Method for obtaining a fluid sample from a collection device which includes assembling cap and fluid-holding vessel components of the collection device to contain and isolate a specimen retrieval device adjacent a side wall of the vessel. The position of the specimen retrieval device within the collection device is such that the specimen retrieval device does not substantially interfere with the movement of a fluid transfer device into or out of the assembled collection device. The fluid transfer device is used to draw and remove a fluid substance from the collection device for analysis.

An optical fibre for transmission of light at a predetermined wavelength, the fibre having a core region, an inner cladding region and an outer cladding region, the inner cladding region having spaced apart voids, at least some of which are at least partly filled with a fluid substance to modify a refractive index in the cross-section of the fibre. The fluid substance may be introduced by preparing and fixing the fiber ends, identifying the voids to be filled and infusing the fluid therein while masking openings in the remaining voids. By selective heating of parts of the fibre, the location of the fluid substance in the void may be controlled to extend over only a fraction of the length of a void that extends the length by the fibre.

In addition, the actuatable toy comprises a flexible outer covering enclosing the deformable bladder, where at least a portion of the outer covering comprises a movable material disposed proximate to the actuatable component of the toy, whereupon actuating of the movable material and deformation of the bladder facilitate actuation of the actuatable component upon application of pressure on the toy.

This invention relates to a medical injection system for the intradermal injection of two or more fluid substances via micro-needles, and most preferably via a linear array of micro-needles, although the array need not be linear. Injecting two fluid substances contained in two separate chambers of the delivery device can be done by various methods. These methods may be generally categorized as, a) sequential injection, b) simultaneous injection, c) parallel injection and d) closed-loop injection processes. The present invention includes devices configured to perform all three of these methods.

An apparatus for mixing of liquid substances or distribution of solid substances in liquid substances in a plurality of sample containers arranged in a microplate (7) is supported on a horizontally displaceable support plate (2). A motor (3) that is provided with an unbalance is held via its stator (3A) above a base (1) directly on the underside of the support plate (2), the rotational axis (D) of the rotor (3B) being disposed perpendicular to the support plate (2). The support plate (2) with the motor (3) rests on at least three horizontally elastically movable bearing elements (6), whose points of attachment to the base (1) and to the support plate (2) are chosen such that the support plate (2) with the microplate (7) in the idle position assumes a specified position in the X-Y plane due to the reset force of the bearing elements (6), and in the shaking mode, as a result of the lateral, directionally identical deflection of the bearing elements (6) effected by the unbalance of the motor (3), performs a horizontal, non-torsional shaking movement against the reset force of the bearing elements. In the process, all sample containers of the microplate (7) describe an identical orbit in the X-Y plane and an identical energy for mixing is imparted to all sample containers.

This invention relates to a process and/or method and associated apparatus for use in spray freeze drying a fluid substance such as fruit juice, pharmaceuticals, nutraceuticals, tea and coffee. A fluid substance is sprayed (atomised) and reduces in temperature to below its eutectic temperature; thereby inducing a phase change of fluids in the fluid substance. The atomised fluid substance (AFS) is then subjected to a vacuumous drying chamber in which the AFS is subjected to an energy source to assist sublimation of fluid from the AFS as it is conveyed through the chamber. Such an energy source can provide a temperature gradient through which the AFS passes and is exposed to, all carried out so as to preferably minimise or reduce the likelihood of degradation of the substance being dried (reducing the fluid content).
