Muromachi Kikai Model TMW-4012C (10kW) Microwave Fixation System - 644 hours

AdID: 10179

Availability: In stock


The Muromachi microwave fixation system allows for neurochemical analysis of rodent brains by inactivating enzymes that would be destroyed by alternative methods, for post-mortem dissections. The fixed radiation rapidly heats the brain to 75-90°C in a reproducible procedure that is safe for inexperienced users to perform. Levels of various proteins and metabolites in the brain can be preserved and analyzed by researchers for a variety of biological, pharmaceutical, and biochemical applications.

Condition Description
This instrument is in good cosmetic condition with minimal signs of physical wear and age.

Technical Evaluation
New Life Scientific staff tested this instrument using a container of water, because dry-runs are not recommended and we do not test on animals. Technicians connected the instrument wiring to the electrical box and supplied the correct water flow to cool the instrument, before powering it on. The manual recommends 60 minutes standby while the instrument warms up (preheating) while the cooling system runs. The adjustable exposure timer only illuminates during processing, but can be set in standby. The manual outlines the maximum and minimum output that ensures microwave exposure is controlled.

The technicians prepared a vial of water at room temperature and, unfortunately, tipped the sealed vessel over the chamber. The sample was given a dose of 9 kW for 2.9X seconds and burst open. NLS can confirm that the instrument is working, but no other tests were performed. The vial was removed from the chamber and cleaned. Any remaining water and previous-use residue were discarded.
