Bottle-Top Dispensers

Often used in laboratories, these dispensers fit on most lab bottles. Push down on the top to dispense precise amounts of acids, solvents, and other liquids.

Burettes with Digital Readout

Reduce errors and increase accuracy--these burettes have a digital readout, so you don't have to calculate how much liquid you've dispensed. Often used when you aren't sure how much liquid you need to dispense, such as in titration, these burettes release liquid drop by drop. Turn the precision knobs on the side to lower the plunger and dispense your liquid. To draw liquid in, turn the knobs in the opposite direction. The burette detects your turn direction, so it only displays the volume you’ve dispensed, not the volume you’ve drawn in. You can adjust the titrating tube vertically and horizontally to fit different bottle sizes or if you need to make room for an additional instrument, such as a magnetic stirrer. Easily take them apart to clean, change inspection windows, and replace batteries.

They come with both clear and amber inspection windows. Use the amber window to protect UV-sensitive liquids. To fit on some of the most common laboratory bottles, they also come with thread adapters.

Burettes with an RS-232 communication protocol can transmit data to your PC with the included USB cable.

Electronic Adjustable-Volume Pipettors

Pipettor

Charging Stand with Pipettors (Sold Separately)

Switch between transferring liquids, mixing samples, and separating mixtures with the touch of a button. Compared to manual pipettors, these pipettors dispense using a motor to improve accuracy and reduce fatigue. Their shape is designed for a comfortable one-handed grip, and the finger rest adjusts so you can fine-tune your grasp. Dispense up to 4,000 times on a single charge.

Select the dispensing volume and function using the screen and buttons. You can control the dispensing speed for better dispensing of thick and foamy samples. These pipettors use air displacement to draw in and dispense in precise amounts. They’re color-coded to quickly identify their volume. Use with universal-fit pipette tips. Press the ejector button to dispose of the tip without touching it.

Add a charging stand to recharge batteries when the pipettors aren’t in use. This keeps the pipettors within reach but stored upright to keep your space organized.
