⭕ DW Scientific Spiral Plater in perfect working order and clean condition. Purchased new in 2013. The DW Scientific Automatic Spiral Plater consists of microprocessor control for the deposition of liquid samples onto a rotating agar plate. Use of a spiral plater compared to conventional methods reduces set up time and consumable costs, eliminates serial dilutions, and reduces overall incubator space requirements. User-selected specifications allow a variety of dispensing options. Liquid is dispensed uniformly or with continuous decreasing volume across the plate. 30 Day Right to Return if not as described and available for shipping or local pickup.
