Common Mistakes In Lab Glass Repair And Their Fixes
Lab glass repair is common in many laboratories. Being aware of what causes these issues and knowing how to fix them is important for laboratory technicians. Here are some of the common issues with lab glass and how they are repaired.
Cracked and Chipped Glass
The most common problem with lab glassware is the cracking or chipping of the material. This can be caused by mishandling or impact on the part of the user or when the product is dropped. When this happens, it's best to take your glassware to a professional for repair instead of trying to do it yourself because you could end up making things worse.
Glass Scratches and Corrosion
Glass scratches easily due to its smoothness, which makes it difficult to clean. You can prevent scratches by using a soft cloth to wipe your glassware, instead of paper towels or rough cloths that can scratch the surface.
When corrosion occurs in lab glass, it appears as a hazy white film on the surface of the glass. This is often caused by exposure to chemicals like alcohols, amines, and acids that cause the oxides on the surface of the glass to dissolve into a solution. The best way to prevent corrosion on your glassware is by cleaning it immediately after use so there is no time for these compounds to react with the oxides on your glassware.
Reaction with Acids or Bases
Acids and bases can cause serious damage if they come into contact with glassware. Acidic fluids can cause etching or pitting on the surface of your glassware while alkaline solutions will leave residue on your equipment and make them difficult to clean properly. If you're cleaning a beaker with acid or base solution, you need to make sure that you rinse it thoroughly before using it again so as not to contaminate your experiment with unwanted residue from the cleaning solution.
Poor Welding of Flasks and Joints
The most common mistake in a lab glass repair is poor welding. Welding can be done with a torch or an electric arc. Both methods are best done by an experienced technician. A poorly welded joint will not withstand the same amount of pressure as a properly done one, leading to leaks and potentially dangerous situations if it breaks under pressure. Therefore, it is best to have these glass repairs professionally done.
Knowing what to do in case of glass repair issues is important for laboratory technicians.
