Falcon® 352008 | 5mL Round Bottom Polystyrene Test Tube, Without Cap, Non-Sterile — 1000/Case

Product Description

The Falcon® 352008 is a 5mL round-bottom polystyrene test tube without cap — non-sterile, supplied in bulk quantities of 1,000 tubes per case, and the most economical format in the Falcon round-bottom polystyrene tube family. Widely used and referenced in laboratory protocols. Specialized tube for flow cytometry applications. Provide reliable containment of laboratory fluid samples. Widely referenced in published procedures and protocols. Polystyrene tubes are best suited for procedures requiring high optical clarity. Rated to 1,400 RCF. 12 × 75mm. 1,000 tubes per case.

Without Cap — Maximum Flexibility for Sample Addition and Flow Cytometer Loading The cap-free design of the 352008 is a deliberate and important feature for the primary applications of this tube format. In flow cytometry workflows, tubes are frequently loaded directly into the flow cytometer sample injection port without caps — requiring cap removal before every acquisition run. In high-throughput antibody staining workflows where tubes are processed on ice in racks, caps are typically removed during pipetting and not replaced between steps. The cap-free 352008 eliminates the cap removal step entirely — streamlining the workflow and reducing the per-tube handling time in high-volume flow cytometry labs.

Non-Sterile — The Economic Choice for Non-Aseptic Applications The 352008 is non-sterile — the appropriate choice for all flow cytometry, immunology, and hematology applications where tube sterility is not a requirement. For antibody staining, surface marker analysis, intracellular staining, cell viability assays, and flow cytometer sample loading where fixed or non-living samples are handled, the non-sterile 352008 provides identical performance to the sterile 352058 at a significantly lower per-tube cost. Dual position snap-cap prevents sample loss with ease of handling; provides a secure, positive seal (except for items 352008, 352017, and 352052 which do not have caps). 

352008 vs. 352058 — Choosing the Right 5mL Round-Bottom Tube: The 352008 and 352058 use identical polystyrene construction and 1,400 RCF rating — the key differences are sterility, cap, and pack size:

Polystyrene Construction — Exceptional Optical Clarity for Flow Cytometry Polystyrene tubes are best suited for procedures requiring high optical clarity. The clear polystyrene construction of the 352008 provides exceptional optical transparency — critical for visual inspection of cell pellets, antibody staining reactions, and sample color. For flow cytometry applications where tubes are loaded directly into the cytometer sample injection needle, the polystyrene material is fully compatible with all standard aqueous buffers, staining reagents, fixatives (paraformaldehyde, formaldehyde), and cell suspension media used in standard flow cytometry protocols.

1,400 RCF Rating — Reliable for Standard Wash Steps The 352008 is rated to 1,400 RCF — covering all standard centrifugation steps in flow cytometry sample preparation including antibody staining wash spins, cell pelleting, red blood cell lysis and wash, and density gradient centrifugation for PBMC isolation within the tube's rated speed range.

Flow Cytometry — The Reference Standard Non-Sterile Tube Specialized tube for flow cytometry applications. The Falcon 352008 5mL round-bottom non-sterile tube without cap is the default tube for flow cytometry in thousands of published protocols and institutional SOPs. When a flow cytometry protocol specifies "Falcon 5mL tubes" without specifying sterile or capped format, the 352008 is frequently the intended product — particularly in core facility environments where large quantities of tubes are consumed daily and the lower cost of the non-sterile bulk format is operationally significant.

1,000/Case — Bulk Economical Packaging for High-Volume Labs The 352008 is supplied 1,000 tubes per case — double the 500-tube case quantity of the sterile 352058 — providing the bulk supply that high-throughput flow cytometry labs, immunology cores, and hematology laboratories require. For labs running 50–200 samples per day in flow cytometry, the 1,000-tube case format minimizes order frequency, reduces per-tube cost, and simplifies inventory management.

Widely Used and Referenced in Published Protocols Widely used and referenced in laboratory protocols. Widely referenced in published procedures and protocols. The Falcon 352008 is cited by catalog number in thousands of published flow cytometry, immunology, and hematology protocols — making it the default choice for researchers following established procedures and for core facilities standardizing on published SOPs.
