Accurate, repetitive aliquoting in microplate wells is simple by slanting plates to an optimal angle by placing the plate on the adjustable mounting stand. Adding aliquots is simple with the microplate slanted at an angle that is optimal to the user's working habit and convenience. The slanted plate permits the user to track which wells have received aliquots by visibly contrasting the menisci between adjoining wells. Effortlessly view additions at any angle. Reduces operator error during pipetting
