Bulk reagent dispenser
A bulk reagent dispenser (BRD) bụ ụdị ngwá ọrụ ụlọ nyocha dị na ahịa nke na-ekesa mmiri reagents n'ụzọ na-akpaghị aka n'ime microplates, multiwell plates, ma ọ bụ microplate-dị ka tankị, ma nwee ikike ịnyefe mmiri site na "bulk" (ya bụ >1L) isi iyi tankị, mana ka na-enye usoro ma ọ dị obere mmiri, ya bụ 10-500 μL. A na-ejikarị ha eme ihe na nchọpụta ọgwụ ma ọ bụ ụlọ nyocha ọgwụ. A na-ekewa ha site na ngwá ọrụ na-arụ ọrụ n'onwe ya ma ọ bụ nke aka (nke aka na-arụ) dị ka pipettes, yana ngwá ọrụ ụlọ nyocha na-arụkọ ọrụ n'ụzọ na-akpaghị aka nke na-ewepụ obere ebe nchekwa (~ 10-500 μL) dị ka ndị na-ahụ maka mmiri ma ọ bụ ndị na-arụ maka mmiri.

- 2-axis mmegharị site na iji X-Z gantry. Ọ bụrụ na ị na-eji BRD 2-axis, ọ nwere ike ijupụta microplates ma ọ bụ multiwell plates na oghere nke hà ma ọ bụ karịa oghere nke ntụziaka nkesa. Dịka ọmụmaatụ, a na-ezube BRD nwere ntụziaka 8-channel iji mejupụta efere 96 nke olulu, mana ọ nwekwara ike jupụta efere 24 nke olulu ọtụtụ, ma ọ bụ efere "otu olulu" (ya bụ, ọdọ mmiri).
- 3-axis movement site na iji X-Y-Z gantry. Ọ bụrụ na ejiri BRD 3-axis, ọ nwere ike jupụta microplates ma ọ bụ multiwell plates na oghere nke hà nhata, karịa, ma ọ bụ na-erughị oghere nke ntụziaka nkesa.
