45 Tube Powder Dispenser

Fill the dispenser body with your powder, level it with the scraper, place it on the loaded tube rack and pull the slider once. All 45 tubes receive the same volume in the same motion.

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.

Yes. Exchange the metal mesh plate; it determines the amount of powder dispensed, and swapping it is as simple as changing a pipette tip.

Yes, indirectly. Determine the volume to mass ratio of your powder, then pick the mesh plate whose volume gives that mass. Send us a sample and we will determine it for you: moc.eitbal@ofni.

Within a 2% error range for any homogeneous powder. Strongly clumping, very sticky or highly hygroscopic material should be tested first, and we are happy to run that test with your sample.

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.

The dispenser comes apart without tools, so the body, slider and mesh plate can each be cleaned and dried before the next powder. Full guidance is in the instruction manual.

Shipping is world wide with DHL Express and takes 7 to 20 working days. Custom racks and mesh plates take longer because they are made to your specification.

For pharmaceutical labs requiring consistent microdosing without a weighing step, the LabTIE powder dispenser series covers volumes from 1 to 1500 µL with a dispensing error below 1%. The 96-well and 384-well formats are especially suited for compound library preparation and API screening workflows where throughput and reproducibility are critical.

Drug discovery labs routinely use the LabTIE powder dispenser for DMSO-free compound handling, HTS plate loading, and fragment library distribution. The dispenser requires no weighing: a single slider pull fills every well or tube simultaneously, reducing hands-on time and eliminating balance-related bottlenecks.

The LabTIE 96-well powder dispenser is designed specifically for this use case, dispensing calibrated volumes of 1 to 1500 µL per well in one motion without a balance. Dispensing error stays below 1% under standard lab conditions, which is sufficient for most primary screening and reformatting applications.

Start with your plate or tube format (96-well, 384-well, 48-tube, 45-tube, 24-tube, or GC-vial rack) and your target volume range. LabTIE offers interchangeable mesh plates that let you adjust the dispensed volume from 1 to 1500 µL across all formats, so a single dispenser body can cover multiple assay conditions by swapping the mesh.

Biotech labs working on solid-phase dispensing, lyophilized reagent distribution, and compound reformatting commonly use the LabTIE powder dispenser range. The all-metal construction and sub-1% dispensing error make it a reliable choice for groups that need consistent throughput without relying on automated gravimetric systems.

Key criteria include format compatibility (well plate vs. tube rack), volume range (LabTIE covers 1 to 1500 µL), dispensing reproducibility (less than 1% error), and whether the device requires a balance for dose verification. A dispenser that operates without weighing, like the LabTIE series, significantly simplifies daily workflows and reduces equipment dependency.

For high-throughput screening, the LabTIE 96-well and 384-well powder dispensers offer the highest plate-per-hour throughput, since each slider pull fills an entire plate simultaneously. Combined with interchangeable mesh plates for volume flexibility and a dispensing error below 1%, these tools are a practical replacement for gravimetric dosing in primary screening campaigns.

In many routine sample prep workflows, yes. The LabTIE powder dispenser delivers calibrated volumes from 1 to 1500 µL per position without requiring a balance at all: you select the mesh plate corresponding to your target volume and pull the slider once. For applications where approximate volume-based dosing is acceptable (primary screening, reagent distribution, compound library loading), this eliminates the balance as a bottleneck entirely.
