For example, a blue-top tube is a 5 ml test tube containing sodium citrate as an anticoagulant, used to collect blood for coagulation and glucose-6-phosphate dehydrogenase testing. [5] Small vials used in medicine may have a snap-top (also called a hinge cap) molded as part of the vial.
The 1 well rack is designed to hold only one test tube or any tube that fits in the space. It is normally made of epoxy-coated steel wire [ 6 ] but can also be made of polystyrene. The racks made from polystyrene are friction-fit and can only hold tubes that match in size to the rack.
The load in a laboratory centrifuge must be carefully balanced. This is achieved by using a combination of samples and balance tubes which all have the same weight or by using various balancing patterns without balance tubes. [2] It is an interesting mathematical problem to solve the balance pattern given n slots and k tubes with the same weight.
A laboratory rubber stopper or a rubber bung or a rubber cork is mainly used in chemical laboratories in combination with flasks and test tube and also for fermentation in winery. [ 1 ] [ 2 ] [ 3 ] Generally, in a laboratory , the sizes of rubber stoppers can be varied up to approximately 16 sizes and each of it is specific to certain type of ...
It is used for holding a test tube in place [2] when the tube is hot or should not be touched. [3] For example, a test tube holder can be used to hold a test tube while it is being heated. [4] Moreover, when heating the tube with liquid or solid contained inside, the holder ought to tightly hold a test tube [5] in order for the tube to be ...
