A range of cleansers, for machine washing and rinsing, that have been developed to meet the cleaning requirements for glassware and small equipment in the laboratory.

• Prevents carry-over of residues to the next analysis
• Chlorine-free

These products have been developed with leading instrument manufacturers for their suitability for washing machines. Extran® products have been tested extensively for their effectiveness and low degree of foaming. It is advisable to neutralise alkaline cleansers with an acid rinse subsequent to the cleaning process. Alkaline cleansers, except Extran® AP 13, do not contain surfactants.

The manual cleansers are provided as concentrates and the cleaning solutions are simply made up with tap water. Typically immersion for up to 2 hours is sufficient, but for particularly difficult residues the time period can be extended. Alternatively, warming the solution or use with an ultrasonic bath can speed up the process. To ensure no residues are left, the user can rinse initially with tap water and finally with distilled or demineralised water.
