A flow cytometer comprising: a collection sled including: a first sample collector located in a first position and having a first slanted surface and apertures that accept standard size sample collection tubes to collect samples from a first deflected droplet stream in the flow cytometer; a second sample collector located in a second position and having a second slanted surface and apertures that accept standard size sample collection tubes to collect samples from a second deflected droplet stream in the flow cytometer, wherein the second sample collector is spaced apart from the first sample collector to form an elongate opening located between the first slanted surface and the second slanted surface when viewed along the vertical axis, wherein the elongate opening is aligned with the single axis that the collection sled is configured to move along and configured to also be aligned with a waste droplet stream of the flow cytometer so that the waste droplet stream passes through the elongate opening into a cavity between the first sample collector and the second sample collector during movement of the collection sled along the single axis; a support structure that secures the first sample collector and the second sample collector; and a guide that is connected to the support structure that is configured to guide the support structure and the collection sled so as to be movable along a single axis that is at an angle that is substantially normal to the waste droplet stream; and a waste stream catcher positioned below the first sample collector and the second sample collector, wherein the cavity expands in a downward direction from the elongate opening towards the waste stream catcher to prevent backsplash of waste fluid from waste droplets in the waste droplet stream. a collection sled including: a first sample collector located in a first position and having a first slanted surface and apertures that accept standard size sample collection tubes to collect samples from a first deflected droplet stream in the flow cytometer; a second sample collector located in a second position and having a second slanted surface and apertures that accept standard size sample collection tubes to collect samples from a second deflected droplet stream in the flow cytometer, wherein the second sample collector is spaced apart from the first sample collector to form an elongate opening located between the first slanted surface and the second slanted surface when viewed along the vertical axis, wherein the elongate opening is aligned with the single axis that the collection sled is configured to move along and configured to also be aligned with a waste droplet stream of the flow cytometer so that the waste droplet stream passes through the elongate opening into a cavity between the first sample collector and the second sample collector during movement of the collection sled along the single axis; a support structure that secures the first sample collector and the second sample collector; and a first sample collector located in a first position and having a first slanted surface and apertures that accept standard size sample collection tubes to collect samples from a first deflected droplet stream in the flow cytometer; a second sample collector located in a second position and having a second slanted surface and apertures that accept standard size sample collection tubes to collect samples from a second deflected droplet stream in the flow cytometer, wherein the second sample collector is spaced apart from the first sample collector to form an elongate opening located between the first slanted surface and the second slanted surface when viewed along the vertical axis, wherein the elongate opening is aligned with the single axis that the collection sled is configured to move along and configured to also be aligned with a waste droplet stream of the flow cytometer so that the waste droplet stream passes through the elongate opening into a cavity between the first sample collector and the second sample collector during movement of the collection sled along the single axis; a support structure that secures the first sample collector and the second sample collector; and a guide that is connected to the support structure that is configured to guide the support structure and the collection sled so as to be movable along a single axis that is at an angle that is substantially normal to the waste droplet stream; and a waste stream catcher positioned below the first sample collector and the second sample collector, wherein the cavity expands in a downward direction from the elongate opening towards the waste stream catcher to prevent backsplash of waste fluid from waste droplets in the waste droplet stream.
