used to hold specimen or samples Sterile loops: used to inoculate test samples into culture media for bacterial or fungal cultures, antibiograms, etc.; not heated before use—these are disposable pre-sterilised Thermal cycler: used to amplify segments of DNA via the polymerase chain reaction (PCR) process. Tissue culture bottles
Fishtail points varied significantly in size and form, and many were likely hafted to spears, [2] [5] which were possibly used in combination with spear throwers, [3] though some are suggested to have served other purposes, like as knives or as cutting tools, and the same point may have been used for multiple functions.
Nessler cylinders are used for colorimetric analysis, such as APHA color. The color of the substance contained in a Nessler cylinder is visually compared with the model. The tubes often carry out a series of calibrations of solutions of increasing concentrations, which functions as a comparative scale.

[1] [2] [3] Before the mid-nineteenth century such tools were referred to as "natural philosophical" or "philosophical" apparatus and instruments, and older tools from antiquity to the Middle Ages (such as the astrolabe and pendulum clock) defy a more modern definition of "a ...

A Berlese funnel or Berlese trap is a device used to extract desiccation-intolerant invertebrates from samples of soil or leaf litter. It works by creating a desiccation gradient over the sample such that mobile organisms will move away from the dry environment and fall into a collecting vessel, where they are preserved for examination.
Pneumatic trough, and other equipment, used by Joseph Priestley. The bottle is filled with water, inverted, and placed into the pneumatic trough already containing water. The outlet tube from the gas-generating apparatus is inserted into the opening of the bottle so that gas can bubble up through it, displacing the water within. [4]
