Gallons upon gallons of tap water are poured down the drain as the common, siphon-style, pipet washers fill then drain repeatedly. When washing is complete, rinsing generally begins using deionized (DI) water – a very expensive solvent. After the time-consuming process of washing and rinsing, the pipets must be carefully removed, sorted into drying baskets and placed in an oven overnight. Total elapsed time to wash and dry a single load of pipets — more than 24 hours.
Tapping into our experience of designing and manufacturing laboratory glassware washers, we decided to address this issue. Combining direct injection cleaning, scrubbing action of percolation and consistency of automation, we streamlined the washing process with considerably less water and substantially less time.
The new ScrubAir™ Pipet Washer/Dryer is a one-of-a-kind automated unit to wash and dry in one place. The durable, steel-constructed unit can wash, rinse and dry up to 60 pipets with just the touch of a button. And it reduces water usage to as little as 10L for wash and rinse versus the 400L (at 2L/min) easily required for four hours of manual washing. At the completion of the wash and rinse cycles, forced-air drying is initiated through direct injection. Total elapsed time to wash and dry a load of pipets with the ScrubAir — just under five hours. This drops to 3.5 hours with the heated model.
The user-friendly interface has three flexible and lockable program cycles including options for both wash and dry duration and number of rinse cycles. The standard model is equipped with a single water inlet and pressurized air inlet. The heated model has an additional water inlet built in, giving the user the added ability to rinse with purified water.
A previously labor-intensive, time-consuming and overall environmentally unfriendly process has been transformed into a fast, simple, environmentally friendly one. Users no longer need to babysit their pipettes. Press a button, walk away, and let the ScrubAir do the work.
