arrow12Tissue Grinders

Wheaton Tissue Grinders enable primary cells to be prepared from excised tissues, as well as sub-cellular components from harvested cell packs. Tissue grinders are used to extract DNA, RNA and proteins for blot or other procedures. They are also used to enhance recovery of other cell products. Capacities on the grinders range from 0.1 ml to 55 ml. There are many grinders to suit your needs.

  • Tapered Tissue Grinders are ideal for connective tissue including heart, muscle, and lung. These glass-on-glass grinders feature a long taper design that minimizes grinding efficiency.
  • Potter-Elvehjem Tissue Grinder incorporates a serrated pestle design to disperse homogenate into the mortar cylinder. Standard unit with Teflon® pestles are well suited for soft tissue, such as brain and liver.
  • Tenbroeck Tissue Grinders have a hollow handle that allows packing with ice, making them suitable for tissues such as liver, intestines and heart.
  • Dounce Tissue Grinders are supplied with two types of pestles: a loose-fitting pestle for sample reduction and a second, tighter pestle for complete homogenization. The ball-shaped pestles leave cell nuclei intact in soft tissue.
  • The Wheaton Micro Tissue Grinder Kit offers a complete selection of micro tissue grinders.
  • All Wheaton tissue grinders are manufactured from Wheaton 33 low extractable borosilicate glass that conforms to USP Type 1 and ASTM E-438 Type 1, Class A requirements. Replacement parts can be purchased separately.

arrow12Dounce Tissue Grinder

  • Ideal for soft tissue
  • Provide with loose and tight pestle
  • Wheaton 33 low extractable borosilicate glass
  • Autoclavable.

This grinder designed to retain a high percentage of cell nuclei and mitochondria in soft tissues from cell cultures. When use, the pestle ball is encircled in liquid, which is avoid heat buildup by reducing friction. This grinder is ideal for enzyme studies. The initial grinding is performed using the “loose" pestle. The grinding process is completed using the “tight" pestle.. This grinder is used by moving the pestle up and down, and work best with cell suspensions or very soft tissues. The mortar has a large reservoir and pouring lip and is supplied with “loose" and “tight" pestles.

Tight Pestle “A" Specification: 0.0010 – 0.0030" (0.025 – 0.076 mm) Loose Pestle “B" Specification: 0.0035 – 0.0055" (0.089 – 0.14 mm)

arrow12Potter-Elvehjem Tissue Grinder

  • Ideal for tissue homogenates
  • Use with power homogenization
  • Parts interchangeable
  • Teflon® pestle
  • Autoclavable

These grinder are precisely constructed with completely interchangeable parts to allow easier cleaning or replacement of damaged mortars. They are designed for use in preparation of tissue homogenates and other similar applications. The Teflon pestle is for soft tissues such as brain or liver. The stainless steel rod is 0.25" (6.3mm) diameter. The grinding chamber clearance is 0.004" to 0.006’ (0.1 to 0.15mm). This unit is autoclavable and can be used for power homogenization as with overhead stirrer. However, we strongly recommend the use of safety-coated tissue grinder (64793-series) for added safety.

Homogenizes connective tissue including heart, muscle and lung

  • Made from Wheaton 33 low extractable borosilicate glass
  • Interchangeable components takes the hassle out of matching parts
  • Autoclavable

This is new design grinder with longer tapered surface on both the mortar and pestle, offering grinding more efficient and less time require. The conical surface allows initial size reduction followed by passage through the cylindrical section for the final homogenization step.

When the pestle is “bottomed" within the mortar, the clearance is uniform 0.004" to 0.006" (0.1 to 0.15 mm)

The components are interchangeable. Therefore no need keep parts matched during cleaning. The ground glass surface on both the mortar and pestle are capable of homogenizing connective tissue such as heart, muscle and lung, as well as skin and plant tissue.
