MUHWA 28-Hole Circular Pipette Stand — Rotating Acrylic Pipette Carousel for Serological and Volumetric Pipettes
MUHWA 28-hole circular pipette stand provides organized, space-efficient storage for up to 28 serological, volumetric, or transfer pipettes in a compact rotating carousel format. The clear acrylic construction offers full 360° visibility of all pipettes at a glance. The carousel rotates smoothly on its base, bringing any pipette within easy reach without moving the stand. With two concentric rings (outer: 25–50 mL pipettes, inner: 1–10 mL), the stand accommodates a complete range of pipette sizes used in tissue culture, microbiology, and chemistry workflows. The 180 mm height keeps pipette tips elevated above the bench, protecting them from contamination. The weighted base prevents tipping even when fully loaded. Chemical-resistant to 70% ethanol for routine decontamination.
Key Features
- 28 Pipette Positions — Two concentric rings: 16 outer holes for 25–50 mL pipettes, 12 inner holes for 1–10 mL pipettes. Accommodates the full range of serological and volumetric pipettes.
- 360° Rotating Carousel — Smooth-rotation base mechanism for one-handed pipette selection. Spin to bring the desired size to the front without reaching across other equipment.
- Crystal-Clear Acrylic — Full transparency provides instant visual inventory. See at a glance which sizes need restocking. Maximizes light transmission in biosafety cabinets.
- Weighted Stable Base — Wide circular base with low center of gravity prevents tipping even when fully loaded with heavy 50 mL glass pipettes.
- 180 mm Elevated Height — Keeps pipette tips above the work surface, reducing contamination risk. Ergonomic height for insertion and retrieval.
- Chemical-Resistant, Easy to Clean — Withstands routine decontamination with 70% ethanol or isopropanol. Smooth, non-porous surface wipes clean in seconds.

Applications
- Tissue Culture and Cell Culture — Keep sterile serological pipettes organized inside biosafety cabinets. Clear acrylic does not obstruct HEPA airflow or lighting.
- Microbiology Workflows — Centralized pipette storage for media prep, culture inoculation, and dilution series in laminar flow hoods.
- Clinical and Diagnostic Labs — Shared pipette station for specimen processing and reagent preparation. Rotating design enables multiple technicians to access from different angles.
- Teaching Laboratories — Organized, visible storage for student pipettes. Easy identification of correct sizes without handling multiple pipettes.
Frequently Asked Questions
Q: Can this stand be autoclaved?
A: No. Acrylic (PMMA) warps at autoclave temperatures. For surface decontamination, wipe with 70% ethanol or isopropanol.
Q: Will 50 mL pipettes be stable?
A: Yes. The weighted base and 180 mm height provide adequate stability. In high-vibration environments, the tallest pipettes may sway slightly but will not tip.
Q: Does the rotation mechanism wear out?
A: The simple friction-fit design has no bearings or springs to fail. If rotation becomes stiff, a light silicone lubricant on the base contact surface restores smooth movement.
Q: Glass and plastic pipettes both compatible?
A: Yes. The hole diameters accommodate both glass and disposable plastic serological pipettes without issue.
