Introduction
The use of microwaves is a common approach to decreasing reaction times in organic synthesis. In particular, reactions times using Pd, Pt or other metal catalysts can be reduced significantly. Using vials optimised for such conditions allows reactions to be performed at temperatures above the boiling point of the solvent used – this cannot be performed using standard reaction devices, e.g. under reflux.
Quality
KX Microwave Reaction Vials from Kinesis are the high quality cost effective alternative for use with compatible systems. KX Microwave Reaction Vials can be used at temperatures of up to 300°C2 and a working pressure of up to 30bar (even over extended reaction times). All KX Microwave Reaction Vials are manufactured from high quality glass which does not contaminate reaction mixtures.
Re-sealable Silicone/PTFE Crimp Caps
The use of re-sealable silicone/PTFE septa allows the multiple addition of reagents and sampling to monitor reaction progress (whilst maintaining sealed reaction conditions). All KX Microwave Reaction Vials are supplied with 20mm crimp caps; additional crimp caps are available in a cost effective pk/1000.

Stirrer Bars
Kinesis offer stirrer bars for all KX Microwave Reaction Vials. The PTFE coated stirrer bars ensure a homogeneous reaction mixture, ensuring reactions are driven to completion in the minimum time.
Crimping and Decapping Options
Kinesis offers tools for crimping and decapping KX Microwave Reaction Vials. The crimping tool is fully compatible with KX Microwave Reaction Vials, providing securely crimped vials.
