Centrifuge Tube Family, 0.5–50 mL

Compare 0.5–50 mL polypropylene centrifuge tubes by capacity, closure, bottom style, sterility and packaging.

PRODUCT DETAILS

0.5–50 mL Centrifuge Tube Family for Laboratory Sample Processing

Puretest supplies clear polypropylene centrifuge tubes from micro-volume 0.5 mL formats through 50 mL conical and self-standing formats. This family page helps buyers compare capacity, closure, bottom geometry, sterility and packaging before requesting samples.

Product Highlights

0.5–50 mL selection: Microcentrifuge, intermediate-volume and standard conical formats.
Clear polypropylene construction: Supports visual sample and pellet inspection.
Multiple bottom geometries: Conical, round-bottom and self-standing/skirted supply options are available by SKU.
Snap-cap and screw-cap formats: Match the closure to the volume and workflow.
Graduations and writing areas: Support approximate volume checks and traceable labeling.
Sterile and non-sterile options: Select according to protocol and documentation needs.
Bagged and rack supply: Packaging can be matched to manual or production-scale use.
OEM support: Samples, drawings, labels, cartons and cleanliness documentation can be discussed.

Product Structure and Functional Design

Microcentrifuge tubes use an integral hinged cap and conical microtube body. Larger 10, 15 and 50 mL tubes use threaded necks and screw caps. Conical bottoms concentrate pellets; round bottoms support selected mixing and culture workflows; skirted 50 mL versions stand independently on a bench.

Technical Specifications

Family	Capacity	Closure	Bottom Options	Sterility
Microcentrifuge	0.5, 1.5, 2.0 mL	Hinged snap cap	Conical	Sterile / non-sterile
Intermediate	10 mL	Screw cap	Conical	Sterile bagged
Standard conical	15 mL	Screw cap	Conical; selected round-bottom options	Sterile bagged / rack options
Large conical	50 mL	Screw cap	Conical, round or self-standing/skirted	Sterile bagged / rack options

Application Guide

Capacity	Typical Workflow
0.5 mL	Low-volume aliquots, PCR-reagent preparation and small-sample centrifugation
1.5 / 2.0 mL	Routine molecular, protein, microbial and sample-preparation workflows
10 mL	Intermediate-volume clarification, reagent preparation and sample concentration
15 mL	Cell washing, routine sample processing and conical-tube centrifugation
50 mL	Larger-volume cell harvesting, buffer preparation, storage and decanting

Workflow and Equipment Compatibility

Capacity alone does not determine compatibility. Match the exact tube diameter, length, bottom, cap clearance, rotor bucket and adapter. Maximum RCF and temperature limits must be taken from the quoted SKU and validated under the intended fill and sample conditions.

Material, Cleanliness and Quality Documentation

The tube family uses clear polypropylene supply configurations with cleanliness claims tied to the selected SKU. Heavy-metal status, pyrogen/endotoxin status, cytotoxicity, DNase/RNase status, sterilization method, SAL, temperature range and batch documents must be confirmed on the quotation rather than inferred from the family description.

Ordering Information, Packaging and OEM Supply

Request the current catalog matrix for sterile/non-sterile status, bag or rack quantity, cap color, cleanliness documents and case configuration. Puretest can discuss private-label bags, distributor cartons and project-specific case marks.

Choose the Right Centrifuge Tube Capacity

Capacity / Page	Structure	Typical Selection
0.5 / 1.5 / 2.0 mL microcentrifuge tubes	Hinged snap cap; conical microtube	Small-volume sample preparation
10 mL conical centrifuge tube	Screw cap; conical bottom	Intermediate-volume processing
15 mL conical centrifuge tube	Screw cap; conical bottom	Routine cell and sample processing
50 mL conical / self-standing tube	Screw cap; conical or skirted option	Larger-volume centrifugation and storage
0.5–50 mL family selection guide	Family comparison	Capacity and bottom-style selection

Maximum RCF depends on the exact tube, rotor, adapter, fill volume and temperature. Request the current specification and validate samples before routine use.

Frequently Asked Questions

Question	Answer
Should different capacities be combined on one product page?	This page is a selection guide. Capacity-specific pages provide the technical and ordering details for routine purchasing.
What is the difference between conical and self-standing tubes?	A conical tube requires a rack, while a skirted or self-standing base allows the tube to stand independently.
Can every polypropylene tube be autoclaved or frozen?	No. Confirm the exact SKU, cap, time, temperature and sample conditions.
How do I select a maximum RCF?	Use the lowest limit among the tube, rotor, bucket and adapter after accounting for fill volume and temperature.
Are rack and bulk packs interchangeable?	The tube may be equivalent, but pack sterility, handling and case quantities differ. Confirm the quoted configuration.
Can you match an existing tube?	Send the current catalog number, dimensions, photos, rotor information and required certifications for comparison.
