Product Description
Preserving intact nuclei and mitochondria during homogenization depends on gentle, controlled shear. Dounce grinders retain a high percentage of these organelles from soft tissues and cell cultures, making them a standard tool for subcellular fractionation in cell biology and biochemistry labs.
This listing is for Wheaton catalog number 357544: Dounce Tissue Grinder, 15 mL, Case of 2. Each set is borosilicate glass 3.3 and includes both loose and tight pestles, with clearances of 0.089 to 0.14 mm and 0.025 to 0.076 mm. The ball of the pestle stays surrounded by liquid, reducing friction and heat build-up. The tube has a large reservoir and pouring lip, and units can be autoclaved. Sizes are 1, 7, 15 and 40 mL. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
Key Features
- Organelle preservation – Retains nuclei and mitochondria.
- Loose and tight pestles – Two clearances in each set.
- Low heat build-up – Liquid around the pestle reduces friction.
- Pouring lip – Large reservoir eases decanting.
- Autoclavable – Prevents cross contamination.
