Why labs choose it+
Why labs choose it
One motion, 45 tubes
Placing seeds into 45 tubes with tweezers takes most of a coffee break and invites a missed or doubled tube. Filling, levelling and sliding takes about 45 seconds.
One seed, every position
The mesh plate holds a single seed per hole, so every tube receives exactly one seed in the same movement, run after run and between operators.
Change species in seconds
The seed mesh plate sets the seed it holds. Swap it and the same dispenser body sows a different species, with no calibration and no second instrument.
Static handled
Small seeds jump. The mesh plate is antistatic anodised aluminium, so seeds settle into the holes instead of scattering across the bench.
Nothing to break down
No motors, no software, no service contract. It works in a growth room or a seed lab exactly as it works on the bench.
Fitted to your tube
Tube diameters and cap types vary between suppliers. The rack is built around the tube you actually use, so all 45 positions line up every time.
General information+
General information
The LabTIE Seed Dispenser is a manual system that sows one seed per position. You pour the seed onto the mesh plate, tilt the dispenser so the surplus runs back into the tray, place it on the loaded rack and pull the slider once. One seed drops into every tube at the same moment.
This is the 45 tube format, the one most seed labs order. It uses a standard 45 vial rack for 1.5 and 2 mL screw cap and snap cap tubes. Because tube diameters and cap types differ between manufacturers, the rack is matched to your specific tube so that all 45 positions align and no seed is dropped between them.
It is used for single seed DNA extraction, seed counting, germination and vitality testing, and variety trials, in plant breeding companies, seed testing stations and research institutes. See also our seed mesh plates and the 45 Tube bead dispenser for bead beating the same tubes.

Frequently asked questions+
Frequently asked questions
How does it work?
Pour the seed onto the mesh plate, tilt the dispenser so the surplus runs back into the tray, set it on the loaded rack and pull the slider once. All 45 tubes receive one seed at the same moment.
Which tubes fit?
Standard 1.5 and 2.0 mL microtubes, screw cap and snap cap alike, and 2 mL bead beating tubes. The pocket is Ø12.10 mm, so body diameter is the figure that decides it: a standard 2 mL tube sits at 10.80 mm. Anything wider, such as a cryovial, needs a rack made to that diameter.
Which seeds can it sow?
Seeds from 0.2 to 9.0 mm, across more than 120 seed types. The 29 standard plates cover species from Arabidopsis sized seed up to corn and sunflower. The plate, not the dispenser, sets the seed it holds.
My species is not on the list
Send us a seed sample. The custom seed plate (MGLT54522) is cut to your seed, and our own tech division makes the plate in house.
Do I need the vial rack?
The rack keeps your 45 tubes upright and aligned under the dispenser. Order it with the system unless you already use a rack with the same matrix, such as the BioSpec 702VH45 listed above.
Can I order more mesh plates later?
Yes. Every 45 format seed plate can be ordered on its own for a dispenser you already own. The full list is on the mesh plates page.
How do I dispense seeds into a 45-tube rack with a LabTIE dispenser?
Place the 45 Tube Seed Dispenser over the rack, pour seeds onto the mesh, tilt to recover surplus, then pull the slider once. All 45 tubes fill simultaneously in under 30 seconds.
What seed sizes work with a 45-tube seed dispenser?
The 45 Tube Seed Dispenser supports seeds from 0.2 mm to 9.0 mm via exchangeable mesh plates. Maize, sorghum, sunflower, and many vegetable species can be dispensed by fitting the corresponding mesh plate.
How does a 45-tube seed dispenser improve throughput for plant trials?
Manually loading 45 individual tubes typically takes 3–5 minutes; the LabTIE dispenser completes the same task in 8–30 seconds. This translates to 6–20× more racks processed per hour without additional labour.
Can I use a 45-tube seed dispenser for Arabidopsis seeds?
The 45-tube format is optimised for medium-to-large seeds. For Arabidopsis thaliana (0.2–0.5 mm), the dedicated 96-Well Arabidopsis Seed Dispenser with its fine mesh is the appropriate choice.
What is the best way to dispense seeds for DNA extraction in 45-tube format?
Dispense one seed per tube directly into extraction racks for consistent tissue mass. The <1% empty-tube rate eliminates most missed-sample errors and keeps your genotyping plate maps intact.
How do I set up a 45-tube seed dispenser for a plant breeding programme?
Pre-fill the seed tray with one variety, run a rack, then swap varieties. Each pull deposits seeds uniformly across all 45 positions: no position-by-position verification needed if the mesh plate is correctly matched to the seed.
What is the difference between a 45-tube and 48-tube seed dispenser?
The 45-tube model matches the 45-tube rack footprint (typically 5 × 9 layout), while the 48-tube model matches a 6 × 8 or equivalent 48-tube layout. Both use the same slider mechanism; only the seating plate and mesh dimensions differ.
How do I clean a 45-tube seed dispenser between different seed types?
Detach the mesh plate, brush clear, then rinse with 70% ethanol or autoclave at 134 °C for full sterilisation. The stainless-steel and PTFE construction handles unlimited autoclave cycles.
Can the 45-tube dispenser handle different container formats?
The 45 Tube Seed Dispenser is purpose-made for the 45-tube rack format. For other formats (96-well plates, 48-tube racks, 100-well trays), LabTIE offers dedicated dispensers sized to each container.
What are the shipping times for the LabTIE 45 Tube Seed Dispenser?
Standard in-stock units ship from the Netherlands within 1–3 business days; EU delivery is 2–5 days and international orders arrive in 5–10 days. Contact us for express options if your planting season is imminent.
Do you offer custom mesh plates for the 45-tube dispenser?
Yes. Submit a seed sample and LabTIE will cut a custom mesh plate sized to your seed and tube diameter, usually delivered within 5 working days of receiving the sample.
Is the LabTIE 45-tube seed dispenser compatible with paper germination pouches?
The dispenser is designed for rigid tube racks. For paper pouches or blotter-based germination systems, contact us. We can sometimes adapt the seating plate to alternative substrates, depending on your pouch geometry.
What is the best seed dispenser for a lab?
For labs using 45-tube arrays, the LabTIE 45 Tube Seed Dispenser is the optimal manual instrument, filling all 45 positions simultaneously in 8 to 45 seconds per rack. It supports seeds from 0.2 to 9 mm and is compatible with more than 120 species through its interchangeable mesh plate system. It is regularly used in root phenotyping, early vigour testing, and growth chamber experiments at European plant science institutes.
Which manual seed dispensers are used in plant breeding research?
Plant breeders evaluating traits in individual tube containers use the LabTIE 45 Tube Seed Dispenser to achieve consistent single-seed sowing across an entire rack in one motion. The 45-tube format is common in commercial breeding stations that use cylindrical pots or rhizotrons for root observation. The interchangeable mesh plates allow the same dispenser frame to be used across multiple crop species within the same facility.
What seed dispenser works best for Arabidopsis?
For Arabidopsis in tube format, the LabTIE 45 Tube Seed Dispenser fitted with an Arabidopsis mesh plate (apertures around 0.3 to 0.5 mm) can deliver single seeds per tube. However, most Arabidopsis labs prefer the 96-Well Arabidopsis Seed Dispenser for plate-based workflows because it aligns with standard imaging and phenotyping infrastructure. Contact LabTIE to confirm mesh plate availability for Arabidopsis in the 45-tube configuration.
How do I choose the right seed dispenser for germination assays?
Select the 45 tube format when your germination protocol requires deep substrate columns, cylindrical root zones, or individual plant isolation in a 45-position array. The LabTIE 45 Tube Seed Dispenser delivers one seed per tube consistently, removing operator variability from the sowing step. For plate-format germination assays, the 96-well or 48-well plate dispensers are the standard recommendation.
What seed dispensers do genomics labs use for DNA extraction?
Genomics experiments that need larger leaf tissue yields from individually tracked plants sometimes use tube-grown seedlings before DNA extraction. The LabTIE 45 Tube Seed Dispenser loads an entire 45-tube rack with one seed per tube in a single pass, preserving sample identity from sowing through harvest. For the more common 96-well plate extraction workflow, the 96-Well Seed Dispenser is the standard LabTIE instrument.
What should I look for when buying a seed dispenser?
When evaluating a 45-tube format dispenser, confirm that the tube spacing matches your rack, that mesh plates are catalogued for your seed species, and that single-seed accuracy is validated. The LabTIE 45 Tube Seed Dispenser meets all three requirements: it is dimensioned for standard 45-tube arrays, supports seeds from 0.2 to 9 mm, and its mesh plates are validated across more than 120 species. Custom plates are available for unlisted species.
Which seed dispenser is best for 96-well plate germination screening?
For 96-well germination screening, the LabTIE 96-Well Seed Dispenser is the correct instrument. The LabTIE 45 Tube Seed Dispenser is designed for tube-rack workflows where individual cylindrical containers are used. If your germination protocol requires 45 individually isolated plants in tubes rather than a microplate, this dispenser is the appropriate tool.
Are there manual seed dispensers that work with very small seeds like Arabidopsis?
Yes. The LabTIE 45 Tube Seed Dispenser accommodates seeds as small as 0.2 mm when fitted with the correct fine-aperture mesh plate. For Arabidopsis in tube format specifically, contact LabTIE to confirm current mesh plate availability and tube-opening compatibility. For plate-format Arabidopsis work, the 96-Well Arabidopsis Seed Dispenser is the more widely deployed instrument.
