Chemistry Laboratory (化學實驗室)(Room 411)
Location: 4th floor, Chan Sui Ki (La Salle) College
This is a special designed room equipped with different kinds of facilities, equipment, apparatus and materials for teaching Chemistry. In the Chemistry Laboratory, students may either perform experiments by themselves or watch demonstrations conducted by their teachers during the practical lessons.
It has been operating since the opening of the school. In order to fulfill the increasing safety demands and to keep the laboratory in good condition, improvement projects and repairing works were done from time to time. In mid 80s, were electric sockets added in each bench. In early 90s, the more safe fibre type bench tops were used to replace all the asbestos lining bench tops and new gas pipe system replaced the old damage one. Besides, the fume cupboards had some major repairing. New exhaust fans were installed and new exhaust ducts were built from the fume cupboards extended upward to the roof of the school building. In mid 90s, catchpot recovery traps replaced the open type dilution tanks to improve the drainage system. In 2001, air conditioners and multi-media projector were installed.

From June 2002 to August 2002, the Chemistry Laboratory had undergone a major renovation. All the facilities and fixtures were dismantled. A newly designed laboratory up to 2000 standard was constructed again.

Now, the Chemistry Laboratory has two efficient fume cupboards, an eye wash station, one teacher bench and six student benches with electricity, water and gas supply. There are enough concrete cupboards and wooden cupboards providing sufficient storage space as well.
Biology Laboratory (生物實驗室)(Room 413)
Location: 4th floor, Chan Sui Ki (La Salle) College

The biology laboratory has been put into use since 1970, several months after the opening of Chan Sui Ki (La Salle) College. While all the other laboratories have been renewed and transformed recently, the biology laboratory remains almost unchanged for thirty three years because the government cuts budget and thus stops the renewal of the biology laboratory.
Accompanying our old laboratory are the thirty-four-year old microscopes, most of which have moulds growing on lenses. However, we are glad to have a projector and screen installed for I.T. purposes. Many more models and specimens are put inside the glass cabinets, and many more new instruments are added for experiments and field work.
