These bottles have a squeeze-bulb dropper attached to the lid.

Amber bottles are good for light-sensitive contents.

Also known as basters, these dispensers transfer larger amounts of liquid than bulb droppers. Liquids are dispensed in a stream, rather than drop by drop. These dispensers are two pieces, so you can remove the bulb for easy cleaning.

Plastic dispensers resist shattering and denting from impact better than glass and stainless steel dispensers. Stainless steel dispensers are more durable than plastic and glass dispensers. They also withstand high heat. Tempered glass dispensers resist staining better than plastic dispensers. They also withstand high heat.

Clear and semi-clear dispensers let you see the liquid inside and confirm the exact volume, unlike silver dispensers.

Dispensers with an injector tip can puncture through a surface to dispense liquid on the inside.

Dispensers with a flat-top bulb can rest standing up to prevent dripping between uses.

Transfer measured streams of liquid.

Bulb pipettes require two hands.

Plunger pipettes can be used with one hand. Turn the thumbwheel to draw liquid into the pipette, then press the plunger for quick dispensing.

Pair these pipettes with a pipette pump to transfer measured streams of liquid. Each pipette has a color-coded band that indicates capacity so you can quickly differentiate one from the next.

Plastic pipettes have a filter to protect their pump from aerosol and splash contamination. Pipette filters are especially important when working with acids and corrosive solutions. Borosilicate and soda-lime glass pipettes withstand cleaning chemicals, so you can sterilize them for repeated use. They provide a clearer view over time than plastic pipettes because samples won't stain them. Soda-lime glass pipettes have extremely tight tolerances to dispense the same amount of liquid each time, keeping your measurements precise. Choose a pipette based on the capacity you need to dispense.

Pipettes with graduation marks let you accurately measure samples of various sizes with a single pipette.

Dispense a sample many times without refilling your pipettor. These tips are designed for use with repeat dispensing pipettors. Like syringes, they have a piston that presses directly against the liquid inside the tip. This creates more pressure than traditional pipettors, which use air displacement, so these tips are good for dispensing thick or foamy liquids.
