Product Overview
The PP drip peg—also referred to as the drip rack peg, detachable peg, test tube drying peg, or simply lab drying peg—is a replacement component designed for laboratory drip racks. When glassware is washed and inverted on drip racks for drying, the pegs support the vessels while allowing water to drain away. Over time, pegs may become damaged or lost, making replacement pegs essential for maintaining full rack functionality.
EduSupports offers these PP drip pegs manufactured from high-density polypropylene (PP) , the same material used in quality laboratory drip racks. Each peg is 130mm in length, compatible with most standard drip rack systems. The detachable design allows for easy installation and removal—simply insert into the rack’s mounting holes until secure.
Available in grey, black, or white to match existing drip racks or for color-coding different laboratory zones.
Whether you need to replace broken pegs, expand your rack’s capacity, or keep spares on hand for a busy laboratory, EduSupports has the right solution.

Why Choose This PP Drip Peg?
The PP drip peg offers several advantages for laboratory glassware drying applications.
First, its high-density PP construction provides excellent chemical resistance. Unlike ordinary plastic pegs, this material withstands exposure to strong acids, alkalis, and organic solvents commonly found in laboratory environments.
Second, the 130mm length is optimized for standard laboratory glassware. It accommodates test tubes, beakers, flasks, pipettes, and graduated cylinders of various sizes, providing stable support during drying.
Third, the detachable design with locking mechanism ensures secure installation. The peg locks into place once inserted, preventing accidental dislodging when removing glassware. Yet it can be easily removed when replacement is needed.
Fourth, the peg is autoclavable, allowing for sterilization between uses—essential for biological and medical laboratories requiring sterile conditions.
Fifth, pegs are available in grey, black, or white to match existing drip racks or for color-coding different laboratory zones or contamination levels.
