Operon's Combination type freeze dryer(Lyophilizer) and All-in-one type freeze dryer. The Cooled & Heated drying chamber and T-type manifold can be loaded samples with vials & flasks and Bulk simultaneously. It is very useful to drying for small quantity of samples.
Operon's bulk tray type freeze dryer(Lyophilizer) applied International patents registered the Cryogenic Auto Cascade systems. And realized the fast cooling & defrosting systems applied the Cryogenic technology. The Lowest temperature -120 degree C of cold trap collectable for almost kinds of vapors even organic solvents like ethanol and protect the vacuum pump.
The primary use of Ammonium Sulphate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of Ammonium Sulphate is its low nitrogen content relative to Ammonium Nitrate, which elevates transportation costs. It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate and glufosinate herbicides.
