Product Description
Details

The Luer Lock combi-stopper is the small sterile cap that turns a half-used spore syringe into a syringe you can safely use next session. In DIY mycology, it's the difference between losing a precious spore suspension to contamination and getting a second or third inoculation out of one syringe.


What a combi-stopper is

A Luer Lock combi-stopper is an individually sterile-packed cap that screws onto the syringe hub in place of a needle. The combi (combination) design fits both Luer Lock and slip-tip connections — one cap, any standard syringe.


Why mycologists need one

Most hobby mycologists don't use a full 10 ml of spore solution in a single session. The remaining syringe is valuable — but only if it stays sterile until the next jar, bag or cake. Capping with a fresh combi-stopper is the only reliable way to do that.

Frequently asked questions

Frequently asked questions
QuestionAnswer
Why do I need a combi-stopper if I already have a needle?Storing a syringe with a used needle attached invites contamination. A fresh, sterile combi-stopper seals the hub for safe between-session storage.
Can I reuse a combi-stopper?No — single-use only. Open a fresh one each time you cap a syringe.
Is it Luer Lock specific?It fits both Luer Lock and Luer Slip — the universal design works on any standard syringe hub.
Sterile vs. sterilized?Each combi-stopper comes individually sterile-packed (EO-sterilized) and is CE-marked single-use.


Responsible sterile practice

Single-use, individually sterile-packed disposables intended for DIY mycology hobby and research use. Always pair with disciplined sterile technique — flame-sterilize all hub junctions before reuse and discard the combi-stopper after one storage cycle.
