How spore syringes are made: the sterile protocol behind every MycoWorld LOT
A spore syringe looks simple: water and spores in a tube. What makes it a research specimen rather than a tube of unknown water is the process around it. This is that process, step by step, as the library runs it.
01The print
Everything starts with a spore print from a documented line: a deposit taken from a single cap onto sterile foil, sealed, and logged with the strain, the source and the date. The print is the genetic record. It is examined under the microscope before it is used, so that a contaminated or thin print never becomes a batch.
02The hood
Syringes are filled inside a laminar flow hood: a cabinet that pushes filtered air across the work surface so nothing airborne can settle on the open print, the water or the syringe tip. Everything that enters the hood is wiped with alcohol. The person filling works with gloves and does not lean over the airflow. This is the step that home-filled syringes skip, and it is the difference between a clean slide and a bacterial one.
None of it shows on the outside of the syringe. All of it shows on the slide.
03The water
Water is sterilised under pressure and cooled before use. Nothing is added to it. Nutrient in a syringe would feed any contaminant that got in and is the mark of a product made for something other than microscopy.
04Filling and capping
- A measured portion of the print is suspended in sterile water in a sterile vessel inside the hood.
- The suspension is agitated so the spores disperse evenly.
- Each 10 ml luer-lock syringe is drawn from the suspension and capped immediately.
- The syringe is labelled with the strain name and the LOT.
Batches are small and prepared to order, so no syringe waits long between filling and dispatch.
05The LOT record
Every batch has a reference that links the syringes to the print, the date, the strain and the collection it came from. It is on the label and on your order. If a batch ever shows a problem, the LOT is how it is traced and how every affected customer is contacted. It is also how your own notebook stays honest: a slide result without a LOT is a result you cannot repeat.
06Refrigeration and dispatch
Filled syringes go straight into refrigeration and stay there until they are packed, sleeved and capped, into an unbranded padded mailer for tracked UK dispatch. Once with you, the fridge takes over; the storage guide covers the rest.
07What you are paying for
A hood, sterile water, a logged print and a record. None of it shows on the outside of the syringe. All of it shows on the slide.

Questions people ask
What is in a MycoWorld spore syringe?
Sterile water and spores from a logged print of the named strain. Nothing else.
What does the LOT number on my syringe mean?
The batch reference linking your syringe to its print, date, strain and collection. Quote it for any query or replacement.
Why does sterile preparation matter for microscopy?
Because bacteria on the slide obscure and outnumber the spores. A syringe filled in a hood shows spores; one filled on a bench shows contamination.
