Cary-Blair Gel Transport Swab

The Cary-Blair Gel transport swab is a complete microbiology collection-and-transport system consisting of a fitted specimen swab, a long narrow protective tube and a short column of clear semisolid medium at the rounded tube base. Low-nutrient, semisolid enteric transport medium intended for fecal or rectal-swab specimens when the receiving protocol specifies Cary-Blair. It is not a vacuum blood collection tube and must be matched to the specimen type, organism target and receiving-laboratory protocol.

Product Highlights

• Clear / pale Cary-Blair semisolid transport medium.
• Complete swab-and-tube system for closed post-collection transfer.
• Short gel column at the tube base helps keep the inserted swab tip in contact with the specified medium.
• Tube, swab, sterility, expiration dating and packaging are controlled by the selected SKU.

Structure and Materials

Typical Applications

• Fecal specimen transfer for bacterial enteric testing
• Rectal-swab collection when accepted by the receiving laboratory
• Enteric-pathogen transport programs using a validated Cary-Blair method

Use and Handling Overview

• Open the sterile pack without touching the collection tip.
• Collect only from the specimen site and by the technique defined in the validated protocol.
• Insert the swab into the tube so the collection tip reaches the gel column, then secure the closure.
• Label, store and transport the system within the time and temperature limits specified for the selected SKU and receiving method.

Important: The customer is responsible for validating the complete collection, transport and downstream test workflow.

Technical Specifications

Selection Guide

Cary-Blair is the enteric-focused option in this family. It should not be selected as a general substitute for Amies or Stuart media. Medium, swab material, specimen source and downstream method are not automatically interchangeable. Confirm the exact validated configuration before ordering.

Ordering Information

Frequently Asked Questions

Is this a blood collection tube?

No. It is a long narrow microbiology transport tube supplied around a specimen swab and a short gel column.

Is the transport medium interchangeable with other media?

No. Use Cary-Blair only when it is accepted by the validated collection and receiving-laboratory protocol.

What does the charcoal version change?

This clear version does not contain charcoal. If the method requires adsorption of inhibitory compounds, ask whether the matching charcoal formulation is specified.

Is the tube filled with liquid?

No. The illustration shows a short column of semisolid transport medium at the tube base.

Where should the swab tip sit after collection?

When the validated instructions require it, the inserted collection tip should reach the semisolid medium column before the closure is secured.

Which swab tip is included?

Tip and shaft material depend on the selected configuration and are confirmed before quotation.

Is the system sterile?

Sterile configurations may be available; the method, shelf life and documentation are SKU specific.

Can cap color be used as the only identifier?

No. Cap color may vary by configuration. Always verify the printed SKU and medium specification.

What should I send for a quotation?

Provide required medium, charcoal or clear version, specimen type, swab preference, sterility, pack quantity and order volume.
