Buying a Secondhand Microscope in Australia

If money is not an issue, opt to buy a brand new microscope, as buying secondhand microscopes in Australia requires you to have an eagle-eye on various factors to ensure it is worth your money. 

Problems of Buying Secondhand Microscopes in Australia

But what if you have a limited budget? Is buying a new microscope still an option? 

If you know where to look, getting your hands on a brand new but affordable microscope is possible and a better option than risking wasting your money on a used microscope that might have the following defects. 

Issues with the objectives 

Some objectives that come with a microscope might not be suitable for the kind of microscopy you want. These objectives can be costly because they require special application. 

Also, the objective lenses could have issues. The most common being that the adhesive that keeps them in place is starting to loosen up. This causes air bubbles to appear, affecting your viewing experience. 

Fungal growth

Fungal growth may also be a problem with secondhand microscopes in Australia if not properly cleaned and cared for, especially if the storage is humid with changing temperature.  

Mechanical defects

Some used microscopes might have mechanical parts missing, while others have parts that are hard to use at all. One example is the knob. If you have trouble turning it easily, it means that the oil that lubricates it has already hardened, making turning it difficult. 

Also, be wary of loose parts and any visible dents or cracks. 

Stage drift

Stage drift means that the stage doesn’t stay in position at all. It makes focusing difficult for the users. 

Faded coatings

Lens coatings are essential because they help improve the microscope’s image quality by enhancing the contrast and eliminating light reflection. But due to the use of wrong cleaners, these coatings may fade and can affect the quality of your viewing.
