Scigen offers a variety of clinical specimen containers to collect, hold, transport, and stabilize general clinical specimens. Choose from a wide variety of sizes, materials and compositions. Prefilled formalin and tissue specimen containers are available for convenient, safe storage and retrieval of pathology samples. These impact-resistant, clear polypropylene jars are filled with 10% neutral, phosphate-buffered formalin. Prefilled Formalin Specimen ContainersPrefilled formalin specimen containers provide a convenient way to store and transport tissue samples. These jars are filled with 10% neutral buffered formalin and have a ribbed, leakproof cap. They have OSHA warning labels and come in a range of sizes. Formalin is a fixative for preparing histological specimens in several specialty areas.
Other popular options include plastic containers with a screw cap or peti-vials. These containers are filled with 3.5 mL of 10% neutral buffered formalin and feature a leakproof screw cap that is easily opened by hand or gloves. Given that they are constructed of transparent polypropylene, which is easily cleaned with soap and water, this sort of container is simple to maintain. They are also autoclavable and come with a pressure-sensitive lid that prevents leaks. If your laboratory requires prefilled formalin containers, it is essential to keep these items in good condition and ensure they are not damaged or misplaced. They must be kept in a cool, dry place. Well-ventilated area and kept tightly closed until they are needed for use. They should not be placed in contact with oxidizers, reducing agents, metals, or acids, as they could cause damage to the containers or the samples they hold. Empty Formalin ContainersClinical specimen containers are an essential item in most healthcare departments. Various sizes are available, ranging from 20ml pots to 10L containers for particularly big specimens. and are prefilled with formalin so that samples can be quickly processed and sent to the laboratory. While the use of formalin in a specimen container is an excellent idea, there are some drawbacks. These include: When using an empty formalin specimen container, it is important to ensure that the lids are screwed on tightly and that labels adhere properly. This will prevent leaks that could render the labels illegible. Another issue with empty formalin containers is that they cannot be used in the sterile field. This is because formalin cannot be sterilized as a tissue fixative. This may cause problems when using core biopsy needles or biopsy forceps. Using a separate bottle for specimens retrieved from the sterile field is best. This way, the liquid will not come into contact with the device, which may be reused for subsequent retrievals of the sample. Additionally, it is crucial to provide that the requisitions contain the correct identifying information and that they are complete and concordant with the sample bottles included in the requisition. This will help to avoid confusion when a courier collects the specimen. Finally, it is vital to store empty containers in a cool, dry place until the courier picks them up. This will protect the specimens and keep them from spoiling. The disadvantage of these containers is that they are prone to breakage when they are dropped or bumped, so they should be stored carefully. Some companies provide stackable plastic containers with caps, particularly suitable for this purpose. When disposing of empty formalin containers, finding a local hazardous waste treatment plant is a good idea. This will allow you to dispose of the containers and any leftover embalming fluids or liquid biohazards in a manner that is safe for both human and animal health. The SecurBiop(r) closed system histology container is an ideal solution for eliminating the risk of exposure to formalin. It is designed with a membrane and an 'O-ring,' which prevents the dispersion of both vapors and liquid from the specimen container. Formalin automatically flows from the cap into the container only when closed during the procedure. Prefilled TissuePrefilled tissue specimen containers are a common solution for clinical laboratories. They are filled with a neutral buffered formalin fixative and come in various sizes. They can be used for various applications, including fixation and storage of skin curetting, endoscopic biopsies, and fine needle cores. These containers can also store sample samples in upright chest freezers or vapor phase Dewar flasks. The container and lid are high-density polyethylene, offering excellent sample retention for long-term storage at -196degC. In addition, the containers are sterile and leakproof and have Widemouth openings that make loading and handling easier. They are also reusable and can be labeled with patient identifiers. The containers are half-filled with a 10% neutral buffered formalin fixative, penetrating quickly and fixing slowly to optimize histological results. The containers come in various sizes and are suitable for pathologists, radiographers, and microbiologists. When using these containers, it is important to follow laboratory protocols for collecting and transporting tissue samples. It is also essential to ensure that the requisition forms and containers are correctly labeled with patient identifiers. It is important to maintain a proper biosafety environment while transporting specimens by ensuring that the requisition form is placed in a zipped PRW biohazard transport bag. It is also necessary to seal the container(s) and requisition sheet with a tight seal and to store them in a sterile storage box until courier pickup. Although many nurses and consultants use the liquid in these containers to help retrieve core biopsy needles or other devices, this is not recommended because it brings the formalin into direct contact with the device. This practice can increase the risk of contact with formalin, which can be carcinogenic. Another disadvantage of prefilled histology containers is that they cannot be sterilized. This means they cannot be used to process tissue samples in the sterile field. Epredia's BiopSafe histology containers provide a safer alternative, as they are sterilized through CSSD and can remain in the sterile field while they are being used to process tissue samples. Empty Tissue Specimen ContainersContainers are available in various sizes and can be prefilled with formalin or RNAlater. They are used to store, transport and freeze tissue specimens for analysis. Unlike prefilled forms, empty tissue specimen containers do not contain any liquid form of fixative but can still be contaminated with fluids that can cause the container to become degraded. These types of containers should be disposed of properly to avoid the risk of cross-contamination. The lid should be firmly fitted to prevent leakage of fluid. Labels on the container should be clearly written with the patient name and number, site of study, and specimen type (i.e., nasopharyngeal swab or brushing slide). Many laboratories use empty containers to transport and store their most commonly used tissue specimens. They are convenient and cost-effective, allowing the user to keep an accurate inventory of all histological samples in a single location. These containers are also useful for storing and resealing brushing slides and other equipment, which can be used during processing. The caps on these containers are usually made of polypropylene material and can be screwed tightly to eliminate leakage of fixative, preventing stains from appearing outside the container. Some of these containers have a patented "O-Ring" cap, which provides a tight seal that eliminates most formalin leakage and evaporation. They can be purchased in various sizes and are especially well-suited for use with large sections of tissue. In addition to using these containers for transport and storage, they can be useful in helping histotechnicians perform grossing of tissue sections. Using these prefilled containers can reduce the time and expense of grossing and ensure that tissue is protected during transport to the laboratory. To minimize the risk of bacterial contamination during processing, it is recommended that all grossing containers be prefilled with a non-precipitating fixative, such as Scigen Neutralex 4047, which eliminates the need for routine, warm water flushes. This can save valuable time and money while improving the quality of grossing.
