Quadra Tower is based on the highly reliable Quadra4 technology. Designed to speed up workflows with 8- and 12-channel manual pipettes. The integrated bath allows handpieces to be washed between suction / dispense cycles, saving time and significantly reducing consumable costs. The bath can be converted into an ultrasonic bath with or without a circulating peristaltic pump.
The Quadra Tower is equipped with four pneumatically operated pull-out trays and an integrated air compressor. The Quadra Tower is available with 96 air offset tips or 96/384 forward biased tips. The air-cushion head supports standard 450 µl disposable tips and can dispense up to 10 µl in 3% variation. Four positive bias options support a 96 or 384 tip head with a CV of 2%. The positive displacement heads are based on stationary stainless steel coated handpieces that can be cleaned between workings using an integrated bath.
The Quadra Tower is a low-cost, compact device designed to accelerate a wide variety of aqueous or organic workflows with unprecedented precision and repeatability. Applications include liquid-liquid extraction, mixing, reformatting and preparation of microtiter plates and more. It is also possible to pipet individual reagents through the pipeline using air gap separation. This feature greatly simplifies and speeds up the collection and mixing of multiple reagents in one well.
