Frequently Asked Questions
What types of samples are suitable for wire sampling bags?
SDLABIO’s wire sterilized bags are suitable for solid, powder, semi-fluid and other samples, and are widely used in food, soil, medicinal materials, raw material sampling and other scenarios.
How to seal the wire sterile bags? Is the seal firm?
The bag mouth is integrated with aluminum wire, which can be sealed by manual folding, suitable for field sites or environments where heat sealing tools are not required.
Are biohazard bags leakproof? Can they hold liquid or wet waste?
The bag is thick and leakproof with a heat-sealed bottom seal, which is suitable for wet biological waste, but it is not recommended to hold large amounts of liquid directly.
Are the laboratory homogenizer bags compatible with a slap-type homogenizer?
Yes. The standard blender bags with filters width is 19 cm, suitable for all types of slap-type homogenizers.
Do the biohazard specimen transport bags support cold chain transportation? Is the bag transparent?
The bag is made of transparent PE material and supports use in a refrigerated environment, which is convenient for visual inspection.
Are there any gas permeation or adsorption issues with the FEP gas sampling bag?
FEP film hardly adsorbs most organic gases and has extremely low permeability, making it suitable for high-demand trace gas analysis.
What is the difference between FEP gas sampling bags and Tedlar gas sampling bags?
FEP gas sample collection bags have stronger chemical resistance and lower adsorption, and are suitable for corrosive gas and trace component analysis; while Tedlar bags are more cost-effective and suitable for conventional air and VOCs sampling. If the sample purity requirements are extremely high, it is recommended to use FEP.
What types of gases are multi layer foil gas sampling bags suitable for?
It is mainly suitable for sampling volatile or highly photosensitive components such as VOCs, organic solvent gases, hydrogen sulfide, ammonia, etc., and is widely used in monitoring odorous gases and emission sources.
Can aluminum multi foil gas sampling bags be reused?
In principle, it is disposable. If it collects non-corrosive gases and does not contaminate the inner wall, it can be reused after limited cleaning and drying.
How to use gas sampling bag？
- Check the status of the sampling bag
- Connect the sampling equipment
- Inflation sampling
- Close the valve
- Sample storage and transportation
How to store biohazard specimen bags to ensure performance?
Please store in a cool and dry place, away from direct sunlight, high temperature or humidity. It is recommended to use within the shelf life (usually 2 years) to avoid aging of the bag and affecting the sealing effect.
Can sterile sample collection bags be used repeatedly? Will the sealing performance deteriorate?
Please store in a cool and dry place, away from direct sunlight, high temperature or humidity. It is recommended to use sterile sampling bags within the shelf life (usually 2 years) to avoid aging of the bag and affecting the sealing effect.
What are the uses of different colored autoclavable biohazard waste bags?
- Yellow biohazard bags are mainly used to hold infectious medical waste, such as dressings, syringes, gloves, masks, etc. contaminated by blood, body fluids, and secretions. They are commonly found in fever clinics, laboratories, ICUs, and other departments, and have a high risk of infection.
- Red biohazard bags are usually used to collect pathological waste, such as human or animal tissues, organs, placentas, etc., which mainly come from operating rooms and pathology departments and are special medical waste with greater biological hazards.
- Blue bag medical waste is mostly used to load uncontaminated recyclable medical waste or pharmaceutical waste, such as expired drug packaging and unused chemical reagent bottles. The specific use may vary depending on regional regulations.
What is the sterilization method for biohazard garbage bags?
Some models provide gamma ray sterilization versions, which are suitable for sterile experimental areas or high-risk pathogen packaging areas. The sterilization batch and logo will be indicated on the product packaging, and a sterilization report or compliance statement can be provided.
