Labware brushes are used for the manual cleaning of laboratory glassware and vessels. They are typically sold individually or as sets with different dimensions to allow for effective cleaning of a wide range of vessel sizes.
Bristles are made from a variety of materials, including nylon and silicone. Nylon is the most common, inexpensive, easy to clean, and long-lasting.
Test Tube Brushes
A test tube brush is used for cleaning the bottom of test tubes. These brushes have twisted wire handles with bristles made of Nylon or Tynex.
They are designed to be small enough to fit into a laboratory’s small test tubes and cylinders. This is so they can be more efficient and clean the box without damaging the cylinders or test tube’s inside.
Suitable for test tubes with a diameter of 11 millimeters to 18 millimeters.
They can also be used in aquarium tanks to remove slime and algae from the filter system. These are great tools to have in your lab. They have a twisted wire handle with bristles that are made of Nylon and come in various sizes to suit the different size tubes in a lab.
Beaker Brushes are used to clean various lab glassware types, including beakers, flasks, bottles, and cylinders. They have sturdy bristles that are strong and chemical resistant for cleaning any solutions or solvents.
This black nylon brush with a tufted tip works well for cleaning the bottom of beakers, bottles, and large graduated cylinders. It has a long handle designed to clean thoroughly without scratching the glass.
Laboratory glassware should be cleaned after each use. This can be done with soap, detergent, or a mildly abrasive cleaning powder. It is also best to dry the glassware by hanging it on a wooden peg or placing it in a basket with its mouth down. This prevents dust from getting in the pores of the glassware and is especially important for new labware. Protecting clean glassware from breakage is also important, especially when heated.
Jar brushes are an excellent option for getting into those hard-to-reach spaces in jars, bottles, and mugs. They have an ergonomic, t-shaped handle with durable, long-lasting bristles that won’t crack or break.
To keep laboratory glassware clean, wash it immediately after use. Then, dry it off by hanging it on pegs, placing it in a basket with its mouth down, or putting it in an oven to dry.
If the jar or bottle is too dirty to be cleaned, place it in a cylinder of dissolved detergent or a pot of chromic acid cleaning solution. This will prevent any residue from being left behind on the surface of the glassware.
