Abstract
A tamper for making paraffin blocks for histology may include a pliable tamper head and a handle. The handle may be permanently or removably attached to the tamper by using screws, magnets, or the like. The tamper may be made from a pliable material, such as a silicone rubber, with improved thermal transfer and high latent heat. In use, the tamper may be warmed in advance to a working temperature by placing the tamper on a hot plate of the embedding station or on a dedicated smaller hot plate. Alternatively, the tamper may be heated with an electric resistive element, a thermoelectric device, or an electric induction coil.
Claims17
A tamper for embedding one or more biological tissue samples, the tamper comprising:
- a pliable tamper head;
- at least one handle configured to couple to the pliable tamper head;
- and
- a handle coupling for coupling the at least one handle to the pliable tamper head, wherein the pliable tamper head comprises an amount of a phase change material mixed with an amount of a silicone rubber material, wherein the phase change material comprises a fatty acid or an amount of a wax material or both.
A tamper for embedding one or more biological tissue samples, the tamper comprising:
- a pliable tamper head;
- at least one handle configured to couple to the pliable tamper head;
- and
- a handle coupling for coupling the at least one handle to the pliable tamper head, wherein the pliable tamper head comprises an amount of a phase change material mixed with an amount of a silicone rubber material, wherein the silicone rubber material comprises at least one of:
- at least one metal mixed with the silicone rubber material, an amount of graphite mixed with the silicone rubber material, or an amount of ceramic material mixed with the silicone rubber material.
A tamper for embedding one or more biological tissue samples, the tamper comprising:
- a pliable tamper head;
- at least one handle configured to couple to the pliable tamper head;
- and
- a magnetic handle coupling for coupling the at least one handle to the pliable tamper head, wherein the pliable tamper head comprises an amount of a phase change material mixed with an amount of a silicone rubber material.
A tamper for embedding one or more biological tissue samples, the tamper comprising:
- a pliable tamper head;
- at least one handle configured to couple to the pliable tamper head;
- and
- a handle coupling for coupling the at least one handle to the pliable tamper head, wherein the pliable tamper head comprises an amount of a phase change material mixed with an amount of a silicone rubber material,
- wherein the pliable tamper head comprises:
- a lower layer having a first thermal conductivity;
- a core having a specific latent heat;
- and
- a peripheral layer having a second thermal conductivity, wherein the first thermal conductivity is higher than the second thermal conductivity.
A tamper for embedding one or more biological tissue samples, the tamper comprising:
- a pliable tamper head;
- at least one handle configured to couple to the pliable tamper head;
- and
- a handle coupling for coupling the at least one handle to the pliable tamper head, wherein the pliable tamper head comprises an amount of a phase change material mixed with an amount of a silicone rubber material, wherein the phase change material is encapsulated in a polymer material or is absorbed in a porous matrix or both.
