The powder dispenser range
Ten standard formats from 24 tubes to 384-well plates, plus custom builds and extra mesh plates.
Fill, slide, done
What researchers say
“The 45 tube Powder Dispenser arrived quickly and was extremely well packaged. Everything works exactly as stated, and our bottlenecks are practically eliminated. It paid for itself in a single week.”
“The ability to quickly and reproducibly dispense volumes is priceless. The interchangeable mesh plates make changing volumes quick, and there is far less aerated powder than dispensing by hand.”
“I previously dispensed beads by hand, which was imprecise and time consuming. Now we use a 96 well format with the Dispenser Kit, and the LabTIE team tailored the setup to our exact science.”
Precision powder dispensing for life science laboratories
LabTIE powder dispensers dose 10 to 1000 microliters of powder into vials, tubes and microplates in about 45 seconds, replacing manual weighing on a balance. Used across pharma, HPLC sample preparation, DNA and RNA extraction, and proteomics workflows, they deliver repeatable doses at every position on a plate or rack.

Why powder dosing by hand falls short
Weighing powder into every vial or well by hand is slow and introduces variability between samples. Static, humidity and operator technique all change the amount that ends up in each container, which makes results harder to compare across a run. As sample counts grow, from 24 tubes to a full 384 well plate, manual weighing becomes the bottleneck in the workflow.
How a mesh plate dispenser works
A LabTIE powder dispenser uses an exchangeable mesh plate sized to the dose you need. You fill the reservoir, place the dispenser onto your vials, tubes or wells, and slide it once. Every position receives the same volume in the same motion, in about 45 seconds for a full plate or rack. Changing formats or doses is as simple as swapping the mesh plate.
Where powder dispensers are used
Pharmaceutical formulation and quality control. HPLC and GC vial sample preparation. DNA and RNA extraction workflows. Food, soil and environmental testing.
Standard formats and custom builds
LabTIE offers powder dispensers for 24, 45, 48, 96 and 384 well and vial formats, ready to buy directly. For containers outside those standards, our own tech division builds a custom mesh plate and converter around your exact vial, tube rack or plate.
Get the right dispenser for your lab
Whether you dose ten samples a week or run full plates daily, a LabTIE powder dispenser removes the balance from your workflow and gives you a dose you can trust, every time.
Frequently asked questions
What is a LabTIE powder dispenser and how does it work?
A LabTIE powder dispenser is a manual precision instrument that fills every well, tube or vial in a rack with the same dose of dry powder in one dispensing stroke, without weighing. A mesh plate matched to your target volume holds an identical amount of powder above each position; pulling the slider drops the dose into all positions at once, filling a full plate or rack in about 45 seconds with less than 1% CV.
What volume range do LabTIE powder dispensers handle?
LabTIE powder dispensers dispense from 10 µL up to 1000 µL per position. Each target volume has its own interchangeable mesh plate, so one dispenser body covers multiple volumes: you select the model and mesh plate based on your dose and container format.
How accurate are LabTIE powder dispensers for laboratory use?
All LabTIE powder dispensers achieve less than 1% coefficient of variation (CV) across dispensed positions, without gravimetric verification. This accuracy is validated across a broad range of compound types and volumes, making the dispensers suitable for pharmaceutical, analytical and drug discovery applications.
Can a manual powder dispenser replace weighing on a balance?
Yes. For routine volume-based dosing, a LabTIE powder dispenser replaces the balance entirely: select the mesh plate for your target volume and pull the slider once, and every position receives the same calibrated dose with less than 1% error. For primary screening, reagent distribution and compound library loading this removes the balance as the main bottleneck in sample preparation.
What container formats do LabTIE powder dispensers support?
LabTIE builds dedicated powder dispensers for 96-well and 384-well microplates, 48-well plates, 24-tube and 45-tube racks, 48-tube racks including auto-decapping vials, 2 mL GC autosampler vials and snap-cap tubes. Custom dispensers are available for proprietary or non-standard containers such as PCR strips, beakers and 15 or 50 mL centrifuge tubes.
What types of powder can be dispensed with LabTIE dispensers?
LabTIE dispensers handle a broad range of dry powders: APIs, solid compound libraries, excipients, reference standards, solid reagents and natural compounds. Performance is optimised for free-flowing powders; for cohesive or hygroscopic materials LabTIE advises on the right mesh configuration.
How do I choose the right powder dispenser for my lab?
Start with your container format (96-well, 384-well or 48-well plate, tube rack, or GC-vial rack), then your target volume within the 10 to 1000 µL range. Also check dispensing reproducibility (LabTIE: less than 1% error) and whether you want to dose without a balance. Interchangeable mesh plates let one dispenser body cover multiple volumes, so a single unit can serve several assay conditions.
Which powder dispenser is best for high-throughput compound screening and drug discovery?
The LabTIE 96-well and 384-well powder dispensers offer the highest plate-per-hour throughput for screening, because each slider pull fills an entire plate simultaneously. They are widely used in drug discovery for compound library preparation, sample reformatting, HTS plate loading and fragment library distribution, cutting plate preparation time by up to 95% compared with manual weighing.
What is the difference between a 96-well and a 384-well powder dispenser?
The 96-well dispenser fills standard 96-well microplates with larger per-well volumes, ideal for assay development and standard screening. The 384-well dispenser targets the denser 384-well format with smaller per-well volumes, including material finer than 0.3 mm, optimised for high-throughput screening and library miniaturisation. Accuracy and operation are identical.
How do I set up a LabTIE powder dispenser?
Setup takes minutes and needs no software or power supply: select the mesh plate matching your target volume, pour your compound onto the mesh, scrape off the excess, place the dispenser on your plate or rack, and pull the slider once. All LabTIE dispensers are immediately operational with minimal training.
Can I order custom mesh plates or a fully custom powder dispenser?
Yes. LabTIE manufactures custom mesh plates for all standard models and designs fully custom dispensers for non-standard containers. Provide your target volume, container format and powder characteristics, and LabTIE supplies matched mesh plates or a bespoke dispenser solution.
What are the shipping times for LabTIE powder dispensers?
LabTIE ships worldwide from the Netherlands. Standard powder dispensers are typically dispatched within 3 to 5 business days of order confirmation, and most European deliveries arrive within 1 to 2 weeks. Express shipping is available on request; custom dispensers may have longer lead times depending on design complexity.
Do LabTIE powder dispensers come with a warranty?
Yes. LabTIE dispensers are covered by a 12-month manufacturer’s warranty against defects in materials and workmanship under normal laboratory conditions. Contact LabTIE customer service for full terms, service options and after-sales support.
