Description
Product Overview
The 8‑piece thick borosilicate glass dropper set is engineered for professionals who demand accuracy, durability, and environmental responsibility in liquid handling. Each pipette is crafted from high‑grade borosilicate glass, a material renowned for its resistance to thermal shock, chemical corrosion, and mechanical stress. The graduated markings are laser‑etched, providing clear, precise volume indicators ranging from 0.5 ml to 10 ml, which eliminates guesswork and reduces measurement error in critical applications. Silicone caps seal each pipette securely, preventing evaporation and contamination while allowing easy dispensing. The set also includes two soft‑bristle cleaning brushes and two 20 cm glass stir rods, enabling thorough cleaning and reuse without compromising performance. All components are packaged in a compact, lightweight box (9.13 × 2.68 × 1.73 in, 7.2 oz) that fits conveniently on laboratory benches or in field kits. Designed for laboratories, research facilities, and hobbyist workshops, this versatile kit meets the rigorous standards of modern scientific practice while offering a sustainable alternative to disposable plastic pipettes.
Usage
This dropper kit excels in a wide range of environments where precise liquid measurement and transfer are essential. In chemistry labs, the graduated pipettes enable accurate titration, reagent preparation, and sample handling, ensuring reproducible results across experiments. Microbiology researchers rely on the sterile, non‑reactive glass to dispense culture media, antibiotics, and staining solutions without introducing contaminants. Fragrance formulators appreciate the fine control over essential oil volumes, allowing nuanced scent development and batch consistency. The included cleaning brushes and stir rods simplify maintenance: after each use, a quick rinse with appropriate solvents followed by gentle brushing restores the pipettes to pristine condition, ready for the next task. Field technicians benefit from the robust glass and silicone caps, which protect the pipettes from accidental breakage and leakage during transport. Whether you are conducting bench‑top assays, preparing calibration standards, or performing quality‑control checks, this kit provides reliable performance and repeatable accuracy.
Why Choose Us
Choosing this glass dropper set means investing in a product that combines superior material quality with thoughtful design. Borosilicate glass offers unmatched chemical inertness, meaning your samples remain pure and unaltered by the container. The thick‑wall construction adds resilience against accidental drops, extending the lifespan of each pipette far beyond that of thin‑walled alternatives. Our laser‑etched graduations are permanently affixed, resisting wear from repeated cleaning cycles and ensuring long‑term readability. The silicone caps are engineered to fit snugly, providing a leak‑proof seal that protects volatile or hygroscopic liquids. By including reusable cleaning accessories, we reduce plastic waste and lower operational costs for laboratories committed to sustainable practices. Each component undergoes rigorous quality inspection, and we stand behind our product with responsive customer support, offering guidance on proper use, maintenance, and troubleshooting. When you select this kit, you receive a complete, ready‑to‑use solution that aligns with both scientific precision and environmental stewardship.

FAQ
Can these pipettes be used with corrosive chemicals?
Yes. Borosilicate glass is highly resistant to a wide range of acids, bases, and organic solvents. While it tolerates most laboratory chemicals, it is advisable to avoid prolonged exposure to hydrofluoric acid, which can etch glass. Always follow safety guidelines and rinse the pipettes thoroughly after handling aggressive substances.
How do I clean and sterilize the pipettes?
After each use, rinse the pipette with the appropriate solvent (water, ethanol, or another compatible cleaning agent). Use the supplied soft‑bristle brush to remove residues from the interior. For sterilization, autoclave the pipettes at 121 °C for 15 minutes; the thick borosilicate glass tolerates standard autoclave cycles without damage.
What is the accuracy of the graduated markings?
The graduations are calibrated to an accuracy of ±0.02 ml for volumes up to 5 ml and ±0.05 ml for larger volumes. This precision meets the requirements of most analytical and preparative laboratory procedures, providing confidence in quantitative work.
Are the silicone caps compatible with all pipette sizes?
Each cap is sized to fit its corresponding pipette snugly, ensuring a tight seal across the entire range (0.5 ml to 10 ml). The caps are made from medical‑grade silicone, which is chemically inert and does not leach substances into the liquids being handled.
What warranty or support is provided?
We offer a one‑year limited warranty covering manufacturing defects. Our technical support team is available to answer questions about usage, cleaning, and troubleshooting. Replacement parts, such as caps or brushes, can be ordered separately if needed.
