Product Description

Steam autoclaves leave moisture behind. That moisture rusts metal instruments and shortens their working life. UV cabinets only sterilize what the light can see — the hinges, the crevices, and the undersides of tools stay contaminated. Chemical soaks leave residue that has to be rinsed off before the tool touches a client.

The High-Temperature Sterilization Cup with Quartz Sand was built to solve all three problems at once. It uses natural quartz sand as a dry heat transfer medium — no water, no UV bulbs, no chemical solutions. Instruments are buried in the sand, heated evenly to a precise temperature, and pulled out completely dry, ready to use.

This is dry heat sterilization done properly: uniform, chemical-free, and safe for a wider range of materials than any steam-based system.

Key Advantages

01

Quartz Sand as the Medium

Natural quartz sand conducts heat far better than air and holds it longer than water. Instruments buried in the sand receive even heat from every direction — no hot spots, no cold zones, no line-of-sight limits.
02

Zero Moisture, Zero Rust

Because there's no water in the process, metal instruments come out dry and oxidation-free. Scissors, forceps, and needle holders keep their edge and finish far longer than they would after repeated steam cycles.
03

Precision You Can Set

Adjustable from 80°C to 200°C in 1°C increments. Delicate silicone items get a gentle 100°C cycle, while stainless instruments can run at 180°C for full spore elimination — all on the same machine.
04

Compact Enough to Travel

At 1.8 kg and 18 × 15 cm, the cup fits on any counter or in a mobile kit. Silent operation under 40 dB means it can run in a client-facing room without disrupting the atmosphere.

Temperature Guide by Material

Different materials tolerate different temperatures. Use this table to set the right cycle for your load — always choose the lowest safe temperature among all items in the cup.

Material Type	Recommended	Maximum Safe
Silicone (pacifiers, teething rings, tubing)	100–120°C	180°C
Glass (bottles, jars, slides)	120–140°C	200°C+
Stainless steel instruments	160–180°C	200°C+
Heat-resistant plastics (PP, PTFE)	100–120°C	130°C (check label)
Quartz / ceramic tools	140–160°C	200°C+

Mixed loads: Always set the temperature to the lowest heat tolerance among all items in the cup. If you load silicone nipples (max 120°C) alongside steel scissors, run the cycle at 100–120°C to protect the silicone.

Installation and Safety

Place on a level, heat-resistant surface — away from flammable materials.
Allow 15 cm clearance on all sides for proper ventilation.
Do not overfill — leave space for quartz sand circulation.
Always dry instruments before loading — moisture can cause sand clumping.
Use the child lock when not in use to prevent accidental operation.

Frequently Asked Questions

Q: How does the cup work, and why quartz sand instead of water or air?

Natural quartz sand acts as both a heat transfer and heat retention medium. Air is a poor conductor — it heats unevenly and loses temperature quickly. Water conducts well but leaves moisture behind, which rusts metal. Quartz sand conducts heat efficiently, holds it steadily, and leaves instruments completely dry. The sand also physically stabilizes instruments in place, preventing contact with the hot chamber walls.

Q: Can it sterilize both metal instruments and silicone baby products?

Yes — the key is setting the correct temperature for the load. Metal instruments can run at 160–180°C for full spore elimination, while silicone items should stay at 100–120°C to preserve flexibility. For mixed loads, always set the temperature to the lowest tolerance among all items in the cup.

Q: How do I clean and maintain the cup?

After each use, let the cup cool, pour out the quartz sand into a clean container, and wipe the stainless steel interior with a dry cloth. Weekly, spread the sand on a baking sheet and heat at 120°C for 30 minutes to evaporate absorbed moisture, then sift out any debris. Monthly, inspect the heating element and verify temperature calibration with a separate thermometer. Replace the quartz sand every 6–12 months, or sooner if it appears oily, clumped, or strongly discolored.

Q: How often does the quartz sand need to be replaced?

Every 6–12 months under normal use. Replace immediately if the sand appears oily, clumped, or strongly discolored, or if you notice uneven heating or prolonged cycle times. Replacement sand is available directly from Ruina Optoelectronic in 1kg refill packs.

Q: Is it safe to use around clients?

Yes. The unit runs under 40 dB — quieter than a normal conversation — and has no open flame, no steam, and no chemical fumes. The child lock prevents accidental operation, and overheat protection plus dry-run prevention keep the unit safe during unattended cycles.

Q: What certifications and warranty does it carry?

The unit is CE, RoHS, and FDA registered. We provide a 2-year limited warranty covering manufacturing defects. Our after-sales team also provides technical support and troubleshooting for international customers.

Supplier Advantages

When you source from Ruina Optoelectronic, you are not just buying a sterilization cup — you are gaining a manufacturing partner who understands the regulatory, logistical, and branding pressures of your market. Here is what that partnership looks like in practice.

Flexible Order Scales, Consistent Quality

Our 1,500-square-meter production facility in Shenzhen is set up to handle everything from sample runs to full container loads without compromising on consistency. Every batch is traceable by lot number, so you can verify quality long after delivery. Our 468-square-meter office space houses sales, design, and support teams under one roof, which means faster answers and fewer handoffs when you need something customized.

Certification and Compliance Support

We help you clear regulatory hurdles before they become problems. Our products are tested and certified for the markets we serve, and we provide the documentation you need for customs and compliance:

CE & ROHS · EU

For private-label and distribution partners, this translates into fewer delays at the border and faster time to shelf. View our full certification documentation →

OEM and ODM That Actually Fits Your Brand

We do not treat customization as an afterthought. Whether you need a different chamber size, a custom color, your logo on the housing, or a completely new specification, our OEM and ODM services are built around your requirements. That includes branded packaging, presentation boxes, and private labeling — all managed through the same production team that builds the standard units.

Logistics Built for Export

Our Shenzhen location puts us within a 30-minute drive of both Shenzhen North Station and Shenzhen Bao'an International Airport (Terminal 3). That proximity gives us fast access to raw materials and efficient outbound shipping, so your order moves from production line to port without unnecessary delays.

Support That Outlasts the Sale

We stock replacement quartz sand, filters, and spare parts for the long term. If something needs troubleshooting, our after-sales team provides technical support and documentation for international customers.
