Great question! You’ll see a few common names used for these.

• Transfer pipettes: Soft plastic tubes with a bulb tip you squeeze to release drops, often marked in milliliters.
• Eye droppers: A general term for droppers used to dispense small amounts of liquid.
• Dropper bottles: Refillable plastic bottles (often 2–100 mL) with a thin dispensing tip for controlled dripping.
• Bulb droppers: Pipettes featuring a silicone or rubber bulb at the top.

On our site, product titles may use these terms interchangeably. If you’re looking for precise dosing, check for graduations or sets that include funnels and labels to keep everything organized.

You’ll typically find a range of dropper styles to fit different projects.

• Plastic transfer pipettes (often 5 mL): Flexible, easy to squeeze, good for crafts and small batches.
• Squeezable dropper bottles (about 2–100 mL): Refillable bottles with thin tips for controlled flow.
• Glass dropper bottles (commonly 1 oz or 2 oz): With a screw cap and glass pipette, often in amber or cobalt to help minimize light exposure.
• Roll-on bottles: Refillable bottles with stainless steel rollers, handy for fragrances.
• Child-resistant options: Caps designed to be harder for kids to open.

Many sets also include funnels, measuring cups, and labels for easier filling and organization.

Think about how much liquid you’ll dispense and how often.

• Samples and testing: 2–10 mL bottles or pipettes keep quantities small and precise.
• Everyday crafting or oils: 15–30 mL offers a balance of portability and capacity.
• Larger batches: 1–2 oz bottles reduce refills and are good for routines.

Consider viscosity: thicker liquids benefit from wider tips or squeeze bottles, while thin liquids work well with fine tips. Check for graduation marks or included funnels/measuring cups to help with accurate fills. Leaving a little headspace can reduce leaks when squeezing or traveling.

Basic care can help extend their usefulness, though some pipettes are intended for single use. Here’s a general approach:

1. Rinse immediately with warm water to prevent residue from drying.
2. Wash with mild dish soap; gently squeeze water through tubes and tips.
3. Oil-based liquids: A brief pre-rinse with isopropyl alcohol can help, if compatible with the material.
4. Rinse thoroughly until water runs clear.
5. Air-dry fully, tip down when possible.

Consider dedicating droppers to specific liquids to avoid cross-contamination. If you plan to use droppers for medicines, consult a medical professional for cleaning and dosing guidance. Always review the product description for reuse recommendations.

You’ll find several cap styles designed for convenience and control.

• Leak-resistant screw caps: Help reduce spills when bottles are closed properly.
• Thin-tip dispensing caps: Offer precise drops and often include protective covers.
• Child-resistant caps: Designed to be harder for children to open; they’re helpful but not child-proof.
• Roller-ball tops: Stainless steel rollers for smooth application of fragrances.
• Tamper-evident rings and sealing washers: Provide an extra layer of closure assurance.

For best results, close caps firmly, label contents clearly, and store bottles upright and out of reach of children. Features can vary by set, so check the product details.
