Fused Quartz Tubing Grades
As a major distributor within Europe Multi-Lab is dedicated to holding
large stocks of high purity Fused Quartz Tubing from the world’s largest
manufacturers. These stock sizes range from 3 mm O/D through to 580 mm
O/D.Lengths up to 3,500 mm are available. All the company’s materials have high
transmittance, purity and temperature with low hydroxyl content. Multi- lab
offers three basic types of quartz glass types, each designed to fulfil specific
- Clear fused quartz tubing (OH <.00ppm).
Utilized mainly in high
temperature and high performance lamps such as quartz halogen, mercury,
ultra-violet (UV) lamps, semiconductor quartz ware, wave-guide handles
thermocouples and high temperature products.
- Clear Fused quartz tubing OH <1.00ppm)
Within the high specification
of this material the extremely low hydroxyl level makes it the ideal material
for producing metal halide lamp envelopes and other applications requiring
extremely low hydroxyl content.
- Clear fused quartz tubing doped with titanium.
This material is commonly
called 'germicidal' or 'ozone free' quartz glass. It is produced to transmit
UV-A and UV-B while blocking the deep high wavelengths. This makes it a suitable
material for many disinfecting applications and various other UV treatment
Quartz Transparent Rods
Multi-Lab has a range of drawn quartz rod. The clear fused quartz rod of the
company has minimal air lines and inclusions, and excellent dimensional
stability. This material is natural quartz pulled from a Single-step furnace,
the rod is directly drawn in a continuous electrical-fusion process that covers
an outer diameter range from 1.00 mm to 90.00 mm. These rods are produced in
non-semiconductor and semiconductor grades. Above this size the company
'core-drills' ingot material. This can be natural or synthetic.
Sizes range up to 550 mm diameter with various lengths being catered for,
depending on customers' requirements.
Quartz Tubes & Components
A complete range of synthetic quartz is available from Multi-Lab. Ranging
from rod form to boules, these can be sliced, ground and polished. This material
is an ultra-pure synthetic fused silica for use where optical transmission in
the deep ultra-violet spectrum is required or where an ultra-low level of
impurities is crucial. It is ideal for all but the most rigorous optical
applications. This material is utilized also for a range of UV lamp applications
including water purification, ozone generation, paint and ink curing, and
Opaque Quartz Glass
With opaque material it is the material’s microporosity that gives this
material its specific properties - superior to other materials on the market.
Excellent thermal shielding, high density, excellent thermal shielding, blocks
IR transmission, smooth surface finish, and cost efficient is the way the
material is machined. Opaque quartz glass material can be applied at high temperatures in
aggressive environments with standing temperatures up to 1100°C.
Quartz Polished Discs & Profiles
Full machining, grinding and polishing of quartz are catered for. The normal
tolerances are ± 0.2 mm on diameter and ± 0.2 mm on thickness and flatness, 1
wavelength per cm, tighter tolerances can be achieved if required.
Quartz Rolled & Polished Plates
Multi-Lab stocks a large range of quartz glass plates in various dimensions
and material grades. Also the company holds stocks of high-quality ingots and
block material which allows a higher versatility in terms of shape, size and
Quartz Cones, Sockets and Cup & Ball Joints
All Multi-Lab standard quartz cone and socket tapered joints maintain high quality
with such properties as surface finish, uniform wall thickness, and accuracy of
taper. They are also tooled or machined on Momentive or Heraeus material
ensuring a first class product every time. In certain cases Multi-Lab used
thicker walled material than the industry standard for greater strength to
assure reliability. The company currently supplies cones, sockets and ball
joints from 5/20 up to 230/60 and can supply larger diameters’ on request.
Ball & Socket
All the joints from Multi-Lab have the following advantages
- Bevelled edges for greater chip resistance.
- Exclusive extra heavy rim on all outer joints for greater impact resistance.
- Standard taper joints comply with the ASTM specifications E676.
- All standard taper joints are ground to a 10:1 taper.
- Large stock levels held.
- Non-standard taper joints and longer lengths are available for quotation
- Quartz Sockets and Cones conform to ISO R383: 1965 and BS 572/60.
- Spherical Ground Ball & Cup Joints (BS2761).
Quartz Sintered Discs
Multi-Lab holds stocks of sintered quartz filter discs in various porosities and
dimensions, six different porosity types are offered from extra coarse to extra
fine allowing precise adjustment to the particles to be retained during
filtration.Standard disc sizes ranging from 5 mm to 120 mm outer diameter and
thicknesses between 2.5 mm and 8 mm.
Fused Quartz Discs
Quartz wool is a stock item packed in bags 2 to 12 or 5 to 30 µm as10, 500 and 1000
Fused Quartz Wool
Multi-Lab is one of the leading High Purity Natural and Synthetic Quartz
Glass distributors in Europe. Multi-Lab has always been a defining force in the
sale and fabrication of quartz glass within the Semiconductor, Fibre Optic and
They are also able to manufacture a range of components to customer
specification in various other technical ceramics such as alumina, zirconia,
silicon carbide, steatite, boron nitride, cordierite, silicon nitride and
