About this item
Glass Transfer Pipettes. Reliable lab glassware designed for everyday bench use. Built with quality borosilicate glass and precision manufacturing to handle routine lab workflows without fuss. A practical addition to any lab setup.
Essential Liquid Handling with Boro 3.3 Droppers
Every modern laboratory requires highly reliable liquid handling tools. Reliable glass transfer pipettes remain an absolute essential on any workbench. They easily handle aggressive organic solvents daily. Plastic alternatives often melt or leach dangerous plasticizers into your analytical samples. Standard polyethylene fails quickly when exposed to acetone, chloroform, or DMSO. Our premium droppers utilize pure borosilicate glass natively. This high-grade material resists harsh chemical attacks perfectly. It provides the ultimate physical protection for your sensitive extracts.
You can verify official global material testing standards directly at the ASTM International root hub. It prevents false chemical readings in your spectroscopy results entirely. You can move harsh solvents securely without any workflow worries. Pair these reliable tools with our Lab Glassware collection to build a complete chemistry setup today. Our products ensure maximum safety continuously.
1Total Chemical Inertness
Handling concentrated laboratory acids requires extreme caution always. A standard set of glass transfer pipettes ensures absolute safety during liquid transfer tasks. Borosilicate glass will not dissolve or swell over time. It guarantees zero chemical contamination for your precious samples. It is perfect for demanding organic extraction workflows daily.
2Ceramic Fired Graduations
Printed volume marks on cheap plastic often rub off after washing. We solve this annoying issue by firing ceramic ink directly into the glass. These high-contrast graduations survive harsh acid scrubbing easily. The scale remains perfectly visible for years of daily laboratory use. It delivers fast and accurate volume estimations constantly.
3Integrated Bulb Chamber
Precision aliquoting requires excellent fluid suction control natively. This unit features a built-in bulb chamber seamlessly. It offers much better liquid retention than cheap flat-stem models. You simply squeeze the bulb to aspirate and release to hold the fluid. Dispensing chemicals drop-by-drop becomes an incredibly simple manual task.
Core Capabilities of the Glass Droppers
🌡️ Thermal Stability
Safely withstands rapid temperature differentials up to 200°C (392°F). It is perfect for transferring hot reaction reagents securely.
🫧 Autoclave Safe
You can safely autoclave the droppers at 121°C (250°F) repeatedly. It ensures complete sterilization for sensitive biological handling.
⚖️ 4 Capacity Options
We offer four highly practical sizes for your testing bench. Choose from 2ml, 3ml, 5ml, and large 10ml variants safely.
📦 5-Pack Bundles
Each sealed protective box contains five individual pipettes. It keeps your busy laboratory fully stocked very affordably.
Upgrading your liquid handling tools improves data accuracy immediately. Stocking multiple sizes ensures you always have the right dropper ready. Dedicated glass transfer pipettes prevent catastrophic cross-contamination during complex multi-sample runs. They save you from buying expensive volumetric tools unnecessarily. Enhance your daily lab efficiency by exploring our Lab Pipette collection today.
FAQs
Q1: What is the difference between a glass transfer pipette and a graduated pipette?
A1: A glass transfer pipette combines the convenience of a dropper (bulb suction chamber for one-handed operation) with the accuracy of a graduated scale printed directly on the glass body. Traditional graduated pipettes require an external pipette filler or mouth aspiration and are designed primarily for measuring specific volumes before dispensing. The transfer pipette, by contrast, excels at quick aspirate-and-dispense workflows where visual estimation within ±10% tolerance is acceptable — exactly what most routine lab tasks demand.
Q2: Can I use these pipettes with aggressive chemicals like concentrated sulfuric acid?
A2: Yes for brief exposure periods. Borosilicate glass resists concentrated sulfuric acid, nitric acid, and hydrochloric acid indefinitely at room temperature. However, hot concentrated alkalis (e.g., >50% NaOH above 80°C) can etch the glass surface over prolonged contact. For routine acid/base work at ambient temperature, these pipettes perform identically to premium brands like Pyrex or Duran. Rinse thoroughly with deionized water after each use to prevent residue buildup.
Q3: How do I clean and reuse these glass pipettes?
A3: Rinse immediately after use with a compatible solvent (water for aqueous reagents, acetone or ethanol for organics), then wash with laboratory detergent in warm water, rinse thoroughly, and air-dry in a rack. For trace-analysis work, follow with a distilled-water rinse and dry in a clean oven below 150°C. These pipettes survive unlimited cleaning cycles — unlike disposable plastic alternatives that degrade after a few uses, each Huaou glass pipette provides years of service when properly maintained.
Q4: What does "pack of 5" mean — do I get 5 different sizes?
A4: Each SKU represents a single size option containing **five identical pipettes** of that capacity. If you order the “2 ml (5 PCS)” variant, you receive five 2 ml pipettes. To get all four sizes, order each capacity variant separately. This packaging format is standard for lab supply because most labs stock multiple units of their most-used size rather than one unit each of four different sizes. It also reduces per-unit shipping cost and allows you to dedicate separate pipettes to different reagent classes to avoid cross-contamination.
