The small plastic sample bags are a great way to handle and store samples. They are sterilized, won't break, and cost less than other containers like glass bottles or beakers.
These single-use sterile service bags are made of heavy, transparent polyethylene. They have a write-on strip for recording the number of soil increments collected.
The small sample bags can be used to transport liquids to a laboratory. The bags are strong, sterile, and leak-proof.
These sample bags are ideal for storing milk, soil, feed, or other types of samples. They are reusable, easy to handle and take up only a small amount of space.
They are available in 4- and 18-oz sizes. They are made from a copolymer of polyethylene and feature puncture-proof aluminum wire tabs.
During the sampling process, the bag can be opened by pulling on the two grip tabs located on each end of the closure. After the sample is inside, simply flip or fold the bag three times and bend the wires together to close it.
The bags are sterilized and have a special FDA-grade silicone seal. The silicone seal provides superior sampling action and prevents the bag from dripping between uses.
A sterile small ziplock sample bags is used for microbiology and cell culture series. This small sample bag is made of heavy, transparent polyethylene with a write-on strip that eliminates the need for tapes or labels.
SureSeal(tm) bags are gamma sterilized after gas exposure to ensure a toxic residue-free interior surface, resulting in a completely sterile environment in the sampling bag. To get samples, just tear off the strip above the wire closure and pull on the two grip tabs on the outside of the bag to open the mouth.
These bags are sterile, RNase-free, and non-pyrogenic, meeting USDA, EPA, and FDA standards. A PVC tab around the stainless steel wire reduces the possibility of puncture or exposure and has a white printed area for long-lasting markings.
This product has been approved for aseptic water collection by many states and the EPA. It also features a convenient write-on strip and markings for 100 ml and 300 ml measurements. It is strong, transparent, and folds flat for easy storage and transport.
Culturing of microorganisms remains the mainstay of laboratory testing for infectious diseases. For this reason, special attention must be paid to the collection, transport, and processing of these specimens.
To keep contamination of media and cultures to a minimum, use serological pipettes for the transfer of liquids into sterile test tubes. These pipettes have a plastic tip, a barrel tip holder, and a thumb wheel for changing the volumeter setting.
A sterile field is created by an updraft of the Bunsen burner flame, shown in Figure 1. All manipulations must be done in this sterile area to keep the culture media and flasks from getting dirty from touch or hands that might touch the rim.
For example, a sterile 125-ml flask must first be filled with 25 ml of LB using a serological pipette (see Figure 7). Next, E. coli cells must be inoculated into the LB broth. A pure bacterial culture will display uniform fine turbidity, while a contaminated culture may not (see Figure 8A). These differences in growth characteristics are caused by the presence of airborne microorganisms. Another type of product on the market is the lab sample bags.
Small plastic sample bags are used in the sampling process, for example, when a sample has to be analyzed immediately after collection. These are often made of heavy, transparent polyethylene.
Biological reagents, such as those for blood fractionation and cell isolation, nucleic acid extraction, and DNA and RNA PCR, are commonly stored in these bags. They are made to be sterile, stay away from people's bodies, and meet the requirements of official sterility paperwork.
In some cases, a sterile sampling bag is not necessary, and sample processing can be carried out on-site. This is usually the case for vapor-phase samples that can be analyzed within a short time after collection.
A subdivider can be used to subdivide the sample longitudinally into two approximately equal parts. It is important to ensure the thickener is clean prior to dividing the sample and to discard any of the alternate portions before starting a new riffling stage. This method may produce some dust, but the amount depends on the nature of the sample and the operatoru2019s skill.
