1. A system comprising:
a liquid transfer device (100) comprising a housing (110) having a plurality of pipette tips (120) extending from a bottom surface of the housing (110), and a plunger assembly (130) disposed within the housing (110); and
a fluid reservoir (300) comprising a housing having an opening,
wherein a bottom periphery of the housing (110) of the liquid transfer device (100) comprises an asymmetrical cross-section (105) that is compatible with a cross-section of the opening of the housing of the fluid reservoir (300), such that when the liquid transfer device (100) is mated with the fluid reservoir (300), the bottom periphery of the housing (110) sealably engages with the opening of the housing of the fluid reservoir (300), and the plurality of pipette tips (120) is disposed within the fluid reservoir (300).
 
19. A system comprising:
a liquid transfer device (100) comprising:
a housing (110) having a first pipette tip (120) extending from a bottom surface of the housing (110) and a second pipette tip (120) extending from the bottom surface of the housing proximate the first pipette tip (120); and
a plunger assembly (130) disposed within the housing (110);
a fluid reservoir (300) comprising a housing having an opening; and
a reaction chamber (200) comprising a housing having an opening,
wherein a bottom periphery of the housing (110) of the liquid transfer device (100) comprises an asymmetrical cross-section (105) that is compatible with a cross-section (305) of the opening of the housing of the fluid reservoir (300) such that when the liquid transfer device (100) is mated with the fluid reservoir (300), the bottom periphery of the housing (110) sealably engages with the opening of the housing of the fluid reservoir (300);
wherein the asymmetrical cross-section (105) of the bottom periphery of the housing (110) of the liquid transfer device (100) is compatible with a cross-section (205) of the opening of the housing of the reaction chamber (200) and, when the liquid transfer device (100) is mated with the reaction chamber (200), the bottom periphery of the housing (110) lockably engages with the opening of the housing of the reaction chamber (200); and
wherein the opening of the housing of the reaction chamber (200) has an asymmetrical cross-section (205) that is compatible with the cross-section (305) of the opening of the housing of the fluid reservoir (300) and, when the reaction chamber (200) is mated with the fluid reservoir (300), the opening of the housing of the reaction chamber (200) lockably engages with the opening of the housing of the fluid reservoir (300).
