Benefits of the PELCO BioWave® Pro System

Superior Microwave Process Control - True Power™
True Power™, not pulsed or percentage power, has made live cell labeling possible. Continuous power outputs from 100 to 750W are programmable.
Superior Microwave Process Control – PELCO ColdSpot® Technology
The PELCO ColdSpot® technology removed the cooking attributes associated with other laboratory microwave devices. Gentle heating has replaced rapid heating to insure precise process control.
Programmed Processing
Pre-programmed protocols are supplied with the system making it the perfect microwave device for multi-user facilities.
True Ease of Operation
True Power™, ColdSpot technology and programmability provide the tools to make microwave processing easier than conventional methods.
Processing Results Based on 2 Decades of Development Experience
The recent microwave literature is a testament to the soundness of our technology and the validity of the scientific approach we took for microwave processing.
Reduced Turnaround Times
Tissue processing for electron microscopy: <45 minutes
Immunolabeling (fluorescent): <40 minutes for 1° and 2° antibodies (Ab)  
Immunolabeling (chromagen): <60 minutes for 1°, 2° Ab's and 3° step
Decalcification with EDTA: >5-fold time reduction
Formalin fixation: <1-hour to achieve the fixation of 24 hours
Tissue processing for paraffin: <1.25 hours for tissues 2mm thick

Gentle Processing

Control of the microwave environment to include temperature, power, uniformity and sample heating rate has made it possible for Ted Pella, Inc. to:

  1. develop the first laboratory microwave to label living cells and embryos
  2. develop the first automated microwave system to rapidly decalcify bone
  3. develop the first automated microwave system to fix fresh tissue in formalin
  4. develop the most versatile laboratory microwave on the market today
