The LW Scientific i4 modular series binocular and trinocular head microscopes feature exceptional optical quality and expandability for top-notch performance in the lab – and USA electronics. Use the rotating head to adjust the height for taller users. The i4 microscope provides comfort, durability, dependability and superior imaging for the lifetime of the laboratory. Living micro-organisms and protists easily come into view with the LW Scientific phase contrast system. The system alters the path of transmitted light to make transparent objects easy to see, providing for excellent contrast and interior cell structure detail not possible under normal bright-field microscopy. It is perfect for use in wastewater treatment applications.
