Muffle furnace - tube furnace - vacuum furnace and vertical autoclave

SH Scientific has been a leading manufacturer of various types of furnaces since 1982 for the industries needing material testing and treatment, annealing, ashing, sintering, biochar processing from agricultural wastes and etc.

We provide various temperature coverage (1050°C, 1200°C, 1500°C, 1700°C, 1800°C) matching your budget and application as well as various sizes. Not to mention small scale general application but also we perform large scale custom project such as rotary kiln.

Does your lab need sterilization for glassware, tools and media? Our vertical autoclave will be your fastest solution with greater volume. 

Muffle Furnace

SH Scientific muffle furnaces have chamber capacities from 3L to 36L 
with maximum temperatures ranging from 1050°C to 1800°C.

Muffle furnaces are ideal for ashing samples, heat-treating applications and material testing and research. These days the use of furnaces are more rapidly growing throughout the advanced industries such as secondary battery, graphene battery, polymer composite, treatment of titanium

Good news! Are you looking for vacuum muffle furnace for carbon-free atmosphere for metal injection molding, metallization and sintering? CVD (CHEMICAL VAPOR DEPOSITION) FOR GRAPHENE development and production? SH Scientific vacuum muffle furnace is the solution providing a precisely defined atmosphere with the highest possible purity.

Our muffle furnaces specification includes (but not limited to):

  • Flap door or swing door
  • Heating from 3 sides or 4 sides with excellent temperature uniformity (+/-2.5%)
  • Heating from 2 sides and vertical SiC rod preventing warping (1500°C only)
  • Heating from 2 sides and vertical MoSi2 rod preventing warping (1700°C and 1800°C only)
  • Excellent outgassing thanks to the exhaust air outlet on the head of chamber, i.e plastic polymer
  • Single housing or double housing

Vacuum Furnace

Do you have concerns if your materials would be oxidized during the heat treatment?
Do you want to carry out your test, process and production in fully controlled oxygen-free environment? CVD (CHEMICAL VAPOR DEPOSITION) for GRAPHENE development and production?
And you don’t know how?

Your choice is vacuum furnace!

General muffle furnace can not create fully saturated inert gas environment around the corners of the chamber due to the non-crossing streamlines phenomenon.
Tube furnace with vacuum applied can be a good selection for saturating your tube with inert gases but what if your sample is big?

Vacuum muffle furnace (in short, vacuum furnace) overcomes the trouble of imperfect saturation as well as the limit of sample sizes.
You can create multiple atmospheric environment according to your plan (burning and ashing in air, purging air and pulling vacuum, flowing inert gas and sintering).

SH Scientific is proud of this innovation of MGV (1200℃) and MHV (1500℃) vacuum furnace with various chamber sizes for your successful research and production with affordable prices.

Vertical Autoclave

Autoclaves are widely used in various labs such as research, medical and therapeutic labs and manufacturing facilities where they need to sterilize glassware, tools and media. Compared with horizontal style benchtop autoclaves, SH Scientific vertical style autoclaves boast of incomparable yield thanks to large scale chamber, easy loading and unloading and quickest sterilization time.

SH-AC-60M (60L) SH-AC-100M (100L) and SH-AC-150M (150L) Vertical Autoclave

Sterilizing lab supplies and tools by subjecting them to pressurized steam under 15psi at 121℃ (250°F ) for certain length of time per the size of the load and materials. Are you mushroom farmer? Sterilizing substrates with our autoclaves will simplify and streamline your process!
