Polystyrene (PS) round-bottom test tubes in the 12 × 100 mm format for laboratory sample handling. Choose the uncapped tube or request a matched closure configuration, with packing confirmed for your order.
A plain open-mouth cylindrical body with smooth sidewalls and a rounded closed end. The mouth has no external screw thread.
Use an appropriately sized support rack to hold round-bottom tubes upright. The tube dimensions and opening geometry should be checked against the intended holder and handling method.

Dimensions are nominal selection references. Working volume and dimensional tolerances are not stated; request the applicable drawing and supplied-product specification when these are critical.
The second gallery image shows examples from the cap and stopper range, including winged and cylindrical designs. These accessory examples are not a universal fit claim. Request a matched closure for this exact tube material, diameter and mouth design before ordering.
| Configuration | Tube material and size | Closure | Reference packing |
|---|---|---|---|
| Uncapped tube | PS; 12 × 100 mm | Open mouth | 300/bag; 3,000/case |
| Optional matched closure | PS; 12 × 100 mm | Cap / stopper selection subject to exact fit confirmation | Confirm with quotation |
Packing is configuration-specific and subject to the confirmed quotation. Select one complete tube-and-closure configuration; accessory colors and quantities shown in the gallery are illustrative.
For general laboratory sample containment, preparation and handling where this tube format is specified. Select the material, closure and cleanliness requirements to match the intended laboratory procedure. No universal chemical, assay, instrument or transport compatibility is claimed.
12 × 100 mm identifies nominal outside diameter × tube length. It does not specify internal volume, guaranteed dimensional tolerances or the overall height after adding a cap. Confirm a drawing or sample if the tube must fit a particular holder.
Matched caps or stoppers can be requested. The accessory gallery illustrates available closure styles; the actual fit must be confirmed for the selected tube. Cap color or nominal tube diameter alone is not enough to establish compatibility.
Sterility is not established by the product image or the presence of a cap. Specify your requirement and confirm the labeling, packing and documentation for the supplied configuration before ordering.
No automatic substitution is intended. This page covers Polystyrene (PS). Material, dimensions, mouth design and the intended laboratory method should all be considered when selecting a tube.
No centrifugation speed, RCF, autoclave or temperature rating is specified for this page. Ask for the validated operating limits of the exact supplied tube and closure before using them under those conditions.
No. Gallery images show product appearance and closure options. The number of pictured tubes or cap colors does not define sales-pack contents. Refer to the selected packing configuration in the quotation.
Check the 12 mm nominal outside diameter, 100 mm tube length, round bottom and mouth geometry against the holder requirements. Request a sample when fit is critical; no universal rack or analyzer compatibility is implied.
Provide PS, 12 × 100 mm, capped or uncapped supply, required cap design or color, packing, sterility requirements, quantity and delivery destination. Include a current sample photo or drawing if matching an existing product.
Send your required material, size, closure, packing and quantity. Contact Puretest for samples and a matched quotation.
Gallery images are illustrative product renderings. Final appearance and specification follow the confirmed supplied configuration.
