In specialist haematology and apheresis services, vascular access can be very different from routine intravenous access.
Patients undergoing procedures such as automated red cell exchange or therapeutic plasma exchange may require reliable, high-flow access to an implanted vascular port. In these situations, the needle is not simply a means of gaining access. Its gauge, length, design and flow characteristics can all be important considerations.
For healthcare professionals looking for a 16G × 1 inch straight high-flow non-coring needle, product selection therefore needs to be much more specific than searching for a conventional Huber or port-access needle.
What is a 16G high-flow non-coring needle?
A 16G high-flow non-coring needle is a specialist needle designed to provide access to an implanted vascular access port while supporting applications where higher flow rates may be required.
The 16G × 1 inch configuration is particularly relevant when a larger-bore, straight-access needle is required.
Unlike a conventional needle, a non-coring needle is designed to access the self-sealing septum of an implanted port without unnecessarily cutting or removing a core of septum material.
This distinction becomes particularly important when a port is accessed repeatedly over time.
Why are high-flow needles used in apheresis?
Apheresis involves removing blood from a patient, processing or separating specific blood components, and returning the required components to the patient.
The technique is used in a range of specialist clinical applications, including red blood cell exchange and therapeutic plasma exchange.
NHS patient information confirms that implanted Vortex ports can be used for automated red cell exchange and therapeutic plasma exchange. During an exchange procedure, separate access points may be used for withdrawing and returning blood.
For these applications, vascular access needs to accommodate the requirements of the treatment system and the clinical protocol.
This is where a high-flow, large-gauge non-coring needle can become particularly relevant.
Why choose a non-coring needle for implanted port access?
Implanted ports contain a self-sealing septum that is designed to be punctured when the port is accessed.
Repeated access means that needle design matters.
A non-coring needle is designed specifically for access through the port septum, helping to minimise the removal of septum material compared with a conventional cutting needle.
For specialist departments where ports may be accessed repeatedly, the ability to maintain reliable port integrity is an important consideration.
However, the correct needle should always be selected according to the specific implanted port, manufacturer’s instructions, clinical procedure and local NHS protocol.
16G × 1 inch: understanding the specification

Key features to look for
When sourcing 16G high-flow non-coring needles, healthcare procurement teams and clinical users should consider more than gauge and length.
A 16G configuration provides a larger internal pathway than many conventional port-access needles.
This makes it particularly relevant to specialist high-flow applications where the required flow characteristics differ from routine medication administration.
The 1-inch configuration provides approximately 25.4 mm of needle length.
Needle length should always be checked against the relevant port and clinical requirements rather than assumed to be universally suitable.
The non-coring design is one of the most important characteristics.
The needle is intended to pass through the port’s self-sealing septum while reducing the potential for coring associated with conventional needle designs.
Some clinical applications require a straight needle rather than a winged or angled Huber configuration.
For specialist high-flow port access, the precise needle configuration should be matched to the port system and the established clinical technique.
Not all Huber needles are high-flow needles.
A standard port-access needle may be suitable for routine infusion or blood sampling but may not be an appropriate substitute where a clinical service specifically requires a high-flow needle.
For clinical use, product sterility, packaging, traceability and single-use status should be confirmed as part of the procurement process.
Benefits of selecting the correct high-flow non-coring needle
Supports specialist high-flow applications
A large-gauge high-flow needle can be appropriate for clinical applications requiring higher flow characteristics, including specialist apheresis procedures where compatible port systems are used.
Designed for implanted port access
The non-coring design is specifically intended for accessing compatible implanted port septa.
Helps support repeated port access
For patients requiring repeated treatment through an implanted port, selecting an appropriate non-coring needle is an important part of maintaining the port-access system.
Specialist rather than generic port access
A key benefit of selecting a purpose-designed high-flow needle is that it avoids treating all Huber or non-coring needles as interchangeable.
A 16G high-flow needle is not simply a larger version of a standard port-access needle. The application, port compatibility and clinical requirements need to be considered together.
Suitable for specialist procurement
For NHS procurement teams, having the exact gauge, length and configuration available makes it easier to identify the correct product and avoid unsuitable substitutions.
High-flow needle vs standard Huber needle
One of the most important distinctions for procurement teams is the difference between a standard Huber/non-coring needle and a specialist high-flow non-coring needle.

Important: A standard Huber needle should not be substituted for a high-flow needle solely because it has the same length or is also described as “non-coring”. The clinical team should confirm compatibility and suitability.
What is a Vortex port?
A Vortex port is an implanted vascular access system used in specialist care.
NHS information explains that a Vortex port is implanted under the skin and can be used for blood sampling, fluids and drug treatment. It can also provide access for procedures such as automated red cell exchange and therapeutic plasma exchange.
During an exchange procedure, access through the port allows blood to be withdrawn and returned through the appropriate channels.
This makes the combination of port + appropriate high-flow access needle + apheresis equipment an important consideration for specialist services.
Who may use 16G high-flow non-coring needles?
This is a particularly specialist product category and is most relevant to healthcare teams involved in high-flow vascular access.
Potential users include:
The precise application will depend on the patient’s implanted port, treatment pathway and local clinical guidance.
16G high-flow needles and red cell exchange
Automated red cell exchange is used in specialist haematology, including the management of selected patients with sickle cell disease.
The procedure requires reliable vascular access so that blood can be removed and replacement blood returned through the treatment system.
For patients with suitable implanted ports, a high-flow non-coring needle may form part of the access arrangement.
The important consideration is that the needle must be appropriate for the port and procedure. It should not be selected purely on gauge and length.
16G high-flow needles and therapeutic plasma exchange
Therapeutic plasma exchange is another specialist apheresis procedure in which blood is processed to remove and replace plasma.
As with red cell exchange, the vascular access requirements are more demanding than those associated with routine intravenous therapy.
Where an implanted port is used, a suitable high-flow non-coring access needle may be required according to the port manufacturer’s instructions and the clinical team’s established procedure.
How should NHS teams specify a high-flow needle?
If you are requesting quotations or checking availability, providing the full specification can make the sourcing process much easier.
Instead of simply requesting:
“16G non-coring needles”
consider specifying:
16G × 1 inch (25.4 mm) straight high-flow non-coring/Huber needle for implanted port access, suitable for the intended specialist high-flow application.
The procurement team should also confirm:
Why exact product matching matters
Specialist apheresis consumables can have very specific requirements.
A product that appears similar in a catalogue may not be an appropriate substitute.
For example, two needles may both be described as 16G non-coring needles, but differences in design, flow characteristics, length, port compatibility and intended application can make them clinically different products.
For this reason, Niche Healthcare recommends that healthcare professionals provide the existing product reference, photograph or full specification wherever possible when requesting an alternative or quotation.
This allows the product to be checked against the clinical requirement rather than relying on a generic description.
Frequently Asked Questions
What is a 16G high-flow non-coring needle?
A 16G high-flow non-coring needle is a large-bore needle designed for accessing compatible implanted vascular ports in applications where higher flow characteristics are required. The non-coring design is intended to minimise coring of the port septum.
What is a 16G × 1 inch Huber needle used for?
A 16G × 1 inch Huber-style needle can be used for compatible implanted port access where a large-gauge, high-flow configuration is required. Applications may include specialist apheresis and blood exchange procedures, subject to the port manufacturer’s instructions and clinical protocol.
Are all Huber needles suitable for apheresis?
No. Huber or non-coring needles are available in many different configurations and are not automatically suitable for high-flow apheresis applications. The gauge, design, flow characteristics and compatibility with the implanted port must be considered.
Why is a non-coring needle used with an implanted port?
Implanted ports have a self-sealing septum designed to be punctured for access. A non-coring needle is designed to access this septum while minimising the removal of septum material.
What is the difference between a Huber needle and a high-flow needle?
“Huber” generally refers to a non-coring needle design used for accessing implanted ports. A high-flow needle is specifically configured for applications requiring higher flow characteristics. A high-flow needle can therefore be a specialist type of non-coring port-access needle.
What gauge are high-flow port-access needles?
There is no single universal gauge for all high-flow port access. Specialist products can include larger gauges such as 16G or 18G. The correct gauge should be determined by the specific port, procedure and manufacturer’s guidance.
Are 16G high-flow needles used in haematology?
They can be used in specialist haematology and apheresis settings where compatible implanted ports and treatment protocols require high-flow access. This can include applications such as automated red cell exchange and therapeutic plasma exchange.
Are 16G × 1 inch non-coring needles suitable for every port?
No. Port compatibility must always be confirmed. Needle gauge, length, design and intended flow characteristics should be matched to the implanted port and clinical procedure.
