How To Clean Your Microscopes?

Make sure that you only clean your microscope lenses when they are dirty and use the proper materials!

If your objective lenses are dirty, you can remove build-up with lens paper dipped in a very weak ammonia solution. Place one eye dropper full of household ammonia in 1/2 cup of water.

If you have any sticky substances on your objectives such as balsam, oily materials or paraffin, this should be removed with xylol.

To clean microscope eyepiece lenses, breathe condensation onto them and then wipe them with lens tissue. Kim-wipes are made by Kleenex and generally will work well. For stubborn spots, wipe the surface with tissue moistened with 95% alcohol. Wipe the lens dry with a dry tissue.

If you see black specks when you look through the microscope, turn the eyepiece lens to see if the specks also turn. If so, the dust is on either the inside or outside eyepiece lens. Clean the eyepiece lens with lens tissue. If the spots remain, remove the eyepiece lens and brush the inside of the eyepiece lens with a camel hair brush or lens paper.

DO NOT USE cloth, ordinary paper or fingers! Make sure that you use only special lens cleaning tissues!

Periodically inspect the power cords and plugs for safety and have a supply of replacement bulbs available.

Professional cleaning and adjusting should be performed whenever necessary at an optical shop specializing in microscopes. Usually the microscope manufacturer can recommend a qualified professional that services their microscopes and will not alter the warranty.

When microscopes are not in use, they should be covered with plastic and stored in a safe area where they won't get knocked over or stolen.

Keeping a clean microscope will ensure that you will get many years of quality use out of your microscope!

AliExpress.com & Alibaba.com

As you may know, we sell our product on AliExpress and Alibaba (both "alibaba.com" and "alibaba.com.cn")

Not many people know the differences and the relationships of AliExpress and Alibaba.

When Alibaba Group decided to launch its new global wholesale platform AliExpress.com, many e-commerce experts in China shed doubts on the big move Alibaba was going to take. However, since AliExpress made its official debut in April 2010, all doubts have gradually gone. Today, as a giant in the arena of small wholesale business, AliExpress speaks another huge success of Alibaba.

 

Over the past decade since its inception in 1999, Alibaba.com has established an unbeatably big name on the global market of wholesale trade and almost all merchants know well about Alibaba.com. Comparatively, AliExpress.com may be still a little bit strange to some businesses. If you are looking for orders in small quantities with fast shipment and secure protection, you are encouraged to learn more about AliExpress, right from here.
As the brand name indicates, AliExpress is composed of “Ali + Express”. Yes, from the very beginning, AliExpress is intended to be Alibaba’s express channel for wholesale transactions. We know, Alibaba.com charges membership fees on suppliers and mainly provides information service between sellers and buyers. Different from Alibaba.com, AliExpress.com does not charge any fees on registered members (either suppliers or buyers) and inspects the whole transaction process between the two transaction parties. It’s a wholesale platform targeting small and medium-sized suppliers and buyers. There minimum orders as low as 1 item are accepted and express delivery, in some cases, fast and free shipping is offered. In addition, a vast array of item categories can be found on AliExpress—it truly is a one-stop-shop for small wholesale orders.
