O. Berk has introduced heavy-duty amber laboratory bottles, which according to the manufacturer, are suitable for storage and handling of viscous liquids such as cough syrup or concentrated flavours.

The bottles are protected from unauthorised opening, thus keeping contents safe. They are available in 13 different volumes, ranging from 30ml to 1-litre and can all be equipped with interchangeable closures.

Self-adhesive labels adhere to their smooth glass surface, allowing easy identification of the contents. According to the company, the bottles are durable enough to withstand frequent use. Moreover, the large 1-litre bottles are easy to handle, since they weigh 605g, with a diameter of 96.5mm and a height of 225.1mm.
