Get ready for winter with antifreeze that is suitable for your laser tube.
Dilute the LS Coolflow with de-ionised or distilled water at a ratio of 1:4.
Although based on Ethylene Glycol, Laserscript CoolFlow has been tested and classified as Non Toxic by an EPA certified laboratory. Previously Propylene Glycol was the only non toxic glycol available, that is no longer the case. The DeTox® additive. DeTox® prevents Ethylene Glycol from being metabolised (during digestion) into toxic by-products, which cause kidney failure, blindness and death. Tests carried out on CoolFlow confirmed the toxicity was "so low that it was impossible to determine an LD50 value".
The DeTox® additive has very little effect on heat transfer or antifreeze performance. In fact similar volumes of CoolFlow or Ethylene Glycol are required to achieve a specific freeze protection.
