Z-Glass Brand Filter units contain an integrally sealed fretted glass support bed which rightly ground to match a funnel for holding a 25 mm./37mm. / 47 mm. dia. Filter membrane. The unit is deliberate to make the most of flow and diminish foaming and protein penetration. The filter funnel support bed and receiver flask are fitted with interchangeable ground joint and one Aluminum Clamp is provided to hold the filter funnel and support bed appropriately. One  cover made of polypropylene is also provided to protect dust. The total unit is autoclave. Another model is available with silicone rubber stopper  fitting in place of ground joint fitting. Three different sizes are available.

Stopcocks (Vacuum proof)
All Z-Glass Brand Stopcocks (vacuum tested leak proof) are made ruggedly manufactured with hollow piston and a conical flange, which guaranteed maximum power at the seal of arms, and are individually smoothly lapped to the comparable barrel. Therefore these are not interchangeable but guarantee in vacuum work. A various range of models is available for individual use of work in laboratory. So the exquisiteness of Z-Glass Brand stopcocks are the smallest possible interspaces between the barrel and piston. Available in the following models from 1mm to15 mm. bore.

• Straight bore
• 2-way oblique bore
• 3-way ‘T’ bore
• 3-way oblique bore
• 3-way ‘V’ bore
• 3-way twin (tail) bore

High Vacuum Stopcocks
All Z-Glass Brand High Vacuum Stopcocks are manufactured to take some unique techniques are taken in lapping to make possible it to withstand against use in a vacuum up to 10^-6 mm. of Hg. Each piece of Z-Glass Brand High Vacuum Stopcock is tested in High Vacuum Unit before it comes to customer’s end. Available in the following models from 1mm. to 10mm. bore.

• Straight bore
• 2-way oblique bore
• 3-way ‘T’ bore
• 3-way oblique bore
• 2-way oblique with bulb
• 2-way oblique with cup & bulb
• 3-way oblique with cup and bulb
• 3-way ‘v’
• L-type 2 limbs
• L-type 3 limbs

Stopcock with PTFE Plug
All Z-Glass Brand Stopcocks with PTFE piston have completed in optically ground glass barrel and lapped properly to match and leak proof and so chilly problem is eliminated. Available in four following models from 1mm to 6 mm bore.
