Make precise additions of liquid components to microplate wells by adjusting plates to the most convenient angle. Additions required in in-vitro biological assays are easier when the microplate can be tilted and viewed at an angle. The angular presentation of the plate allows you to judge which wells have received liquid addition by comparing the menisci between neighboring wells. Adjustable angle settings can greatly reduce errors in non-manifold additions of assay components of expensive, hazardous or radioactive materials to a multiwell microplate. The clear acrylic platform beneath the microplate provides the best condition for observing the meniscus of a liquid within the well. An epoxy coated steel base provides stability, and the hand adjustable clamping screws maintain the desired angle. The stand holds all sizes of microplates up to 96 well size. Dimensions are 114 x 165 x 57mm high (4 5/8" x 6 1/2" x 2 1/4").
