PP 5/10/20/50/60ML Disposable Single Use Light-shielded Light-proof Dispensing Syringes with Needle

In modern clinical medicine, laboratory R&D, and industrial precision dispensing, many photosensitive chemical substances are highly susceptible to photodegradation (such as oxidation, discoloration, or precipitation) when exposed to ultraviolet (UV) and visible light. This exposure can lead to reduced efficacy or even potential toxicity. The PP 5/10/20/50/60ML Disposable Single Use Light-shielded Light-proof Dispensing Syringes with Needle are specifically engineered to solve these points. Made from high-quality Polypropylene (PP) and infused with advanced imported light-blocking agents, these syringes provide excellent shielding to ensure the absolute safety and stability of photosensitive liquids or colloids during extraction, compounding, and delivery.

Product  Advantages

• High-Efficiency Photoprotection (Shielding Rate $ge$ 90%): The syringe barrel incorporates professional light-shielding technology to efficiently block harmful UV rays and short-wave visible light, preventing photodegradation and preserving the original bioactivity of the contents.

• Semi-Transparent Design for Accurate Reading: Despite its superior light-blocking capability, the barrel is structurally optimized so operators can easily observe the liquid level, check for bubbles, and read the graduation marks clearly under normal light.

• Excellent Leak-Proof Performance & Smooth Plunger Motion: The precision-designed medical-grade rubber stopper fits tightly against the inner wall of the barrel, providing a high seal while maintaining low friction for smooth dispensing or aspiration.

• Comprehensive Range of Sizes: Available in popular volumes ranging from 5ml to 60ml, compatible with various dispensing or compounding needles to satisfy diverse application scenarios.

• Ethylene Oxide (EO) Sterilized: Individually blister-packed and EO-sterilized for medical safety, effectively preventing cross-contamination and ready for immediate use.

Material Distinctions & Selection: PP vs. Other Materials

When selecting light-proof syringes, the choice of material dictates chemical compatibility and cost-effectiveness:

• Polypropylene (PP): Features exceptional chemical resistance against acids, bases, and most organic solvents. It is lightweight, shatterproof, and highly cost-effective, making it the most balanced and versatile choice for clinical preparation and industrial adhesive dispensing (such as UV glues and epoxies).

• Glass Material: Offers ultra-high purity and chemically inert characteristics, ideal for specialized long-term laboratory analysis. However, it is fragile, expensive, and impractical for high-volume, single-use disposable workflows.

Primary Applications & Target Audience

• Clinical Medical & Compounding Pharmacies (IVAS/PIVAS): Ideal for nurses and pharmacists preparing, aspirating, or administering light-sensitive medications such as chemotherapy drugs, vitamins (B-complex, Vitamin C), sodium nitroprusside, and antibiotics that decompose easily upon light exposure.

• Industrial Precision Dispensing: Perfect for technicians in electronics, semiconductors, and photovoltaic manufacturing for filling and dispensing highly sensitive UV-curable adhesives, photoresists, silver paste, and epoxies.

• Scientific Research & Labs: Essential for researchers and scientists handling, measuring, or aliquoting photosensitive chemical reagents, biological samples, and fluorescent dyes.

Frequently Asked Questions (FAQ)

Q1: Since the syringe is light-proof, how can I see the graduation marks and the liquid inside?

A: The syringe utilizes a specialized amber or tinted semi-transparent polymer. While it successfully filters out wavelengths harmful to the fluid, it still allows enough ambient light to pass through so the user can easily read the scale and inspect for air bubbles against ordinary light.

Q2: Can these syringes be reused?

A: As indicated by "Disposable Single Use," these syringes are strictly designed for one-time applications. Reusing them may lead to a decline in sealing integrity, degradation of the light-blocking efficacy, or severe cross-contamination.
