pouch are intact, gently shake open to fully expand the bag, avoiding inner wall adhesion.
Document Placement: Insert sample-related documents (such as test application forms, medical history summaries, experiment records) into the external document pouch, ensuring documents are fully inserted and do not exceed the pouch opening.
Sample Loading: Place well-sealed sample containers (such as blood collection tubes, urine cups, culture dishes) into the main bag, ensure the outer surface of containers is dry and uncontaminated, avoid overfilling.
Record Checking: Confirm the information in the document pouch matches the samples in the main bag, verify sample numbers, patient information, and test items, preventing information mismatch.
Sealing Preservation: According to the sample bag design type, use self-sealing strips or adhesive tape to seal the bag opening, ensure completely sealed without gaps, mark preservation conditions (such as refrigeration, freezing).

Maintenance Guide

Storage Environment: Store in temperature 15-25°C, relative humidity 30%-60% environment, avoid direct sunlight and humid environments, away from heat sources and strong oxidants.
Usage Period: Unopened products have a shelf life of 36 months under appropriate conditions, after opening it is recommended to use within 12 months, regularly check the appearance and resilience of inventory products.
Batch Management: Laboratories should establish sample bag usage records, recording batch numbers and usage dates, implementing first-in-first-out principle, regularly sampling inventory products for performance testing.
Quality Testing: At least 2% of inventory sample bags should be sampled quarterly for leak-proof testing (injecting 50ml water, sealing for 24 hours) and document pouch adhesion strength testing.
Low-Temperature Usage Precautions: Before use in low-temperature environments (below -20°C), should be placed at room temperature for 30 minutes to restore material flexibility, avoiding low-temperature embrittlement leading to damage.
