Injector septa help New Zealand laboratories seal containers, support tubing access and protect samples during transfer or storage workflows. Source silicone seal septa, vulcanized PTFE insert seals and GL screw-thread sealing components through our Laboratory range, with supply support from Labfriend.
Injector Septa
Injector Septa for New Zealand Laboratory Sealing Workflows
Injector septa support secure closure, tubing access and controlled sample handling in laboratory glassware and cap assemblies. This category includes silicone seals with vulcanized PTFE inserts, silicone seal septa, GL screw-thread options and tube diameter formats for routine or specialist laboratory containment tasks.
- Product Scope: Silicone seal septa, PTFE insert seals and GL thread sealing components for laboratory containers and caps.
- Supply Support: Available through Labfriend and the wider John Morris Group laboratory supply network.
- Thread Sizes: Visible products include GL 14, GL 18, GL 25 and GL 32 options for compatible screw-thread cap systems.
- Tube Ranges: Visible seal options support tube diameters including 5.5-6.5 mm, 7.5-9 mm, 9-11 mm, 15-17 mm and 17-19 mm.
- Applications: Bottle sealing, tubing connection, sample containment, reagent transfer, injection access and closed vessel workflows.
Choosing Injector Septa by GL Thread and Tube Diameter
Selecting the correct injector septa depends on the cap thread, tubing diameter, chemical exposure and cleaning process. A correct fit helps maintain a secure seal, reduce leakage and support safe laboratory handling when tubing or access points are used with glass bottles or screw caps.
- Thread Compatibility: Match GL 14, GL 18, GL 25 or GL 32 seal options to the compatible cap or bottle thread.
- Tubing Fit: Choose the seal according to the stated tube diameter range to support reliable positioning and sealing.
- Chemical Resistance: Select PTFE insert seals where the contact surface may be exposed to solvents or reagents.
- Sterilisation Needs: Review autoclavable options where seals will be used in sterilised or heat-cleaned workflows.
- Workflow Use: Confirm whether the seal will be used for tubing pass-through, sampling, injection access or general container sealing.
Supporting Categories for Caps, Glassware and Connections
Injector septa are often ordered with compatible caps, bottles, tubing and adapters used in the same workflow. New Zealand buyers may also need Caps or Tops, Laboratory Adapters or Connectors or Fittings or Laboratory Vials.
- Laboratory Supplies and Fixtures: Supports seals, caps, fittings and bench consumables used across routine laboratory workflows.
- Laboratory and Scientific Equipment: Relevant for laboratories connecting vessels, tubing, instruments and sample handling equipment.
- Test and Measurement: Supports workflows where sample access, sealed transfer and measurement integrity are important.

Frequently Asked Questions
What products are included in this injector septa category?
The visible range includes silicone seals with vulcanized PTFE inserts, silicone seal septa and GL thread seal options for laboratory bottles and caps.
Are PTFE insert silicone seals suitable for chemical workflows?
PTFE insert silicone seals are useful where improved chemical resistance is required at the contact surface. Buyers should still confirm compatibility with the specific solvent, reagent, temperature and cleaning method used onsite.
Can the New Zealand team help confirm septa compatibility?
Yes. The New Zealand team can help review GL thread size, tubing diameter, chemical exposure, sterilisation requirements and the intended laboratory setup before purchase. Contact 0800 651 700 for support.
