Smoother scale lines on Microscale Slide made of plastic (polystyrene)
The scale line with the accurate linearity that equals with the ones made of glass slides has been achieved. It is possible to put the sample directly on the Micro-scale when observing with the microscope because it is far cheaper than the traditional glass slide.
Note: Please replace with a new slide after using several times and if it is hard to see due to dirt and scratches.
