The silicone bottle holder helps to stabilize bottles during such laboratory activities such as dispensing liquids with bottle mounted dispensers or connection caps, pipetting or filtration. The centre of mass of the laboratory glass bottle is set centrally in the bottle holder, so you can work comfortably and safely. The bottle is held securely in the holder by eight flexible ribs, making it suitable for use with all round and square bottles that have a diameter/edge length of approx. 75 – 120 mm. In addition, the holder can be used for holding other laboratory glassware, such as tall and low beakers or filtration flasks.
