APPARATUS FOR THE APPLICATION OF SAMPLES ON A SUBSTRATE
摘要
<p>Novel apparatuses and methods for depositing or placing substances on substrates or plates are described. The invention relates to automated and semiautomated apparatuses and methods for controlled volume and precise placement of substances on substrates. Combinations of applicator tips, applicator tip assemblies, applicator reservoirs, applicator holders and movable racks precisely and accurately place samples and testing chemicals on substrates. Applicator tips particularly useful for dunk transfer and deposit processes and for carrying substances are disclosed. Apparatuses for precisely moving applicator holders, applicator reservoirs and tips are disclosed. The methods and apparatuses also have features for pre-loading substances on applicators and applicator reservoirs and precisely delivering the preloaded substances to substrates.</p>
