Product Description

I. Overview

Special test paper is a functional paper product used in laboratories for specific substance detection or biological experiments. Manufactured using high-purity filter paper as the substrate through precision impregnation and low-temperature drying processes, ensuring sensitivity, stability, and batch-to-batch consistency.

Key products include:

Ammonia-free Silver Manganese

For rapid ammonia (NH₃) detection. Paper impregnated with silver-manganese indicator, color change upon ammonia exposure. Suitable for environmental monitoring, industrial safety, and lab ammonia leak detection.

Ammonia Detection Sensitive Rapid Color

Seed Germination Paper

For seed germination rate testing and biological experiments. Uniform texture, non-toxic, no optical brighteners, with good water absorbency and air permeability, providing an ideal substrate for seed germination.

Germination Testing No Fluorescence Good Absorbency

We also support custom special test paper development, providing complete solutions from formulation design to production based on your specific detection needs.

II. Core Performance Parameters

Substrate: High-purity filter paper, basis weight 80-100 g/m²
Impregnation: Precision coating, uniform
Drying: Low-temperature vacuum drying (≤ 40℃)
Response Time: 1-5 seconds (varies by product)
Storage: Dark, dry, sealed, 4-30℃
Shelf Life: 12-24 months (sealed)
Optical Brighteners: None (seed germination paper)

III. Material & Workmanship

Manufactured using imported high-purity filter paper as the substrate, with impregnation and drying processes performed in cleanroom environments. Each batch undergoes sensitivity testing and stability testing for batch-to-batch consistency.

Seed germination paper additionally undergoes biocompatibility testing to ensure no inhibition of seed germination.

Selection Guide

I. Ammonia-free Silver Manganese Selection

Application	Recommended Model	Detection Limit
Environmental ammonia monitoring	Standard	≤ 5 ppm
Industrial safety detection	Standard	≤ 5 ppm
Lab ammonia leak detection	High Sensitivity	≤ 1 ppm
Livestock facility ammonia monitoring	Standard	≤ 5 ppm

II. Seed Germination Paper Selection

Application	Recommended Size	Reason
Standard germination testing	100 × 150mm	Most common size
Large-scale seed testing	150 × 200mm	Larger surface area
Special container adaptation	200 × 300mm	Extra large size

💡 Selection Tip: Ammonia-free silver manganese paper is ideal for rapid ammonia detection — standard type for most environmental monitoring, high-sensitivity for low-concentration ammonia detection.
Seed germination paper should match the germination container size — 100 × 150mm is the most commonly used.

Operation & Maintenance

User Guide

Ammonia-free Silver Manganese · Instructions

Take one test strip (use tweezers, avoid hand contact)
Expose the strip to the test environment for 1-3 minutes
Observe color change
Determine ammonia concentration based on color
Discard immediately after use

Seed Germination Paper · Instructions

Cut germination paper to match the germination container size
Thoroughly moisten with distilled or deionized water
Place seeds evenly on the moistened paper
Cover with another layer of paper or maintain in a humid environment
Incubate at optimal temperature (typically 20-30℃)
Monitor and record germination count regularly

General Notes

Special test paper is single-use only
Store in a dry, cool, dark place
Dispose according to laboratory waste regulations after use
For custom test papers, follow the accompanying instructions

💡 Important Notes: Do not touch the test area — hand oils and sweat will affect results.
Store dark, sealed, and dry to prevent indicator degradation or moisture damage.
Read results within 5 minutes — extended exposure may cause color change due to oxidation.

💡 From a Seasoned Lab Technician: "Saturate fully, distribute evenly" — Germination paper must be completely saturated and seeds evenly distributed to avoid stacking that may inhibit germination.
"Humidity is key" — Maintain high humidity during germination — cover with plastic wrap or use a humidity chamber.
"Dark incubation, regular recording" — Most seeds germinate better in dark conditions — record at the same time daily.
