Color/Style Display

Transparent Thickened Version: Specially designed for laboratories needing to observe contents, allowing direct viewing of waste types and liquid levels while maintaining super strong leak-proof performance, suitable for most conventional laboratories.
Yellow Biohazard Version: Printed with internationally recognized biohazard symbols, used to collect waste with potential biological risks, such as cultures, serum, tissue samples, etc., complying with biosafety laboratory regulations.
Red Chemical Hazard Version: Specially designed for chemical laboratories, used to collect chemical hazardous waste, printed with GHS chemical hazard symbols, with conspicuous red color reminding operators to pay attention to safety.

Material and Process Details

Made of medical-grade LDPE (Low-Density Polyethylene) and HDPE (High-Density Polyethylene) blended in a golden ratio, with LDPE providing excellent flexibility and sealing properties, and HDPE providing outstanding strength and chemical resistance. The product has a uniform thickness of 0.07mm, produced through special three-layer co-extrusion technology, forming a perfect micropore-free barrier layer.

The bag bottom adopts a "W"-shaped heat-sealing process, solving the problem of easy leakage when loading liquid in conventional straight-line sealed bags, enhancing corner pressure resistance, with a bottom seal tensile strength of 16N/15mm, 2 times that of ordinary waste bags. The material includes specially formulated UV stabilizers and antioxidants, making the product resistant to aging under strong laboratory lighting conditions, extending its service life.

To meet special laboratory requirements, anti-static agents have been added to the material, with surface resistivity controlled within the range of 10^9-10^12Ω, effectively preventing static attraction of dust and potential spark risks. The product undergoes strict quality control testing, including leakage testing, tensile testing, puncture testing, and chemical compatibility testing, with quality inspection reports provided for each batch, ensuring stable and reliable performance.

Application Scenarios

PCR Laboratory: Processes approximately 50-100 nucleic acid extraction and amplification samples daily, generating a large number of microtubes and tips containing primers and buffers. Leak-proof laboratory waste bags ensure that liquids potentially containing gene fragments do not spill, preventing cross-contamination.
Medical Laboratory Department: Analyzes 200+ patient specimens daily. The 60×80cm size waste bag can meet a full day's waste collection needs, with strong chemical resistance safely accommodating waste containing various laboratory reagents.
Pathology Laboratory: Processes irritating organic solvent waste liquids such as formalin and xylene generated during tissue fixation and staining. Ordinary garbage bags would be dissolved, while these professional leak-proof bags effectively withstand these solvents.
Microbiology Laboratory: Collects used culture dishes, inoculation loops, and waste potentially containing microorganisms. The leak-proof design ensures potential pathogens do not leak, protecting laboratory personnel and the environment.
Biochemistry Laboratory: Stores various waste liquids and consumables generated during protein purification, enzymology experiments, etc. Leak-proof bags ensure that buffer solutions containing SDS, Tris, EDTA, and other chemicals do not leak and cause environmental pollution.

Usage Steps

Preparation Work: Select the appropriate size based on the waste volume, check if the bag body is intact.
Correct Installation: Place the medical waste bag on a dedicated medical waste container, fold the bag opening outward covering the rim by at least 10cm, ensuring stability without slipping.
Standard Disposal: According to the Medical Waste Classification Catalog, put infectious waste into yellow marking bags, not mixing with other categories of waste, not exceeding 3/4 of the bag's capacity.
Three-Layer Sealing: When the waste reaches an appropriate amount, carefully lift the bag opening, fold the inner layer inward to form the initial seal; then use the provided dedicated tie at a position 5cm above the fold to tighten, forming the second layer of sealing; finally, fold the bag opening above the tie and fix with a second tie, forming three layers of protection.
Information Recording: Use a ballpoint pen to fill in department, date, waste type, handler, and other information in the record area of the bag, ensuring clear and legible writing.
Safe Storage: Place the well-sealed medical waste bags in the designated medical waste temporary storage area, avoiding direct sunlight and rain, waiting for regular collection by professional institutions.
Handover Registration: When handing over waste, jointly verify the bag information with collection personnel and sign to confirm, completing the handover record, ensuring full traceability.

Usage Steps

Preparation Stage: Based on the type and quantity of laboratory waste, prepare an appropriate number of leak-proof waste bags, confirm the bag body is undamaged.
Correct Installation: Place the waste bag on a dedicated waste container, fold the bag opening outward covering the container edge by at least 10cm, ensuring stability without slipping.
Classified Disposal: According to laboratory waste management procedures, put the corresponding category of waste into the bag, sharp objects should first be placed in dedicated sharps containers. Liquid waste should be sealed before disposal to prevent splashing.
Control Capacity: The amount of waste should not exceed 3/4 of the bag's capacity, reserving enough space for safe sealing, with liquid waste not exceeding 1/3 of the total capacity.
Safe Sealing: Carefully tighten the bag opening, trying to expel excess air but avoiding squeezing the contents, use the provided dedicated ties to tightly seal 5cm above the bag opening.
Double Insurance: Perform a second tie closure 10cm above the first seal, forming a double seal, improving the safety factor.
Information Marking: Fill in laboratory name, date, waste type, responsible person, and other information in the bag's marking area, ensuring waste traceability.
Standard Storage: Place the sealed waste bags in the designated laboratory waste temporary storage area, avoiding direct sunlight and high-temperature environments, waiting for regular collection and processing by professional personnel.
