After glassware has been washed, it should be dried carefully to avoid introducing any impurities. Drying with paper towels can introduce fibres or dust which could affect high accuracy work.
There are 3 main methods for quickly and cleanly drying lab glassware, each with their own specific benefits and drawbacks.
1. Natural Air drying
When the glassware is not required quickly, natural air drying can offer the simplest solution.
A range of drying or draining racks are available to hang glassware with the open neck facing down – this not only ensures quick drying and draining but also avoids dust from the air getting into the vessels.
Choose a unit with the right number and lengths of drying pegs to suit the glassware you usually work with. Remember to keep the rack clean to avoid introducing any contamination into your glassware.
2. Electric Drying Racks
For faster results but still in a compact unit, an electric glassware dryer can be used. These force warmed air into each piece of glassware, accelerating the drying.
Some models will also come equipped with a timer – this means you can leave the unit running only for as long as needed, saving energy compared to oven dryers.
The gentler heating of these sytems compared to oven or glasswasher drying makes them suitable for most plastic containers as well as glassware.
3. Glasswashers with built in drying
For high throughput laboratories that need glassware turned around quickly, a glasswasher with built in drying is the best option. These will take care of the washing and drying of all glassware, and ensure a clean, pure finish.
The Camlab Cub 4090 models have a built in drying system which filters the air on intake, ensuring the air used is clean. The air is heated and directed over the surface of the glassware, giving extremely fast and efficient drying.
