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.

Ndị na-ekesa nnukwu reagent nwekwara ọwa na ndụmọdụ maka ikesa mmiri mmiri. Dabere na nhazi kọlụm 8 ma ọ bụ kọlụm 12 nke microplates ọkọlọtọ, ndị na-ekesa nnukwu reagent ọgbara ọhụrụ nwere ugbu a:
- Ntuziaka nkesa 8-channel (ụzọ dị larịị iji mejupụta microplate) ma ọ bụ
- Ntuziaka nkesa nke ụzọ iri na abụọ (ụzọ kwụ ọtọ iji mejupụta microplate)

[dezie | dezie ebe o si]E wezụga ụdị na ọnụ ọtụtụ nke pọmpụ onwe ha, ọwa, na ndụmọdụ, BRDs nwekwara ike iji manifold kesaa mmiri:
- na manifold (1-inlet kwa ọtụtụ ntụziaka dispense, nke a na-ahụkarị na mgbapụta ntanye BRDs), ma ọ bụ
- enweghị manifold (otu-inlet kwa ọwa ọ bụla, na otu-channel kwa isi ọ bụla, nke a na-ahụkarị na BRDs peristaltic pump).
Ọ bụrụ na ma ọ bụ mmiri na-abanye ma ọ bụ na-ewepụta ihe na-eme ka ọ bụrụ akụkụ ma ọ bụ kpamkpam, arụmọrụ nke BRD ga-emebi n'ụzọ dị iche iche na nke nwere ike ịbụ ụzọ aghụghọ dabere ma ọ bụrụ na ejirila manifold ma ọ bụ ghara.
Akụkụ ndị na-agagharị agagharị
[dezie | dezie ebe o si]Ndị na-ekesa reagent buru ibu na-achọ ịkwaga ndụmọdụ ndị a na-enyefe gafere n'olulu mmiri ndị a na-achọsi ike, dị ka ọnụ ọgụgụ dị nta nke nfuli na ndụmọdụ nwere ike imeju ọnụ ọgụgụ buru ibu nke olulu mmiri microplate. Ma n'agbanyeghị, e nwere ụdị ole na ole:
- 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. Dịka ọmụmaatụ, a BRD nwere ntụziaka 8-channel na-ezube iji mejupụta efere 96 nke olulu, mana ọ nwere ike mejupụta efera 384 site na ịkwaga ntụziaka (ma ọ bụ efere) na Y axis.
Ọ bụ uru na-ekwu, na n'ihi na ihe mere nke ohere & presumably n'ibu imewe mgbochi, ogo nke nnwere onwe nke ije maka a BRD na-a gbasaa gafee ma Atụmatụ na microplate. I.e. A na-ebugharị microplate na nha X, ebe ndụmọdụ na-agagharị na akụkụ Z (na Y).
