Zonon 64pcs 03µm Filter Paper Discs & Stoppers for Mushroom Growing

Description

Product Overview

The Zonon 64‑piece filter kit is engineered for precision and durability in demanding laboratory and cultivation environments. Each synthetic filter paper disc is crafted from high‑quality polymer fibers that provide a uniform 0.3 µm pore size, ensuring reliable filtration of microscopic contaminants while maintaining optimal airflow. The accompanying 100 rubber stoppers are molded from a resilient elastomer that resists deformation, chemical corrosion, and repeated autoclave cycles, making them suitable for both liquid and solid media containment.

Designed with a 13.2 mm diameter, the filter discs fit seamlessly into standard wide‑mouth canning jar lids, providing a secure barrier that prevents cross‑contamination during mushroom spawn propagation. The rubber stoppers feature a smooth, tapered profile that creates an airtight seal without the need for additional gaskets, simplifying setup and reducing the risk of leaks. Together, these components form a comprehensive solution that supports the entire lifecycle of mushroom cultivation, from inoculation to fruiting.

Beyond mushroom cultivation, the kit serves a broad range of laboratory applications, including microbiology, cell culture, and chemical analysis. The high heat resistance of the filter paper allows for autoclave sterilization at temperatures up to 121 °C, while the stoppers withstand pressures up to 2 atm without compromising integrity. This combination of performance attributes makes the Zonon kit a versatile, cost‑effective choice for research institutions, commercial labs, and hobbyist growers alike.

Usage

In mushroom cultivation, the filter discs are placed over the vent holes of wide‑mouth jars, creating a breathable yet contaminant‑free environment that promotes healthy mycelial growth. Users first sterilize the substrate and the jars, then allow them to cool before inserting the filter discs and sealing the lids with the rubber stoppers. This setup enables efficient gas exchange while protecting the culture from airborne spores and bacterial intrusion.

For laboratory protocols, the filter discs can be attached to the openings of reaction vessels, filtration units, or sampling ports where fine particulate removal is essential. The rubber stoppers provide a reliable seal for reagents, buffers, or culture media, facilitating repeated access without compromising sterility. Their reusable nature reduces waste and operational costs, especially in high‑throughput environments where frequent opening and closing of containers is routine.

When autoclaving, the filter paper’s heat‑stable composition ensures that pore structure remains intact, preserving filtration efficiency across multiple cycles. The rubber stoppers, formulated to resist degradation under high temperature and pressure, maintain their elasticity and sealing capability, eliminating the need for replacement after each sterilization run. This durability translates into consistent experimental conditions and reproducible results, critical factors for scientific rigor.

Why Choose Us

Zonon’s commitment to quality is reflected in every component of this filter kit. The synthetic filter paper undergoes rigorous testing for uniform pore distribution, ensuring that each disc delivers the same filtration performance. This consistency is vital for experiments that require precise control over particle size exclusion, such as spore filtration or media clarification.

Our rubber stoppers are manufactured using a proprietary blend of elastomers that balances flexibility with chemical resistance. They are tested for compatibility with a wide range of solvents, acids, and bases, guaranteeing that they will not leach contaminants into sensitive samples. The stoppers also feature a smooth surface finish that minimizes microbial adhesion, further enhancing sterility during prolonged incubations.

FAQ

Can the filter discs be reused after autoclaving?

Yes, the synthetic filter paper is designed to withstand repeated autoclave cycles without losing its pore structure or filtration efficiency. After each sterilization, simply allow the discs to cool, inspect for any physical damage, and they are ready for reuse.

What types of liquids are compatible with the rubber stoppers?

The rubber stoppers are chemically resistant to a broad spectrum of solvents, acids, and bases commonly used in laboratory settings. They are suitable for sealing aqueous solutions, organic solvents, and even viscous media, making them versatile for many experimental protocols.

How do I attach the filter paper to a jar lid?

First, clean and thoroughly dry the lid surface to ensure optimal adhesion. Then, peel the protective backing from the synthetic filter paper and press it firmly onto the vent hole, ensuring a flat, wrinkle‑free seal. The stoppers can then be placed on the lid to complete the assembly.

Is the kit suitable for large‑scale commercial mushroom production?

Absolutely. The combination of high‑performance filter discs and robust rubber stoppers provides the reliability needed for both small‑scale research and larger commercial operations. The reusable nature of the components helps reduce material costs while maintaining consistent quality across batches.

What warranty does Zonon offer on this product?

Zonon provides a one‑year limited warranty covering manufacturing defects for both the filter discs and rubber stoppers. If any component fails under normal use within this period, customers can contact our support team for a replacement or refund, subject to verification of the issue.
