Product Description

I. Overview

The plastic serological pipette is an essential consumable for precise transfer of larger liquid volumes in the laboratory. Manufactured from high-clarity polystyrene (PS) through precision injection molding, featuring transparent body, clear graduations, and smooth inner surface.

Available in 1ml, 2ml, 5ml, 10ml, 25ml, and 50ml sizes, with individual paper-plastic or plastic wrapping for convenient use and contamination prevention. Sterilized by gamma irradiation, sterile pyrogen-free.

Designed for single-use — no cleaning or sterilization required, eliminating cross-contamination risks. Features positive/negative graduations for precise reading and dispensing. Ideal for cell culture, microbiology, molecular biology, and other sterile applications.

🔬 Product Advantages:
High Clarity — Easy viewing of liquid for pipetting accuracy
Individual Wrapping — Ready to use, prevents cross-contamination
Positive/Negative Grad — Supports precise dispensing and blow-out
Sterility Guaranteed — Gamma sterilized, sterile pyrogen-free

II. Core Performance Parameters

Material: High-clarity polystyrene (PS)
Process: Precision injection molding
Spec Range: 1ml ~ 50ml
Packaging: Individually wrapped
Sterilization: Gamma irradiated
Quality: Sterile, pyrogen-free, non-cytotoxic
Graduations: Positive/negative, molded
Compatibility: Electric/manual pipettors

III. Material & Workmanship

Manufactured from medical-grade polystyrene (PS) resin in controlled injection molding environments, ensuring high clarity and dimensional accuracy across all sizes. The tube body is smooth and uniform with clear, easy-to-read graduations.

Features negative graduation design, allowing users to dispense volumes beyond the marked capacity for greater pipetting flexibility. Every batch undergoes rigorous testing to ensure consistent quality.

Selection Guide

I. By Capacity

Pipetting Range	Recommended Size	Typical Application
0.2~1ml	1ml	Micro reagent transfer, standard preparation
0.5~2ml	2ml	Routine liquid transfer, media preparation
1~5ml	5ml	Cell culture addition, buffer transfer
2~10ml	10ml	Large volume transfer, serum dispensing
5~25ml	25ml	Bulk liquid transfer, media dispensing
10~50ml	50ml	Large batch transfer, bioreactor addition

II. By Packaging

Paper-Plastic Wrap: Suitable for sterile applications, easy single-use
Plastic Wrap: More durable, suitable for long-term storage

💡 Selection Tip: 10ml serological pipette is the most commonly used size for routine liquid transfer.
For sterile applications, always choose individually wrapped sterile pipettes.
For large volume transfer (>10ml), choose 25ml or 50ml sizes.

Operation & Maintenance

User Guide

Below are standard operating guidelines for plastic serological pipettes. Proper use ensures pipetting accuracy and experimental reliability.

I. Pre-use Preparation

Inspect packaging integrity and pipette condition
Confirm pipette size matches the required volume
For sterile pipettes, verify sterilization expiry date
Avoid touching the tip and opening during removal from packaging

II. Pipetting Operation

Insert the top of the pipette into the pipettor, ensuring a secure seal
Immerse the tip below the liquid surface and aspirate to the desired volume
Read the graduation with the meniscus at eye level
Dispense by touching the tip against the container wall to reduceresidue
Use the negative graduation area if additional blow-out is needed
Dispose of the used pipette in a sharps or waste container

III. Disposal

Dispose of used pipettes in sharps containers or biohazard waste containers
Pipettes used with biohazardous samples should be disposed according to biosafety regulations
Pipettes used with chemical hazards should be disposed according to chemical waste regulations

💡 From a Seasoned Lab Technician: "Single-use only — never reuse" — Serological pipettes are single-use consumables — reuse leads to cross-contamination.
"Negative graduation is a great feature" — Allows blow-out of excess liquid for greater pipetting flexibility.
"Read with eye level" — Level your eye with the meniscus for accurate reading.
"Follow sterile technique" — When using sterile pipettes, maintain aseptic technique and avoid touching the tip to non-sterile surfaces.
