Miniature Light Bulb Changers
Replace hard-to-grip miniature bulbs in equipment such as panels, instruments, indicators, and signs. Install new bulbs without leaving behind oil from your fingers that can cause bulbs to burn out.
Style A are rubber for a good grip on bulbs. Use one end for bulbs between 1/4" and 3/8” dia.; use the other end for 3/4” to 1” dia. bulbs.

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).
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 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.

Electronic Pipette Pumps
Pipette for hours on end—these ergonomic pipettors maintain even flow with just the push of a button. With a set speed, you can carefully monitor the quantities aspirated and dispensed. Choose from six aspirating and dispensing speeds—dispense as fast as 5 ml per second. Choose a higher speed when working with viscous liquids. An LED display shows your speed and battery status. To ensure contamination-free pipetting, the nose on these pumps is autoclavable.

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.

Bulb Droppers
Squeeze the bulb to dispense liquids one drop at a time. These droppers are also known as transfer pipettes.
Removable bulb droppers are easy to clean.
Soda-lime glass droppers are easier to see through than plastic droppers, and they’re less likely to stain. They withstand chemicals, so you can sterilize them for repeated use.
