48 Tube Powder Dispenser for Auto-decapping Vials

Fill the dispenser body with your powder, level it with the scraper, place it on the loaded 48 tube rack and pull the slider once. All 48 tubes receive the same volume in the same motion.

Probably not, and this is the one thing to check first. The holder hole is Ø10.30 mm because the auto-decapping vial has a narrower body than the usual 2 mL microcentrifuge and cryogenic formats. A standard Ø10.80 mm 2 mL tube, and a Ø12.40 mm cryovial, will not enter it. See the table at the top of this page, and send your tube name or part number with your quote request: if it falls outside the Ø8.30 to Ø10.30 mm window we build the holder to your diameter.

The rack holds the ribbed tubes so they cannot rotate. That is what lets an automated de-capping robot unscrew all 48 caps, and it is also what keeps the tube openings under the mesh. The rack is mandatory for this format.

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.

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.

The LabTIE 48 Tube Powder Dispenser with Auto-Decapping removes tube caps automatically as part of the dispensing cycle: eliminating the need to manually uncap and recap each tube before and after dispensing. This fully integrated decapping and dispensing process maximises throughput and reduces operator handling time.

Load your powder compound into the dispenser reservoir, insert 48 capped tubes into the rack, and initiate the dispensing cycle. The auto-decapping mechanism removes caps, the mesh plate fills all 48 tubes simultaneously, and caps are replaced: all in a single, streamlined operation without any individual weighing.

The dispenser supports volumes from approximately 1 µL to 1500 µL per tube depending on mesh plate configuration. Multiple mesh sizes are available to match your target mass, accommodating a wide range of dispensing applications from low-dose compound distribution to larger quantity sample preparation.

LabTIE dispensers achieve less than 1% CV across all 48 tubes, ensuring highly consistent fills regardless of compound type. This accuracy eliminates the need for post-dispensing gravimetric verification in most research and pharmaceutical applications.

Yes: this dispenser is specifically designed for high-throughput compound distribution workflows in drug discovery. The combined decapping and dispensing functionality allows operators to process 48 tubes per cycle with minimal manual intervention, ideal for compound library management and sample reformatting.

The dispenser accommodates free-flowing dry powders including APIs, screening compounds, reference standards, and solid reagents. For cohesive or static-prone materials, LabTIE can provide guidance on mesh configuration and dispensing conditions to optimise performance with your specific compound.

Setup is fast and intuitive: load the appropriate mesh plate, fill the reservoir with compound, insert 48 capped tubes into the rack, and run the dispensing cycle. The auto-decapping mechanism is integrated into the dispensing stroke, so no additional tools or software are required.

By automating the decapping step that traditionally requires separate manual labour, this model reduces the total hands-on time per rack by an additional 30–50% compared to standard tube dispensers. The result is a fully automated fill-and-seal workflow for 48 tubes that takes only seconds per batch.

The mesh plate, reservoir, and decapping mechanism are all removable for cleaning with appropriate solvents. Thorough rinsing with ethanol or acetone followed by drying ensures complete compound removal between batches. Dedicated mesh plates per compound are recommended for GMP-regulated workflows.

Standard units are typically dispatched within 3–5 business days. Most European orders arrive within 1–2 weeks of dispatch. Contact LabTIE for express shipping or international delivery options specific to your location.

Yes: LabTIE can customise mesh plates for specific tube diameters, cap types, and target dispensing volumes. Contact the LabTIE team with your tube specifications and requirements, and they will recommend or manufacture the appropriate configuration.
