Glass Dropper Pipette 6

Product Code : SCL-LG-12007

The Glass Dropper Pipette 6-Inch is a slender, tapered glass tube paired with a flexible rubber bulb used for suctioning, transferring, and dispensing small, precise quantities of liquid reagents. Specially designed for laboratory technicians, medical researchers, and students, this essential instrument allows for controlled, drop-by-drop liquid delivery across various scientific experimentation setups.

Product Description

The Glass Dropper Pipette 6-Inch from Science Lab Supplies provides outstanding accuracy and dependability for manual fluid dispensing operations. Fabricated from high-clarity Borosilicate 3.3 glass, this dropper features excellent resistance to thermal shock and corrosive chemicals. Its precision-tapered nozzle minimizes fluid retention, ensuring clean droplet formation without leakage or sputtering during critical chemical assays or clinical testing protocols.

This heavy-duty dropper pipette is built to withstand rigorous, everyday use in active scientific environments. Equipped with a removable, resilient rubber bulb that provides excellent suction control, it serves as an eco-friendly alternative to disposable plastic transfer droppers. As a cornerstone item within our premium laboratory glassware catalog, this reusable pipette represents a cost-effective solution for schools, universities, and industrial testing facilities.

Key Features

• Premium Borosilicate Glass: Crafted from low-expansion glass that offers excellent chemical resistance against aggressive acids, bases, and common solvents.
• Ergonomic Rubber Bulb: Features a high-flexibility, removable rubber cap that ensures strong vacuum generation and comfortable suction control.
• Precision-Tapered Tip: The nozzle is expertly fire-polished to ensure uniform drop distribution and prevent unexpected liquid dripping.
• Optimal 6-Inch Length: The 150 mm barrel design allows for easy reach into standard test tubes, small beakers, and narrow-necked media bottles.
• Thermal Shock Resistance: The glass tube safely tolerates dry heat sterilization or steam autoclaving up to 140°C when separated from the bulb.
• Excellent Fluid Visibility: High transparency allows operators to instantly verify liquid levels and check for trapped air bubbles or particulate matter.

How to Use the Glass Dropper Pipette 6-Inch

1. Inspect the glass tube, tapered tip, and rubber bulb for any cracks, splits, or mechanical damage before beginning operations.
2. Push the open end of the rubber bulb firmly onto the top rim of the glass pipette tube to create an airtight seal.
3. Squeeze the rubber bulb between your thumb and forefinger to expel internal air before submerging the tip into the target liquid.
4. Insert the tapered nozzle into the fluid and slowly release your finger pressure on the bulb to draw liquid up into the glass barrel.
5. Position the pipette vertically over the receiving vessel and gently press the bulb to deliver the liquid drop-by-drop as required.

Handling Note: Never turn the filled pipette upside down or completely horizontal. Allowing liquids to flow inside the rubber bulb can cause chemical degradation or cross-contamination.

Care & Maintenance

• Immediate Cleaning: Separate the rubber bulb from the glass tube immediately after use and flush the internal bore with distilled water to prevent chemical drying.
• Soaking and Scrubbing: Soak the glass tubes in a mild laboratory detergent solution and use a fine-wire cleaning brush to clear persistent internal residues.
• Sterilization Prep: Autoclave only the clean glass barrels; the rubber bulbs should be disinfected separately using standard chemical wipes or low-heat sanitization to avoid rubber cracking.
• Safe Storage: Place the dried components horizontally in a compartmentalized storage tray or utility box to shield the fragile glass tips from impact damage.

Frequently Asked Questions

What is a Glass Dropper Pipette 6-Inch used for?

It is used to transfer and dispense small quantities of liquid chemicals or biological stains drop-by-drop. It consists of a 6-inch glass barrel and an elastic top bulb that creates a vacuum to draw and release fluids easily.

What material is this dropper pipette made of?

The tube is constructed from high-quality Borosilicate 3.3 glass for superior chemical and thermal resistance, while the suction cap is manufactured from resilient, flexible natural rubber.

Can the entire glass dropper assembly be autoclaved?

The glass tube component is fully autoclavable and can safely endure high-temperature steam sterilization up to 140°C. However, the rubber bulb must be removed before autoclaving to avoid thermal breakdown.

What is the volume capacity of a single drop?

While this non-graduated pipette is optimized for qualitative, drop-by-drop fluid transfer rather than ultra-precise volumetric measurement, a typical single droplet averages approximately 0.05 mL depending on fluid viscosity.

Can it be used to store chemicals inside bottles?

Yes, this 6-inch dropper is compatible with standard narrow-mouth reagent bottles and can serve as an integrated dropping cap mechanism for common lab reagents or indicator dyes.
