SpongesCollect™ Cellulose Buffered Peptone Water, 10 mL được thiết kế để lấy mẫu vi sinh vật từ các bề mặt trong môi trường chế biến thực phẩm, y tế và dược phẩm. Mục đích chính của sản phẩm là hỗ trợ việc thu thập mẫu vi sinh vật từ các bề mặt lớn, dễ tiếp cận, các khu vực xung quanh trong các cơ sở sản xuất thực phẩm. Buffered Peptone Water là môi trường tiền tăng sinh không chọn lọc cho các loài Salmonella trong thực phẩm, giúp duy trì sự sống và ổn định của vi sinh vật trong suốt quá trình vận chuyển và phân tích.
SpongesCollect™ Cellulose Buffered Peptone Water, 10 mL sử dụng miếng bọt biển Cellulose không chứa biocide kết hợp với 10 mL môi trường Buffered Peptone Water để thu thập vi sinh vật từ bề mặt. Buffered Peptone Water chứa các thành phần chính như peptone, sodium chloride (NaCl) và phosphate buffer. Peptone cung cấp nguồn nitơ và amino acid thiết yếu cho sự phát triển của vi khuẩn, giúp phục hồi các vi sinh vật bị suy yếu trong quá trình chế biến thực phẩm. Sodium chloride (NaCl) duy trì áp suất thẩm thấu ổn định, tạo điều kiện thuận lợi cho vi sinh vật trong môi trường, trong khi phosphate buffer giúp giữ pH ổn định, đảm bảo môi trường thích hợp cho vi khuẩn hồi phục và phát triển trước khi chuyển sang môi trường chọn lọc. Quá trình này giúp bảo vệ vi sinh vật trong suốt quá trình vận chuyển và phân tích mà không làm thay đổi đặc tính của mẫu.
- Inspect the SpongesCollect™ product to ensure there is no damage or contamination during storage.
- Write sample information on the provided label attached to the product packaging.
- Tear the bag along the pre-marked perforated line.
- Push the sponge near the edge of the bag so that part of the sponge is exposed for easy handling. Hold the sponge from the outside of the bag and carefully remove it directly by hand, making sure not to touch the inside surface of the bag to avoid contamination.
- Immerse the sponge into a sterile buffer/culture medium as required (if necessary).
- Rub the SpongesCollect™ sponge on the area to be sampled.
- After sampling, return the sponge to the bag. Ensure the sponge does not fall out and avoid direct contact with the outer surface of the packaging.
- Use the provided tie to seal the SpongesCollect™ bag by rolling the top of the bag and tightly twisting the tie inside the bag.
- The sample must be sent to the laboratory as soon as possible to prevent changes in microbial characteristics. The transportation process should comply with sample storage regulations.
