Potter-Precision Laboratory Spray Tower

Manual Load

Auto-Load


Summary

This air operated spraying apparatus applies an even deposit of spray over a circular area of 9cm diameter. Suitable for studying the biological effects of chemicals both when applied as direct spray on organisms or as a residual film. The towers incorporate developments from Rothamsted Experimental Station.

The automatic safety load-unload system allows operators to place petri dishes on the spray table away from the spray tube and therefore avoids the risk of contamination with hazardous materials. This design offers a smoother elevation of the table and prevents the air from passing to the atomiser until the table is finally positioned. The automatic operating cycle enables increases in processing speeds.

Features

  • Proven reliability
  • Increased safety
  • Manual or autoload versions
  • Robust construction
  • Smooth pneumatic cycle
  • Easy clean all-stainless-steel design

Product Details

The Potter Tower is internationally recognised as the standard of reference for chemical spraying techniques in the laboratory. This type of apparatus is required for studying the biological effects of contact poisons on organisms.

Two models are manufactured by Burkard Scientific at Uxbridge - the standard version and more recently, a model with a safety automatic load/unload facility. Each instrument has similar spray performance characteristics and is designed to apply precise and uniform deposits of spray over a circular area of 9cm (3.54") diameter.

The Tower incorporates developments from the Rothamsted Experimental Station (AFRC - Harpenden, Herts, England) and includes quickly detachable atomizers and a pneumatically operated spray table, with all controls mounted conveniently at the front. A 0-2.5 BAR 10cm/4in.dia. 0-30 lb/sq in, pressure gauge is fitted as standard. A laboratory scale compressor unit and a manometer are also offered as optional equipment.

Throughout industry and research there are increased tighter controls on the handling and use of pesticides both in the field and the laboratory. Mindful of this trend and the potential for operator exposure and contamination in Potter Tower tests for pesticides. Burkard Scientific have introduced an auto-load system.

The load-unload pneumatic option for the Potter Tower eliminates the need for operators to manually place petri dishes on the spray table immediately beneath the spray tube and therefore avoids the risk of contamination. With an automatic operating cycle and the pneumatic on/off switch mounted outside of the fume cupboard loading and unloading of petri dishes can now be made well clear of harmful pesticides. This design offers a smoother elevation of the table and prevents the air from passing to the atomizer until the table is finally positioned. The tower is manufactured from an attractively finished high grade of stainless steel.
