Why labs choose it+
Why labs choose it
One motion, 48 tubes
Placing seeds into 48 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.
Each tube in its own pocket
The converter registers every tube in a Ø12.00 mm pocket instead of clamping the rack, so cap style and tube height do not affect the fit. Screwcap, snapcap and GC vials all seat the same way.
Static handled
Small seeds jump. The mesh plate is antistatic anodised aluminium, so seeds settle into the holes instead of scattering across the bench.
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.
Fitted to your tube
Tube diameters and cap types vary between suppliers. The rack is built around the tube you actually use, so all 48 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 48 tube format, used where a run is counted in tubes rather than wells, typically for single seed DNA extraction. The Dispenser (converter) registers each tube in its own Ø12.00 mm pocket on a 14.00 mm grid and seats on the rack rim, so the tube body diameter is the only figure that decides the fit. Because tube diameters and cap types differ between manufacturers, the rack is matched to your specific tube so that all 48 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, the 45 Tube seed dispenser and the 48 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 48 tubes receive one seed at the same moment.
Which tubes fit?
Standard 1.5 and 2.0 mL microtubes, screwcap and snapcap alike, and 2 mL GC autosampler vials. The pocket is Ø12.00 mm, so body diameter is the figure that decides it: a standard microtube sits at 10.80 mm. Anything wider, such as a cryovial or a 5 mL tube, needs a converter built to that diameter.
Does the cap style matter?
No. Each tube is registered by its own pocket rather than by brackets closing around the rack, so cap style and tube height do not affect the fit. Tube height is set at build time when the rack is made to your tube.
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 (MGLT54824) is cut to your seed, and our own tech division makes the plate in house.
Can I order more mesh plates later?
Yes. Every 48 tube 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 48-tube racks with a LabTIE dispenser?
Seat the 48 Tube Seed Dispenser over your rack, pour seeds onto the mesh, tilt to return surplus, then pull the slider. All 48 tubes fill in one action: no pipette tips, no tweezers required.
What seed sizes work with a 48-tube seed dispenser?
The 48 Tube Seed Dispenser accommodates seeds from 0.2 mm to 9.0 mm depending on the mesh plate installed. Exchangeable mesh plates let you switch between maize, soybean, tomato, and other species without replacing the dispenser frame.
How does a 48-tube seed dispenser improve germination throughput?
Manual loading of 48 individual tubes takes 3–6 minutes per rack. With the LabTIE dispenser, the same task is completed in under 30 seconds, freeing technician time for data collection and phenotyping rather than seed handling.
Can I use a 48-tube seed dispenser for Arabidopsis seeds?
The 48-tube format is generally used for larger seeds (>0.5 mm). For very small seeds like Arabidopsis thaliana, the 96-Well Arabidopsis Seed Dispenser with its fine mesh is better suited to the scale and seed size.
What is the best way to dispense seeds for DNA extraction using tube racks?
Dispense directly into 48-tube extraction racks for uniform seed number per tube. The <1% empty-tube error keeps tissue input consistent, reducing variation in DNA yield that would otherwise skew downstream genotyping.
How do I set up a 48-tube seed dispenser for plant breeding?
Assign each tray of seeds to a single variety, pull the slider for one rack per variety, and advance to the next tray. The tray design prevents cross-contamination between varieties without requiring disassembly between runs.
Can the 48-tube seed dispenser handle different rack formats?
The 48 Tube Seed Dispenser is matched to the 48-tube rack footprint. For 45-tube racks, 96-well plates, or 100-well trays, LabTIE makes dedicated dispensers, each engineered to seat precisely on its target container.
How accurate is the LabTIE 48-tube seed dispenser?
Under standard lab conditions the dispenser achieves <1% empty tubes. Accuracy depends on correct mesh plate selection for the seed size; using an over-large aperture is the most common source of double fills.
How do I clean a 48-tube seed dispenser between seed types?
Remove the mesh plate, invert and tap to clear remaining seeds, then rinse with 70% ethanol. For genetic isolation between GM and non-GM material, autoclave at 134 °C, 3 bar: all parts are autoclave-safe.
What are the shipping times for the LabTIE 48 Tube Seed Dispenser?
Standard units leave the Netherlands within 1–3 business days; EU parcels arrive in 2–5 days and international shipments in 5–10 days. Expedited shipping is available on request for time-sensitive planting schedules.
Do you offer custom mesh plates for the 48-tube dispenser?
Yes. Send a seed sample and LabTIE’s in-house technical division will produce a custom mesh plate matched to your seed size and tube inner diameter, usually within 5 working days.
Is the 48-tube seed dispenser compatible with cryogenic or deep-well tubes?
The dispenser is designed for standard 48-tube rack formats. For cryogenic tubes or deep-well configurations, provide your rack dimensions when requesting a quote so we can confirm seating clearance before ordering.
What is the best seed dispenser for a lab?
When your assay uses tube arrays rather than microplates, a tube-format dispenser is the appropriate choice. The LabTIE 48 Tube Seed Dispenser fills 48 tubes simultaneously in a single pass, handles seeds from 0.2 to 9 mm, and supports more than 120 species via interchangeable mesh plates. It is the standard choice for labs running pot-based germination trials or root phenotyping in tube racks.
Which manual seed dispensers are used in plant breeding research?
Breeding programmes that assess root architecture, stem elongation, or biomass in individual containers use tube-format dispensers to achieve uniform sowing density. The LabTIE 48 Tube Seed Dispenser delivers one seed per tube across all 48 positions simultaneously, eliminating the variability introduced by manual tweezers or hand-counting. It is used at seed companies and university phenotyping facilities where tube racks are the primary growth container.
What seed dispenser works best for Arabidopsis?
Arabidopsis thaliana is most often sown into microplates rather than tube arrays, but the LabTIE 48 Tube Seed Dispenser can handle Arabidopsis seeds when fitted with the correct mesh plate (0.2 to 0.5 mm aperture). For standard Arabidopsis work in 96-well or 48-well formats, the dedicated plate dispensers are more commonly specified. Contact LabTIE if your protocol requires single Arabidopsis seeds in individual tubes.
How do I choose the right seed dispenser for germination assays?
Choose the 48 tube format when your germination protocol requires individual containers with substrate depth greater than a microplate allows, such as soil columns or root observation tubes. The LabTIE 48 Tube Seed Dispenser loads all 48 tubes in one action and is validated for seeds from 0.2 to 9 mm. For plate-based germination assays, the 96-well or 48-well plate dispensers are more suitable.
What seed dispensers do genomics labs use for DNA extraction?
Genomics workflows that grow seedlings to the V2 or V3 leaf stage before extracting DNA sometimes use tube-format growth systems because tubes provide more root volume. The LabTIE 48 Tube Seed Dispenser ensures one seed per tube so that every DNA sample represents a single individual. For extraction from seedlings grown in 96-well plates, the 96-Well Seed Dispenser is the more standard instrument.
What should I look for when buying a seed dispenser?
For tube-format workflows, confirm that the dispenser grid matches your tube rack spacing and that mesh plates are available for your target species. The LabTIE 48 Tube Seed Dispenser is designed for 48-position tube arrays and supports seeds across more than 120 species. Also verify tube diameter compatibility: LabTIE can advise on fit during the quotation process.
Which seed dispenser is best for 96-well plate germination screening?
For 96-well plate germination screening, the LabTIE 96-Well Seed Dispenser is the purpose-built instrument. The LabTIE 48 Tube Seed Dispenser is optimised for tube-rack workflows where individual containers are required. If your germination screen uses 48 individual tubes rather than a microplate, this dispenser is the appropriate choice.
Are there manual seed dispensers that work with very small seeds like Arabidopsis?
Yes. The LabTIE 48 Tube Seed Dispenser supports seeds from 0.2 mm upward when the matching mesh plate is fitted. Arabidopsis and similarly fine seeds can be sown into individual tubes using this dispenser, provided the tube opening is sufficient to receive a seed of that size. For most Arabidopsis protocols in plate format, the dedicated 96-Well Arabidopsis Seed Dispenser is the more conventional choice.
