Which sample formats can be used?

Optional racks can support vials, blood bags, canes and straws. Please advise the sample format, quantity and dimensions for correct rack selection.

What information is needed for a quotation?

Please provide sample type, container format, quantity per run, target freezing programme, voltage/frequency, destination country or port, and any certification or validation requirement.

Can LCX-17 be used for GMP or clinical workflows?

It can support controlled freezing workflows, but compliance depends on the complete user process, documentation, facility controls and validation. The customer is responsible for confirming regulatory suitability for the intended use.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company whose scope includes gas, gas separation and purification equipment, machinery, installation, technical services, and import/export activities. It reports more than ten years of gas design and R&D experience, broad customization and ODM/OEM capabilities, available SDK support, and documented procedures for supplier service assessment, corrective actions, and customer complaints. Production information states annual outputs of 300 nitrogen generator sets, 350 oxygen generator sets, and 150 liquid nitrogen generator sets, with finished-product inspection instructions followed uniformly. ISO 9001:2015 certification is reported. Financial records are indicated for 2021–2023, but no financial results are provided. Overseas support appears limited because no overseas showroom, agent, branch, or offline trade-show participation is reported. No specific customer cases are disclosed.

CertificationsThe supplier reports holding an ISO 9001:2015 certificate and also reports uniformly followed instructions for finished-product inspection. The available evidence supports quality-management certification, although no other certifications are identified.

After-Sales capabilityThe supplier reports clear procedures and followed records for handling customer complaints, corrective and preventive actions, and service-capability assessment. It also states that its technical team provides pre-sale, sales, and after-sales technical support, including installation guidance and training; however, it reports no overseas agents, branches, showroom, or overseas-service countries.

R&D capabilityThe supplier reports more than ten years of gas design and R&D experience, a professional technical team, new products during the past year, ODM services, OEM services for well-known brands, and an available SDK. These statements provide explicit evidence of established product-development and technical-support capability.

Production capacityReported annual production output is 300 nitrogen generator sets, 350 oxygen generator sets, and 150 liquid nitrogen generator sets. The supplier also reports a one-month off-peak lead time, finished-product inspection instructions that are uniformly followed, and 11–20 quality-control staff, supporting a documented production and quality-control operation.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, providing direct evidence of broad customization and original-design support.

Product Q&A

Q:What is a controlled-rate freezer used for?

It cools biological samples according to a programmed temperature profile before transfer to cryogenic storage. Controlled cooling can improve repeatability compared with uncontrolled freezing.

Q:Does LCX-17 store samples long term?

No. It is a programmable freezing unit. After the freezing run, samples should be transferred to a separate cryogenic storage system according to the laboratory SOP.

Q:Does the unit need an external LN2 vessel?

Yes. A compatible self-pressurized liquid nitrogen vessel is recommended to provide stable LN2 supply pressure.

Q:Can I create my own freezing programme?

Yes. The controller supports default programmes and user-defined programmes. The user must validate the selected programme for the sample type and intended process.

Q:What data can be recorded?

The system records the temperature curve of each freezing cycle. Chamber and sample temperatures can be monitored; data may be exported via USB.
