Made of LDPE (low density polyethylene), these wash bottles will withstand most aqueous solutions and weaker solvents. Caps are leak proof with tight threading. Plastic tip is removable so stream volume may be adjusted. There are four sizes in this set:

125ml (4oz)
250ml (8oz)
500ml (16oz)
and 1000ml (32oz)

Wash bottles are indispensible for day-to-day use in labs and many other productions. Many people have purchased these for use in a garage, for instance. Caps are leakproof with tight threading. They are perfect for using to wash out your pet’s ears with a peroxide and alcohol solution. My son recently used one to drink after he had his wisdom teeth out!
