An apparatus for micromanipulation of biological material, includes a vessel (1) having a reservoir (2) wherein the vessel has a channel (3) formed in a portion of the reservoir, the channel including an intermediate restriction (4) dimensioned to resist passage of the biological material but allow passage of liquid treatment solutions.

A bodily fluid transporting unit that includes a container with a syringe housing and a refrigerant pack in the container. The container is covered by a lid and the engagement of the container and the lid results in an air-tight and moisture-tight bodily fluid transporting unit.

A method of cryopreservation of biological material includes the steps of providing an apparatus including a vessel having a reservoir wherein the vessel has a channel formed in a portion of the reservoir, the channel including an intermediate restriction dimensioned to resist passage of the biological material but allow passage of liquid treatment solutions, and the channel including sub-reservoirs at either end of the restriction; introducing the biological material into a reservoir region of the apparatus for capture in a channel region of the vessel; irrigating and draining the biological material with a series of vitrification solutions introduced into a first of the sub-reservoirs and removed from a second of the sub-reservoirs; final draining the irrigation solutions from the vessel; and vitrifying the vessel and captive biological material.

An apparatus for treating spermatozoa of an animal to increase motility includes: a holding or mounting unit configured to hold or support a sperm container; a lighting unit configured to irradiate the sperm container held or supported by the holding or mounting unit with light having wavelengths in a range of 390-420 nm; and a light controller unit configured to control the lighting unit.

A bodily fluid transporting unit that includes a container with a syringe housing and a refrigerant pack in the container. The container is covered by a lid and the engagement of the container and the lid results in an air-tight and moisture-tight bodily fluid transporting unit.

Designs of improved canisters for animal semen straw storage in Dewars with cryogenic liquid are described. In some embodiments, the canisters include a layer of cryogen-absorbent material and an inner layer of thermally conductive material including apertures oriented and positioned to direct cryogen vapor into the interior of the container.

The straw includes a tube (11) extending between a first end (16) and a second end (17) and includes a gas-permeable but liquid-impermeable plug (12). The tube (11) is made of a thermochromic material that reversibly changes colour at a preset temperature threshold, by virtue of which colour change the tube (11) has a first visual appearance if the temperature thereof is below said preset threshold and a second visual appearance that is different from the first visual appearance if the temperature thereof is above said preset threshold.

The present invention relates to a device and method for collecting semen from boars. The device is characterized in that it has a simple structure and is therefore inexpensive to produce and, during the method, it reduces contamination, in particular the microbe count. The device has a glove (1) with a fingers portion (2) and a thumb portion (3) for receiving a hand and, on one side of the glove (1) between the fingers portion (2) and the thumb portion (3), it has a film tube (5) with an opening (6) which is held open by a spring element (10), and of which the opposite, second end (13) is closed, wherein the film tube (5) is connected to the glove (1).
