Design + fabrication · Miami, Florida

Custom laboratory & research equipment accessories

Custom racks, holders, adapters, and apparatus supports for research workflows that standard accessories do not fit. Miami Makes develops the physical interfaces around your samples, instruments, and experimental procedure.

Your project, in practical terms

From requirement to finished part.

Example requests show how design, fabrication, and delivery can fit together around your needs.

Can you make a rack for unusual sample tubes that fits our instrument or work area?

Miami Makes can design a custom tube or vial rack with the required pocket diameter, depth, spacing, identification, and loading access. Machined plastics or printed constructions can accommodate nonstandard vessels, mixed sizes, or a constrained instrument footprint. We can develop the CAD from vessel dimensions or samples, make a trial rack for fit and workflow review, and produce additional racks for nationwide shipment.

Where we start. Send vessel dimensions including tapers and flanges, the number of positions, available space, and instrument clearance. Specify cleaning agents, temperature, and sterilization needs before choosing a material; the design can be evaluated against your actual cleaning and handling procedure.

Applications & construction options

Built around your use.

Explore materials, dimensions, and details for each application. Dimensions below describe example configurations, not fixed limits or guaranteed specifications. We develop the final construction around your requirements.

01

Nonstandard vial & tube racks

Hold unusual containers or mixed sample formats in a consistent arrangement.

Materials & fabrication
Machined HDPE, polypropylene, or acetal for compatible exposures; printed racks for suitable ambient work; aluminum supports where the thermal or structural need warrants them.
Dimensions & construction
Define vessel diameter, taper, flange clearance, pocket depth, row spacing, labels, and finger access. Layered or adjustable racks can accommodate different heights.
What determines the choice
Specify chemicals, cleaning, working temperature, transport, and tipping risk. Freezing, autoclaving, or sterile use requires a material and construction selected for that process.
02

Sample holders & cuvette supports

Position samples without obstructing the area under observation or measurement.

Materials & fabrication
Machined acetal or aluminum holders, printed inserts, and contact pads compatible with the sample. Surface finish can be chosen for the optical setup.
Dimensions & construction
Develop datum faces, apertures, clamps, angular references, and access for loading. Contact only the permitted surfaces and provide relief for fragile edges.
What determines the choice
Check light paths, reflections, contamination, thermal effects, and clamp distortion. Sample identity and repeat loading position should remain clear through the procedure.
03

Instrument adapters

Connect components with mismatched footprints, heights, or mounting patterns.

Materials & fabrication
CNC-machined aluminum or engineering plastics with purchased fasteners, inserts, and interface hardware. Printed fit models can confirm access.
Dimensions & construction
Define hole patterns, thread engagement, offsets, alignment references, and clearances from both instruments. Adapter plate thickness follows stiffness and available mounting depth. Directly tapped metric or imperial threads can match the instrument interface, including M4/M6 and 1/4-20 mounting patterns. Confirm the actual thread pitch, screw length, and available engagement rather than treating similar nominal sizes as interchangeable.
What determines the choice
Review loads, vibration, grounding or isolation, cooling, and manufacturer interface requirements. Ensure the adapter does not obstruct controls, vents, or service points.
04

Probe-positioning fixtures

Hold sensors and probes at a repeatable location relative to a sample.

Materials & fabrication
Aluminum frames, acetal clamps, printed shaped supports, and purchased adjustment slides or articulated mounts.
Dimensions & construction
Specify height, angle, approach travel, clamp diameter, and locking method. Add stops and reference markings for repeated setup.
What determines the choice
Probe force, cable pull, vibration, drift, and sample motion can change the result. Required positional stability determines whether printed supports or machined construction are appropriate.
05

Imaging stages & optical supports

Present specimens or components consistently to a camera or microscope.

Materials & fabrication
Machined aluminum or acetal bases, matte-finished inserts, and printed sample-specific nests. Purchased motion components can supply controlled adjustment.
Dimensions & construction
Include optical access, illumination openings, orientation keys, adjustment travel, and repeatable mounting. Height follows focus range and working distance.
What determines the choice
Check glare, shadows, vibration, background contrast, and interference with objectives. A sample holder must suit the complete imaging and illumination arrangement.
06

Laboratory tubing organizers

Route flexible lines and keep connections identifiable and accessible.

Materials & fabrication
Printed polymer guides, machined HDPE or acetal blocks, and compatible soft retainers. Clips can be replaceable for different tubing diameters.
Dimensions & construction
Define outside diameters, minimum bend radii, labeling, spacing, and access to disconnect a single line. Split holders can avoid threading connectors through closed holes.
What determines the choice
Review solvent exposure, cleaning, pinch pressure, temperature, and contamination control. Retention must not restrict flow or transfer excessive force to fragile fittings.
07

Experimental apparatus supports

Assemble a physical setup for a defined research procedure.

Materials & fabrication
Aluminum profiles or plates, machined polymer fixtures, printed adapters, and purchased clamps, slides, and fasteners.
Dimensions & construction
Develop mounting grids, adjustable supports, removable modules, and reference marks. Footprint and access follow the instrument arrangement and operator sequence. M4–M8 heat-set inserts in suitable thermoplastic modules can connect adjustable brackets and removable supports to a common base; use the actual metric or imperial thread specified by the apparatus.
What determines the choice
Define loads, liquids, heat sources, motion, and measurement sensitivity. Pressure, hazardous chemistry, electrical safety, and biological containment remain explicit system-design requirements.

Design is part of the engagement

Help defining it.
Help making it.

We translate the experimental or handling procedure into defined physical interfaces. Samples, instrument drawings, and a workflow description can be enough to begin a rack, adapter, fixture, or apparatus design.

Design and documentation can stand alone, continue through our fabrication work, or support production by a specialist facility.
