- Questions
Lorderan vertical high-pressure steam sterilizer with a traditional bolt-down lid and an all-SUS 304 stainless steel build. Set the temperature and the time, close the lid, and the cycle runs on its own: it heats, holds, exhausts automatically, then beeps and switches off. Four sizes from 35 to 150 L, with stackable baskets that make loading and unloading easy.
We know trust has to be earned back.
Some of you told us that an earlier sterilizer did not hold up the way it should have. We heard every one of those messages, and we are not going to pretend otherwise.
A sterilizer is a machine you trust with your cultures, your spawn and your working day. So we went back to the parts that matter most: the heating elements, the lid seal, the sensors and the controls, and to how each unit is checked before it leaves us. We would rather show you than ask for your word. Here is exactly what we check.
Inside the vessel
Water sits in the bottom of the chamber over two heating elements. Steam rises through two stacked stainless baskets, a flexible PT-100 probe reads the temperature at the load, and the bolt-down lid seals the vessel to 33 psi.
Specifications
Models 35B, 50B, 100B and 150B. The 35L, 50L and 100L are offered in 110 V and 220 V versions; the 150L is 220 V only.

Choose a size
Same pressure, temperature range, controls and protection on every model. They differ in chamber size, baskets and heating power. Drawn to the same scale; the dashed outline is the inner chamber.
One 150L = five 30-quart cookers
Sterilize grain spawn in one cycle, with no stove to watch.
- 158 qt150L chamber
- ≈25 minto pressure
- Pasteurizeadjustable temperature for substrate
One button, one full cycle
Set the temperature and the time. The controller heats, holds, exhausts, then beeps and switches itself off. Fewer settings mean fewer things to go wrong.
Automatic exhaust
Pressure is released when the timer ends. The quick choice for dry goods, glassware, instruments and grain spawn bags.
Non-vent mode
The vessel stays sealed and pressure falls slowly. Use it for liquids and media to prevent boil-over. One button switches modes.
What we check on every unit
Each sterilizer passes this checklist before it is packed. If one item fails, the unit does not ship.
When it arrives, put a standard biological or chemical indicator in your first load and confirm the result for yourself.
Protection at every layer
The unit watches temperature, pressure and water level throughout the cycle. If anything goes outside its limit, it protects itself and tells you. Each of the two heating elements has its own audible and visual alarm, so a fault points straight to the part to replace.
- Over-temperature protection
- Over-pressure self-venting
- Safety valve on the lid
- Low water level protection
- Dry-run protection
- Leakage breaker
- Alarm for each heating element
- Auto shut-off with beep
110 V or 220 V?
The same power drawn at half the voltage needs twice the current. Up to 100L, both supplies are offered. At 6 kW, the 150L would need about 50 A at 120 V, so it is supplied for 220–240 V only.
Why is the 150L 220 V only?
Circuit and breaker limits
Standard residential and light laboratory circuits in North America are typically protected by 15–20 A breakers, and codes such as the NEC derate breakers to 80% for continuous loads.
Wiring and material cost
Carrying 50 A safely needs much thicker wire, typically 4 or 6 AWG depending on conditions. That makes a 120 V install impractical and costly.
The lab standard
208 V or 220 V single-phase power at around 30 A is the common laboratory supply, and it runs the 150L comfortably.
Honest answers
The questions we hear most from people who have been let down before.
What if my unit has a problem?
Contact us with your order number and a short description or video. An engineer will work through it with you. Major defects under the 1-year warranty are covered by a full refund or replacement.
Can I get spare parts?
Yes. Heating elements, gaskets, sensors and valves are designed to be easy to replace, and each heating element has its own alarm so you know which part to change.
What if it is not right for me?
Return most new, unopened items within 30 days for your money back.
Will there be surprise costs on delivery?
No. Shipping is free and delivered duty paid (DDP), so there are no import charges on arrival.
