Economical, durable and gentle all-plastic washer for delicate glass or quartz cuvettes.

• Mouth of an inverted cuvette is pressed against the rubber cushion to induce suction
• Water or other cleaning fluid poured into the 89 mm (3½") Ø funnel is forcibly sprayed into the cuvette and then drains into the flask
• Continued pressure on the cuvette creates an air flow which dries it
• Final wash in acetone aids in removing water droplets
• Minimum cuvette Int.Ø must be 9 mm or larger to form a seal over the spray nozzle

As long as the cuvette maintains pressure against the cushion, the continued force sets up a stream of air flow into the cuvette and drys it thoroughly. Any residual water droplets may be removed with a final rinse with acetone.
