For fermentation experiments, aseptic sampling is a key step to ensure experimental accuracy and product safety, and its importance is self-evident. However, the complicated and risky sampling process of traditional stainless steel fermenters has always been a problem for research and industry. HOLVES has responded to this problem by introducing a sterile sampling device that simplifies the sampling process and aims to provide a simpler, more efficient and sterile sampling solution.

HOLVES aseptic sampling device consists of two core components - a five-hole sampler and a disposable aseptic sampling bag, is a sampling system designed specifically for biotechnology processes, which adopts an innovative closed design, the combination of the two for the sample and the sampling point to build an impenetrable barrier between the sample to avoid cross-contamination, effectively, protect the production process aseptic environment. It protects the sterile environment of the production process.
 

Five-hole sample

1. Porous design: The five-hole sampler has five independent sampling holes, allowing the user to carry out multiple sampling without the need to repeat the installation, greatly improving the sampling efficiency; anti-touch design, so that the sampling operation is faster and safer.
2. Material Selection: Stainless steel and aluminum alloy are used to ensure the durability and corrosion resistance of the equipment while maintaining lightness.
 
Disposable sterile sampling bag

1. Sterility: the sampling bag adopts special materials and sterilization process to ensure the sterility of the contents, prevent microbial contamination and ensure good chemical stability and sealing. The sampling bag is designed with an easy-to-operate interface, making the sampling process faster and more convenient.
2. Versatility: Sampling bags of different volume, such as 50mL, 100mL, 250mL, 500mL and 1L, are provided to meet the sampling needs of different sizes.
 

1. High standard sterility guarantee: advanced sealing technology and aseptic processing procedures ensure the purity and integrity of the samples.
2. Efficient operation process: simplify the sampling steps, no need for complex training, pre-assembly, pre-sterilization design, ready to disassemble and use, quickly complete the sampling work, save time and effort, improve work efficiency.
3. Compatibility and versatility: suitable for a variety of specifications and types of stainless steel fermenters, to achieve seamless and perfect fit.
 

1. Sampling needle installation: put the sampling needle of the sterile sampling bag into the slide rail of the sampling base and fix it with screws.

2. Installation of sampling device: Install the sampling device to the fermenter and make sure it is firmly connected.

3. Sampling operation: Press the sampling needle, and the liquid flows into the sterile sampling bag.

4. Separate the sampling bag: Using pliers to clamp the metal ring, cut and seal the sampling bag.

5. Pipetting operation: Use a syringe to extract the target volume of material solution to complete aseptic sampling.

HOLVES offers a wide range of aseptic sampling devices with capacities from 50mL to 1L to meet the needs of different users. Each device is equipped with appropriate tubing and sterile sampling bags to ensure the sterility and convenience of the sampling process.
