## Overview

The Kontes 422530-0050 TLC Reagent Sprayer features a 50mL capacity and a robust 19/22 screw thread ground joint designed for secure, leak-proof connections. It operates efficiently at ultra-low air pressures (1-5 psi), ensuring precise reagent application with minimal waste. Its unique loosening ring mechanism prevents joint freezing from crystallization, making maintenance and autoclaving hassle-free. Lightweight and compact, this sprayer is engineered for professional labs demanding reliability and ease of use.

## Description

The connection between the sprayer head and the flask is made with a special screw thread ground joint, connecting cap and loosening ring. If the joint ever "freezes" from reagent crystallization or residue formation, simply unscrew the connecting cap back onto the unique loosening ring and the joint will easily come apart. These sprayers will operate on as little as 1 psi (0.07 kg/cm²) air pressure with optimal results at 3-5 psi (0.21-0.35 kg/cm²). The connecting cap, loosening ring and o-ring should be removed before autoclaving.
