Amber bottles are good for light-sensitive contents.

Style G beakers have a lip to help prevent spills.

These beakers stand up to the most aggressive chemicals.

Style B can be used on a hot plate.

Precisely measure and pour liquids.

Style B have a polyethylene bumper to prevent the cylinder from breaking if tipped over. Remove the bumper when heating or autoclaving the cylinder.

Style C have graduations that can be read from the top down and from the bottom up.

Also known as volumetric flasks, these have a wide base and long neck for fast mixing. A fill line indicates the capacity. Remove lids before autoclaving.

Collect and transfer acids, solvents, and other harsh chemicals. The bowl and handle on these dippers are PTFE, so they resist chemicals better than standard plastic dippers. For added durability, the handle has a stainless steel core. The threaded design lets you detach the bowl from the handle for easy cleaning and storage. To make the dipper longer, thread together as many extension handles (sold separately) as you need to reach your desired length.

Cleaned and individually bagged, these dippers reduce the risk of cross-contaminating samples. Use them to scoop and transfer liquid, then dispose of them when done. The hook end lets you stage them on the side of your tank or vessel, so they’re there when you need them. Thread on the lid to seal your sample and snap off the handle to use these dippers as containers.

To prevent contaminating samples, these samplers are sterilized by gamma irradiation and individually bagged. Throw them away after you collect and transfer liquid to avoid cross contamination.

Insert Style A samplers into the liquid and seal the top opening with your thumb to collect a sample—like a straw.
