A practical FAQ for buyers choosing among the CA-1-300, ASTF-1, and LCA-1-300. It explains portable collection, continuous sampling, airflow, run time, and the difference between collecting a sample for later analysis and using an integrated PCR workflow.
The right instrument depends on the sampling duration, air volume, sample analysis method, and working environment. SUZHOU CHANGHE BIOTECH CO., LTD lists the CA-1-300, ASTF-1, and LCA-1-300 for different collection and detection workflows. If portable ambient-air collection is your starting point, review the CA-1-300 product page.
The CA-1-300 collects bioaerosols from ambient air using wet-cyclone operation. Listed applications include animal husbandry, pharmaceutical production, food manufacturing, laboratories, hospitals, exhibition venues, shopping malls, restaurants, offices, rail transit, classrooms, and stadiums. The collected sample is compatible with qPCR or sequencing analysis.
It fits teams that need to move a unit between rooms or sites. The sampler is described as lightweight and portable, with a built-in battery and a user interface designed for easier operation.
The CA-1-300 has two listed airflow settings: 150 L/min at low flow and 300 L/min at high flow. Its running time can be set from 1 to 15 minutes, and it collects particles at or above 0.8 μm.
For a room survey, decide whether low or high flow suits the sampling plan and select a running time within that range. Include the target room, number of locations, desired flow setting, and sampling duration when requesting a quotation.
The LCA-1-300 is intended for continuous collection. It uses wet-cyclone technology to capture airborne components into a sampling solution and automatically replenishes the solution. Its listed continuous operation is up to 48 hours, with low and high airflow settings of 150 L/min and 300 L/min.
This model suits a plan requiring extended operation in locations such as hospitals, laboratories, production areas, public venues, or transit spaces. Before ordering, send the intended monitoring duration, installation location, power arrangement, and sampling schedule so the configuration can be matched to the worksite.
The CA-1-300 is described as a collection device whose sample is compatible with qPCR or sequencing analysis. The ASTF-1 is a different product: it combines wet-cyclone air collection with automated nucleic-acid extraction and PCR detection using four fluorescence channels, FAM, CY5, ROX, and HEX.
Choose the CA-1-300 when the requirement is portable collection for later analysis. Choose the ASTF-1 when the workflow calls for integrated collection, extraction, and PCR detection. The ASTF-1 has a listed flow rate above 300 L/min and a sampling time of 5 to 15 minutes.
Identify the intended model or workflow, application site, airflow requirement, sampling duration, particle range of interest, downstream analysis method, and required quantity. For the CA-1-300, the relevant operating choices include 150 L/min or 300 L/min airflow and a 1 to 15 minute running time. For extended monitoring, state whether the LCA-1-300's continuous function is required. For integrated PCR work, describe the ASTF-1 workflow requirement.
Also include the destination country, delivery location, and site constraints that affect placement or power. Send these details with the number of units and intended analysis method so SUZHOU CHANGHE BIOTECH CO., LTD can respond to the correct configuration.
