Bulb Dispensers
Bulb with
Clear Stem
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.

Disposable Droppers
Use these glass droppers once and then throw them away to reduce the risk of cross contamination. To control the flow, cover the open top with your thumb.

Pipettes with Pump
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.

Pipettes
Use these pipettes with pipette pumps. For quick identification, they have a color-coded band that indicates capacity. They're made of glass, so they resist chemical absorption.

Pipette Pumps
Draw and dispense liquids at a controlled speed. These pumps give you more control of flow than a basic pipette bulb but not as much as an electronic pump. Use them with a pipette (not included).
Plunger pumps can be used with one hand. Turn the thumbwheel to draw liquid into the pipette then press the plunger for quick dispensing. For gradual dispensing, you can use the thumbwheel.
Bulb pumps have a lever to set both the aspirating and dispensing speeds. Press the button above the lever to blow out any residual liquids.

Pipette Washers
Connect these washers to a water supply to rinse many pipettes efficiently, reliably, and safely. Place pipettes within the carrying basket, which cushions them to prevent breakage. After soaking them, transfer the basket to the rinser. The rinser fills with clean water to wash your pipettes and rapidly siphons out contaminated water to maintain cleanliness. All components are made of polyethylene or polypropylene to withstand common cleaning solutions.

Pipette Bulbs
The simplest form of a pipette pump, these bulbs let you control flow as you quickly draw and dispense liquid. Use them with two hands to ensure they don’t separate from pipettes (not included).
Vinyl plastic bulbs are more chemical resistant than natural rubber bulbs, helping them resist degrading if you accidentally draw chemicals up into them.
Bulbs with control valves are more precise than bulbs without control valves. They have three valves—one empties air from the bulb, one suctions liquid into the pipette, and one empties the pipette.
Pipette Holders
Tabletop Mount
with Drip Tray
Keep your pipettes organized. These holders support pipettes along the middle of their body, minimizing pressure on the tip to reduce wear. Place them on a table- or bench-top for easy access.
Horizontal holders include a drawer insert with slots to hold both short and long pipettes. There are two layers of slots that let you store pipettes perpendicularly to maximize storage capacity.
Vertical holders allow pipettes to drain. Rotating holders let you select the pipette you need without reaching around the holder.

Sterile Reagent Reservoirs
To make sure these reservoirs arrive sterile, they've been irradiated, individually bagged, and marked with a lot number. Use them to hold reagents and samples for easy access during pipetting. A V-shaped bottom helps you collect samples as your liquid starts to run low. All have molded graduation marks, so you can gauge how much liquid is inside. There’s a pour spout on each corner for discarding excess liquid. These reservoirs cannot be autoclaved or reused.

Reagent Reservoirs
Hold reagents and samples for easy access during pipetting. These reservoirs have an angled bottom, so you can collect samples even as your liquid starts to run low.
Rectangular reservoirs have molded graduation marks to see how much liquid is inside. There’s a pour spout on each corner to discard excess liquid.
V-shape reservoirs have a single large reservoir on one side and 8- and 12-chamber reservoirs on the other. Useful for multi-channel pipettors, the smaller chambers reduce the risk of waste. They’re often used to hold different reagents or ratios and for serial dilutions. Made of polypropylene, they can be autoclaved for reuse.
