Test Tube with Separate Blue Screw Cap, 16 x 120mm (15mL) Overview
The Globe Scientific Test Tube with Separate Blue Screw Cap (SKU 6155) is a 16 x 120mm polystyrene tube with a 15mL working format, supplied with a detachable blue screw cap for secure closure. Built for routine sample handling, this tube pairs clear PS construction with a leak-resistant threaded seal.
Each tube ships with its cap packaged separately, letting technicians fill, label, and seal at their own pace. Polystyrene gives excellent optical clarity for visual inspection of contents, while the molded threads accept the matching blue cap without cross-threading.
Standardized 16 x 120mm dimensions fit common tube racks, centrifuge adapters, and storage trays. Bulk case packaging supports high-throughput labs that consume disposable tubes in volume.

Laboratory Applications
Screw-cap polystyrene tubes serve sample collection, aliquoting, and short-term storage across clinical, research, and industrial labs. Threaded closures help reduce spillage during transport and inverting steps, making these tubes practical for buffer dispensing, dilution prep, and routine specimen holding.
Clear PS walls allow technicians to assess color, turbidity, and fill level at a glance. Standard rack-compatible dimensions let labs integrate these tubes into existing workflows for mixing, incubation, and benchtop organization without specialized adapters.
