Description
- This nonprovisional application claims the benefit of the U.S. provisional application 62/061,019 filed on Oct. 7, 2014. The disclosure of all applications are incorporated by reference in their entirety herein this reference.
- The present invention relates to a mold for making a tool out of ice, wherein the tool is a test tube rack. The mold has one or more walls and a base or unitary construction that form a compartment capable or retaining liquid. The mold may be filled with liquid and said mold may be placed inside of a freezer where said liquid is frozen into a shape capable of holding test tubes in an organized manner. The test tube rack made out of ice has a plurality of holes that are of appropriate size for the insertion of test tubes. The ice test tube rack assists a user in maintaining organization of samples when performing scientific experiments while also maintaining samples at a cold temperature.
- When performing research in the field of biological sciences it is of utmost importance to maintain a high level of organization. One of ordinary skill in the art knows that biological research experiments often involve the use of multiple test tubes, thus necessitating a suitable level of organization so as to prevent potential confusion and loss of track of samples held within the test tubes. Maintaining organized samples minimizes mistakes and provides for efficient and successful research.
- Biological research experiments often require that samples be maintained at a cold temperature, preferably near freezing. For example, samples containing biological tissues or cells, enzymes, bacteria, viruses or a mixture thereof commonly require to be kept at a low temperature during the entirety or a portion of a particular research experiment. Also, various experimental protocols require that samples be incubated at a cold temperature for a predetermined amount of time. For example, experiments involving specific enzyme reactions, such as ligation reactions performed with T4 DNA Ligase, include an incubation step at 15° C. for four to eight hours or 4° C. for overnight. Another example of an experiment where a low temperature is required are bacterial transformations, which require a 20 to 30
minute 4° C. incubation step, with a subsequent twominute 4° C. incubation step. Antibody labeling protocols, for example antibody labeling of cells for flow cytometry, require several steps where samples are incubated at 4° C. Thus, maintaining biological samples within a cold environment is at times necessary for the preservation of viability and biological activity of a sample, and for the success of an experiment. - When performing research with potentially dangerous pathogens, one of ordinary skill in the art may perform an experiment or a portion of an experiment in a biological safety cabinet. Biological safety cabinets are partially enclosed systems with a ventilated workspace. Biological safety cabinets are kept at sterile or near sterile conditions so as to prevent contamination of the experiment being performed, as well as to prevent a researcher from being exposed to potentially dangerous pathogens that are used within the biological safety cabinet.
- Cleaning and decontamination of a biological safety cabinet prior to, at times during, and after performing an experiment within the cabinet is highly important for the success of an experiment as well as for the safety of the researcher and members of the research facility. Cleaning and decontamination of a biological safety cabinet often involves spraying the interior of the cabinet with a disinfectant, such as a 20% ethanol solution, a 10% bleach solution, or a commercially available disinfectant such as CaviCide™.
- Any research tool or item placed inside of the biological safety cabinet is also subjected to cleaning with a disinfectant before and after use. Any solid waste generated during an experiment in a biological safety cabinet is often collected in a biohazardous waste trash bag, and is then removed from the cabinet after exterior decontamination of the bag. Liquid waste generated during an experiment performed within a biological safety cabinet is often collected into a bottle or poured into a bucket that has been partially filled with a disinfectant, for example the bucket may be partially filled with a 10% bleach solution. Because various items and research tools used within a biological safety cabinet are often moved from the inside to the outside of the cabinet, proper decontamination of said items is important so as not to expose and endanger personnel to dangerous pathogens used within the cabinet.
- Decreasing the number of items that are placed inside of a biological safety cabinet that later have to be disinfected and reused helps minimize exposure to potential pathogens. For example, disposable plastics such as pipet tips and petri dishes are commonly used during research and are used within biological safety cabinets. Following the use of disposable plastics in a biological safety cabinet the items are placed inside a biohazardous waste bag and then properly disposed of. However, there are various items and tools used in biological research that are not disposable, such as pipets and reusable tools. Non disposable items used within a biological safety cabinet require thorough decontamination and cleaning so as not to transfer harmful pathogens outside of the cabinet. Even though necessary decontamination steps are often applied to items removed from a biological safety cabinet, users of said items may be uneasy with regards to the cleanliness of recently removed items. Carelessness and improper decontamination during the removal of items used within a biological safety cabinet may potentially put researchers and laboratory personnel at risk of infection by a harmful pathogen.
- Therefore, there is a need for research tools that can be easily and thoroughly decontaminated following their use inside of a biological safety cabinet that are also disposable. The invention as described herein allows a user of ordinary skill in the art to make a test tube rack out of ice that is easily disposable. The test tube rack may be used within a biological safety cabinet to assist a user in organizing samples during an experiment while at the same time keeping samples at a low temperature. After the completion of the experiment, the user may easily dispose of the ice test tube rack by placing the said rack into a liquid waste bucket, wherein the ice test tube rack melts and is then treated as liquid waste.
- While there are various designs of ice cube trays, there are no ice cube trays that have been designed to make ice in the shape of a tool for use in biological research, wherein said tool may hold test tubes. The present invention relates to a mold for making a tool out of ice that is shaped to hold a plurality of test tubes. More particularly, the mold comprises of one or more walls and a base of unitary construction. Preferably the mold is made of an elastic material. The mold is shaped to have a compartment that may be filled with water. The mold with water in the compartment may be placed into an environment capable of freezing liquid, wherein the liquid may be water. The mold has a plurality of equidistant protrusions extending from an upper surface of the base. The protrusions displace said liquid, whereupon placing the kit into a freezer for a time appropriate for freezing the entirety of said liquid, said liquid freezes within the confines of the compartment and around the protrusions. The frozen liquid is removed from the mold creating a test tube rack made out of ice, wherein the test tube rack has a plurality of holes and each hole has a shape capable of accommodating a test tube. Test tubes may be placed within the holes, allowing for proper organization as well as continuous cooling of the test tubes during an experiment.
