Low density polyethylene with a white polypropylene screw closure. Convenient wide-mouth opening for solids, powders, overhead mixers, the same material benefits as 2210 series carboys, 100mm closure. Low density polyethylene (LDPE) resin is made using less catalyst than HDPE and is a better choice for reagents sensitive to the polymerization catalyst. Graduated to contain in 1 gallon and 5 liter increments. LEAKPROOF.

Graduated cylinders have a "Total Contained, Total Delivered" single scale with raised numerals for easy reading. Flared top rims and large spouts facilitate pouring, and hexagon shaped bases provide stability. The "non-wetting" polypropylene surface eliminates concave meniscus and makes reading easier and more accurate. Chemically resistant and autoclavable at 121ºC (250ºF). Translucent.

Fill the first container to desired level and record fill gauge reading using built-in reference marker. Subsequent containers can be filled until level indicator reaches reference marker. It's that easy to get accurate filling every time! Designed for use with lower viscosity, non-sticky, liquids. Fits any steel drum with a 2" or 3/4" NPS opening. 23" long. Plastic non-threaded 2" adapter included. Adapter allows access of a 1 1/4" hose or pipe, so filling and gauging may be done simultaneously.
