Employing microwave technology in your laboratory, especially in Histology labs, is a simple process and will improve your operation on multiple levels. Whether you become an all-microwave lab or add microwave processing for stats, overflow, special stains and/or myriad other applications, you will find this line of laboratory microwaves to be the most efficient and versatile tool in your lab.

Benefits

  • Fix, Process, Stain, and Decalcify tissue, in a fraction of the time of any other method or Microwave Processor
  • Provide greater throughput than any other Microwave processor on the market for samples up to 3mm
  • Reduce reagent use
  • Eliminate the need for Xylene in your processing
  • Allow a 50% reduction in your use of Xylene and Alcohol for H&E staining
  • Open the door to using many safe and environmentally friendly alternative fixatives and clearing agents
  • Provide an opportunity to drastically improve the quality of your fatty tissue processing
  • Will not reduce slide quality
  • Will not damage or degrade specimen antigenicity
  • Does not adversely impact IHC or molecular downstream testing
  • Speeds up laboratory workflow

Time and Cost Savings

Automation does not necessarily equal speed. Microwaves process tissue far more efficiently and cost-effectively than any other Tissue Processor. These are the fastest Processors on the market.

  • Reagent used is directly proportional to the volume of samples being processed
  • Xylene Free: use only Alcohols and Paraffin to process tissue with no Xylene clearing steps required
  • Process 74 biopsies in < 20 minutes. No other Tissue Processor even comes close.
  • Patented Polar Heat Sheets allow ultra-fast Microwave paraffin infiltration
