Pipettor Holders
Store pipettors to keep your lab organized. These holders keep pipettors upright, preventing liquid from running upward—which can cause damage.
Rotating holders maximize pipettor storage while keeping a slim footprint on your tabletop.
Holders with three storage bins have built-in space for storing pipettor tips and other accessories.
Clamp-on-mount holders come with two extenders for a total capacity of three pipettors. Add more extenders (sold separately) for even greater capacity.

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.

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.

Sharps Holders for Syringe Needles and Syringes

Rest needles and syringes with needles in the upright position. The foam insert securely holds sharps in place. These holders have an adhesive back you can attach to a tabletop so they don’t get knocked over. They’re intended for a single use.
Syringe Loading Tanks

Fill syringes quickly without the mess—these tanks use compressed air to push viscous liquid into a syringe. They hold up to a gallon of material, so you can fill many syringes one after another. To fill a syringe, connect a compressed air source to the tank, twist a syringe onto the dispenser, and slowly turn the ball valve. If you’re using a manually powered syringe, check first to make sure the plunger is fully depressed. For air powered ones, check that the stopper is fully inserted.
Monitor the tank’s pressure with a built-in gauge. An included regulator works to hold the tank pressure around the recommended 100 psi. If the pressure gets too high, pull the tab on the release valve. To prolong the life of the material in your tank, you should release the pressure after filling your last syringe. These tanks cannot be sold to Canada due to safety regulations.
