Properties of plastic laboratory equipment

The presented plastic laboratory equipment comes from imports. They are characterized by high-quality raw materials and a wide range of uses. Our foreign supplier has an ISO 9001 quality assurance system.

The advantages of plastic devices: they are not fragile, light in weight, easy to clean, do not corrode, surface binding of trace elements and ion exchange is much smaller than on a glass surface.

Fluorinated hydrocarbon-based, Teflon-like plastics approach glass in terms of chemical and heat resistance.
Other physical properties vary greatly. The conditions of use - exposure time and concentration of chemicals, temperature, possible sterilization, exposure to force, aging due to UV radiation, cleaning agents or other environmental influences - significantly determine which plastic is the most suitable for the given area of ​​use.

We would like to help you with the selection with the table below.

Notes

• Plastic dishes should not be cleaned with abrasive abrasives, instead use a sponge soaked in a slightly alkaline detergent.
• Soak the dishes in water with detergent at room temperature for 20-30 minutes. Then rinse the devices with running water and then with distilled water. We can also use an ultrasonic water bath for washing.
• For machine washing, use a maximum 60°C program and weakly alkaline detergent. Polystyrene (PS) dishes can only be cleaned by hand.
• For the analysis of trace elements, the container can be soaked in 1N hydrochloric or nitric acid.
• If disinfection is necessary, the sterilization form can be selected with the help of the table.
